SanDisk 32GB Class 4 High-Speed MicroSDHC - HTC EVO 3D

Hey there fellow XDA members.
I caught wind of the deal that is going on at "1saleaday" early this morning and wanted to hop on it right away, but i decided to ask here first for some more knowledgeable advice. I currently have the stock 8GB which if I'm not mistaken is a class 4. Would it be wise to switch to the 32GB class 4? I did my research on how Class 2 and 4 cards have better random access speed and random read/write than class 6 or 10 cards in general. Source
I'm mainly using it for flashing rom's and themes, photos, music, etc. So what class would you guys suggest? Also if anyone has jumped on the deal, is it legit? What are your experiences as far as shipping time?
Thanks for any info on this matter.
Finally, as far as making the switch from one memory card to another, is it just transferring the data "drag & drop" style? or is it more complex?

I don't think you'll see a performance change going from 1 class 4 to another regardless of size, but I could be wrong.
as far as transferring data - yes. Drag and drop. I've copied whole sd card to the pc, put new card in, then copied data from pc to new card. But, you may have to do it in small parts at a time - I kept getting freezes and such but my card at the time was bad too (why I was switching) and my computer also wasnt at 100%

Speed wise i don't mind, as long as it works exactly like my current one but with more storage space I'm a happy camper.

Your a little late to the party. I started this thread at 2am this morning in the accessories sub forum.

16 GB micro sd class 6 card for our HD

i'm interested in the two following cards that i found on e-bay:
http://cgi.ebay.com/TOPRAM-16GB-16G...C_Drives_Storage_Internal?hash=item4cec018066
http://cgi.ebay.com/NEW-EDGE-Tech-1...gital_Camera_Memory_Cards?hash=item5d26f2c39e
did anyone maybe bought the and tried them?
I never heard about those manufacturers before so I'm interested in the quality.
Micro SDHC Card.
Hi !
I have been testing a lot of different cards, and my recommendation is this
Transcend Micro SDHC 16 GB Class 6
And it has lifetime Warranty!
With kindly regards MacRoy
MacRoy, thanks for your post
I know tha Transcend and San disk are the leaders in this field but i'm interested in the above mentioned cards because they are the cheapest i could find on e-bay.
I would like to know if anyone has actually used them so they can tell me what is their quality?

Just purchased this one myself, waiting for it to be delivered. An 8 GB Class 6 Transcend card came with the purchase of my HD and it's been the best card I've owned so it was an easy choice for me. I wouldn't go cheap on something like this personally, you get what you pay for.
I bought the 16gb class 6 earlier today because my 16gb class 2 is starting to give me and my computer MAJOR problems. Up until now, the card has worked like a dream. I can't wait to see how much faster the class 6 will be like
i bought this card a few days ago
http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=250561131115&ssPageName=STRK:MEWNX:IT
waiting it to come...
i'm hoping it's gonna be delivered in a 2 weeks period so i'll give my opinion then on the card speed
the card has arrived....
by putting it in my PC the higgest speed I got was 5,2 Mb per second
I would like to make some more test so if anyone can give me some tool for testing the actual speed of the card I will report back with the results...

thanks for the link
I have attached the screenshots of the results...
I have taken 100MB and 1MB in the settings. If that was not ok, please tell me what to put and I'll make the test again...
by this I screenshot I would say that the card is 6MB or am I wrong?
hello,
I bought the "Transcend Micro SDHC 16 GB Class 6" and since I can't flash any ROM, I formatted the card several times (FAT32) but to no avail,
you see the same thing?
Also this card is not compatible if you want to switch on Android.

my card is not transcend but I didn't formatted it when i got it... i just made a restore to defaults and once again installed all of my programs on it.. did you try that?
maybe you should format it with NTFS instead of FAT32?
but i don't understand why you said that you can't flash any ROM? did you try doing that already?
Looks good. Did you try copying 16GB worth of data onto it ? Some of these cards could be fakes and have lower capacity than stated.

by now i have 13,1 GB of data on the card... still haven't filled it to the end
in the SD properties on the phone it says 15185.50 MB of storage availabe... i suppose that that is 16 GB...
I know youre all speed freaks - and youre talking about the class 6 cards...
But i just ordered this one (16GB, Class2, ~22$) (urgh - china product... - i never trust those *g* - but the price is just half of all i've seen before)
http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=270528336681
as the 8GB delivered with the HD also just was Class 2 i thought thats enough for me...
And it's just a third of the price for the class 6 cards youre talking about.
Actual my question is - what do we need class 6 for?
Don't missunderstand me - I don't want to flame anyone for buying class 6 - but in my case about 7 of 8 GB are static on the card (means i transfered it once to the card and it never changes - Music) and 1 GB is dynamic (new Progs and new Music,...) but even this doesn't change every day all at once but about 20mb every day (max).
So with class 6 we save some time on the first copy progress - agree.
And every day about 10 seconds.
I know the example above is just for me but I think it would fit for most of u *g*
So why all people are so keen on this class 6 ? (i ofter read about in this forum not just in HD section)
btw. the tested speeds of those cards - most are tested in external readers are they? Does our HD even reach them in USB mode? or even worse - in ActiveSync mode? Cause i don't take my card out every day to copy some files...
greetings
Edit: k some people might watch videos on their HD every day which could take a while to sync - but USB and ActiveSync quests are still out...
forgot the video thing - cause i just once watched a video on my HD half -> battery life is not made for in my opinion

it all depends on what do you need it for...
for me class 6 saves me a lot of time because i download approximately 10-20 GB of music a month, and somwhere about 20 GB of movies and tv shows...
so basically i transfer somewhere around 1-4 GB a day from my PC to my card...
true, if you're doing that through the USB or ActiveSync you probably won't see the difference, but i often don't have the time to do that so I use the microSD adapter and transfer it a lot quicker to my sd card than it would be done through the USB or ActiveSync
on the end it all depends on what you're looking for and for what price...
Class 6
From what I see, don't bother with class 6 16G. I bought one. Testing the speed on sd card is great but once it put it on HD, it's no different than my Class 2 8G. Could have just purchase a Class 2 16G.

Hi,
I just got an email from ebay asking me not to finalize this order because of problem with the seller.
It seems that this is a scam.
Be careful.
Bemi
the question is not "what is the fastest class 4/6 card" in my eyes.
I bought the HD with the standart 8GB.....class "dont-know"...
of course I thought following:
higher class,bigger card = more expensive than slow and small...
so I tried to find out which card is included....
I found NO information about it. there is nothing to find on the HTC site.
no seriuos information to find on forums...
and nothing "written" on the card itselfe.
so I thought about buying the best and fastet card (testet with real test equipment).....
BUT
because the card-speed is degraded by the hardware you try to read/write....
and there is not a single information to find about what a HTC HD can handle....
(I asked the HTC support and did not get an answer at all)...
I decided to DONT buy another card at all....
I see no advantage to buy the fastes card it the cellphone is not able to use it.
SO : Is there anyone here, how can say that it is worth to buy a class6 card e.g. ??
if : where do you got the information a HD can handle the speed at all ?
thanks

i bought the A-Data 16gig Micro SD card with two adaptors class 6 card off ebay for $54.99 and works great in my MyTouch 3g very fast and it has a lifetime warranty on also

PNY 32gb class10 SDHC, mounted once, and never again?

so I just bought this card cause I use lots of storage space pretty quickly, My question is wtf is going on here? it just sticks on "checking for errors" and never gets past it, it mounted up once and while I was dumping files on it over USB from my computer (in usb mass storage mode) both it and my internal storage just disappeared, the copy operation failed, so I restarted the phone and I have yet to get the phone to mount it since then.
I'm running eclipse 1.3rc2, is this because of the sd flip-flop, the size of the card or the fact that it's class 10?
the card works perfectly fine in my camera, and in multiple PCs, but as soon as I stick it in my X2, it just doesn't want to work.
I noticed the stock SD card has a "bootable" partition flag, whereas this one doesn't. maybe this is my problem?
also what filesystem should I use, I run linux on my PCs so I can do whatever I want with it.
what if I just delete its partition table, put it in the phone and then let the phone format it? I've reformatted it with my PC and no dice.

When I got the 8gb card and using now it was acting weird ...would copy files when in the phone. I formatted it using the phone and it has worked fine since.
Good luck.
I can't say it will work for u but it cured the problems I had at the time.
just make sure u format the right card since in eclipse its switched around and recognized as internal in menu.
well, It took exchanging it for a class 4, and now it seems perfectly fine.
so note to self (and others)
NO CLASS 10 CARDS IN DROID X2, IT DOESN'T FN WORK!

I don't think that is true...I thought I saw plenty of users say they use them.
Mine is class 6 and works just fine
Did u try formatting from in the phone while stock? Don't know if that would make a difference at all
I didn't read one single thread from someone successfully using a class 10 card without having issues, sometimes it took a few days/weeks, it only took me one mount/dismount cycle.
besides, the class 10 cards, while having a higher sustained transfer rate, their seek times and random access times are overall slower. basically these class 10 cards are ONLY good for digital video cameras and things that don't actually utilize a filesystem.
that or they're getting cheap chinese cards that are just remarked class 6 cards, the X2 can't read and write to a class 10 fast enough resulting in data corruption, period.
Yeah im not arguing
I understand what ur saying now
I can confirm class 6 being completely fine tho
I think the "issues" I had was the file size I was trying to transfer(4gb)
I don't think it's the class rating but the capacity. In my experience 32 gb cards just aren't as reliable as smaller-capacity ones. Perhaps it's a consequence of packing too many memory cells into such a small form factor, I don't know, but I've had three 32 gb micro-SD cards fail on me since the beginning of the year, whereas not a single 16 gb card has failed me yet.
I just dumped 4.8gb of crap on it, over usb and it took it like a champ, it's also significantly faster than the stock 8gb card in terms of mounting, remounting, scanning my media and even opening up fileexpert is faster.
class 6 i'm sure is fine, probably the best balance, but I can even take HD video straight to this card with no frame dropping or glitching. it's currently playing hd video on my hotel room TV right off the SD card w/ no issues (the stock 8gb couldn't do that)
Ha. Mine came wit a 2gb class 2 sdcard ...
Wait...now that I think about it.. I had bought a droid pro initially. It had a screen issue...I took it back and paid extra to get the x2. Then I told em I didn't wanna lose my pics/video I had taken and he switched the cards. So I guess he basically just kept the one I wax supposed to get instead of moving my data to the new one....prick...

16gb NT SD dual boot w/CM7 - Just me or really unstable?

Brand new 16gb NT. Dual booting CM7 from the SD card, which is a brand new PNY 16gb Class 10. NookOS still on the internal. It just seems unstable-y to me.
First of all I have the wifi issue which seems to be common. It drops the signal quite a bit even when I have a seemingly strong commection and also doesn't always want to turn right on after sleep. I'm willing to chalk some of that up to my router, especially the dropping, but I thought I'd mention it for posterity.
I also get lots of reboots. It seems to happen most when I have a few things running. Have the gall to install an app while having Gmail open, then the audacity to open Gtalk on top of that? Boom! Reboot. You get the idea.
It's also just sluggish in general, be it with web browsing, games, music, etc. Netflix makes me feel like I'm running it on a Pentium II. And Yahoo mail arguably doesn't work it's so slow. Lots of system notifications and "force closeds."
I've also had the issue where I couldn't get it to boot CM at all. It would get to the splash screen then freeze and reboot. More than once I had to reformat the card and start over.
Surely this isn't what I should be experiencing. Will it help to root it and install to the internal? I wanted to keep NookOS on there in case I want to sell it and upgrade.
Any thoughts?
I started with the PNY and found the same thing. I switched to an 8 GB Sandisk Class 4 and could not believe the difference. It has to do with the small block write speed and the PNY is SLOW.
There is a lot of material in the forum about what brand and speed of micro sd to use. If you are curious you can search.
I have a 32 GB Sandisk Class 4 on order and intend to transfer to it when it comes and I find out how.
Bill
Its likely because you are using a higher class sd card. Drop down to a class 4 and you'll see an improvement.

So is it the class 10 cards altogether, or just PNY?
I would say class 10 in general is a bad idea. Its a misconception that higher class = better, in general. They are better for camcorders/digital audio recorders, but that's about it. In general you should stick to class 4 cards.
I can't speak on that brand personally. I only use SanDisk cards.
Amazon has the 32 GB Sandisk Class 4 for less than $16. You can get 8 gb for less than $8. Go for the bigger one if it fits your pocketbook.
Bill
Ok, so I have to get a new card. Maybe I can unload this one on Craigslist.
What about just rooting it and installing to the internal? The only thing is now I guess the NookOS is bricked as I cant get back into it. Can I unbrick with a class 10? The thread said to use a class 4.
If you want to run internal cm7, simply create a clockworkmod bootable sdcard (same process you did for cm7 on sdcard, but with the cwm image). Then download the cm7 zip file to the sdcard or your internal memory, boot into clockworkmod via the sdcard and install from zip. Download and install gapps in clockworkmod as well if you want the play store/google apps.
A quick question off topic...I went to get a copy of the internal CM7 and the link in the development forum isn't working...any idea where I can find a working link?
Thanks,
Nikkie

[Q] How to keep your micro SD card Healthy. Extending the life...

Over the years I've owned about every brand of cards from eBay cheapo's to the best the industry has to offer like Samsung. I shoot HD wedding videos, take millions of pictures and edit so micro SD cards have been a necessity.
It just dawned on me today when I was looking at the mountain of SD cards I have in my office and realizing the life span on all the cards I've used over the years. Therefore, I'd like to share my experience along with asking those who are knowledgeable in the area of memory cards to help answer some of my questions.
I shoot HD videos and take lots of pictures on my Note 3 so having a reliable card is very important to me. Currently I'm locked and loaded with a 64GB | Class 10 | SanDisk microSDXC UHS-I card in my Note 3. (I also have a Samsung 64GB PRO Micro SDXC | Class 10 Memory Card (MB-MG64DA/AM), which I use in my Canon Video Camera and it is by far the best card out there. Period.)
The 6 most reliable cards that I've owned throughout the years: (Best to Worst)
Samsung
A-Data (Samsung chip, go figure. However, they are highly likely Samsungs '2nd hand' chips as they are not as fast as the actual Samsung brand labeled chips.)
PNY
SanDisk
Kingston / Sony (tie)
Transcend
It's not worth listing the other non-brand ebay junk so I've left those out.
Lately, I've been very disappointed with SanDisk's quality. Especially with their Class 10 cards, where I have found them to have a very weak 'integrity' in their chips. A good card should give you about a million write cycles. (Write cycles is a whole another can of worms...)
I have had more failed SanDisk's (lemons) cards than any other brands combined. This is why I will never buy SanDisk again and am switching to what has never failed me, Samsung. I can't afford the chaos and hate having to recover priceless wedding pictures from a card who decides to kick the bucket when you need it the most.
Recently my 64GB | Class 10 | SanDisk in my Note 3 decided to go belly up and I had to use a data recovering software to salvage all my 4,000 pictures and hundreds of HD video's. WTH right? This card is a couple months old. My previous SanDisk in my old Note 2 did the same thing after a couple of months.
ME, MYSELF AND MICRO SD CARDS...
With a new card I reformat it to Fat32 with Disk Utility (Mac) and then pop it in my device.
Since I take a lot of pictures / videos, I connect my phone to my computer (Android File Transfer, works flawlessly on Mac), copy over everything to my hard drive, back it up again if it's important and then properly eject the phone/card. I've always read and heard from camera guru's that it's best to reformat your card from the device instead of deleting the pictures in the folder from your computer while it's still connected. Therefore, after copying over the pictures/videos I would immediately eject and delete directly from the phone. The 'theory' surrounding this is that if you leave your card connected to your computer, it will access (checking byte order/changes) the directory more times than you would want it to thereby decreasing the life expectancy of the card.
Now of course it's not convenient or practical by no means to do this every day with your Note 3...most people just plug in and play with no problems whatsoever throughout the life of the card.
QUESTIONS FOR THE GEEKS
Explain the difference in the structural integrity of the internal SD card vs external SD card.
How much more life expectancy / write cycles does the internal card have vs an external card?
For a heavy user like me I have always put everything on the external card to avoid using the internal memory as much as possible avoiding unnecessary stress.
How often should the external card be reformatted for a heavy user like me where I'm constantly copying over, deleting, etc...
To be continued...
I don’t know about card in deep technically but all I learned so far, generally cards these days have very long life span, at least average 10 years, unless physically damaged or any uncommon technical issues.
I too concerned about this too earlier but now technology is so fast upgrading you shouldn’t worry about its life span. Technically what I know its life span also depends on it read and writings like you said and even if your car had heavy use then there is no point to formatting it frequently. Card is not like windows which creates junk files by time. Deleting and formatting does the same thing and both will free up same space if you delete all, where formatting read or write more data than deleting. So formatting frequently could reduce its life but that could be unnoticeable. The same way defragmenting, shredding also reduces its life. But shredding is good if I lost it any other couldn’t restores any private files.
So I think there have no logic to format it frequently to keep it healthy, unless its corrupted.
By technology is so fast upgrading what I mean is like, few years back I brought a new phone and brought the best card at that time, it was Samsung 32GB class 6. It was best on the market during that time. But then class 10, pro, plus released. Then when I got note 3 I had already a 32 GB card but I brought a class 10 pro one due to the HD recording. So after 5 years from now even if this card is working I will still have to buy a new one, as there will be far better technically upgraded one. I hope I make sense.
And I too use Internal memory very less, as loads on internal memory make the phone slower.
Thanks for the reply. I agree that with a decent name brand of a card, the life expectancy shouldn't be too much of a worry. My experience with SanDisk has been pretty poor in that I don't think they make cards with good quality material. As mentioned, the structural integrity is very weak. Their older cards were better. The newer ones in my opinion and from my experience have to be treated with a mentality of 5 years ago, because they do wear noticeably.

Technically what I know its life span also depends on it read and writings like you said and even if your car had heavy use then there is no point to formatting it frequently. Card is not like windows which creates junk files by time. Deleting and formatting does the same thing and both will free up same space if you delete all, where formatting read or write more data than deleting. So formatting frequently could reduce its life but that could be unnoticeable. The same way defragmenting, shredding also reduces its life. But shredding is good if I lost it any other couldn’t restores any private files.
So I think there have no logic to format it frequently to keep it healthy, unless its corrupted.
By technology is so fast upgrading what I mean is like, few years back I brought a new phone and brought the best card at that time, it was Samsung 32GB class 6. It was best on the market during that time. But then class 10, pro, plus released. Then when I got note 3 I had already a 32 GB card but I brought a class 10 pro one due to the HD recording. So after 5 years from now even if this card is working I will still have to buy a new one, as there will be far better technically upgraded one. I hope I make sense.
And I too use Internal memory very less, as loads on internal memory make the phone slower.

I know that feel of losing data, I have had 3 64 GB SanDisk cards die since January - right now I am using a 8GB. sad n true
Wow, sorry to hear. That sucks. Then again, you've verified my point even further about how crappy SanDisk cards have become.
Let your next card be a Samsung. I'm weeding out my stock of cards, heck I've given some away already.
Here's the best: Samsung 64GB PRO Micro SDXC | Class 10 Memory Card (MB-MG64DA/AM)
I use it in my Canon and it's extremely fast.

That Samsung card sounds impressive, just not ready to spend any more monies on getting one right now.
off subject are you still in Honolulu..

Thanks for the reply. I agree that with a decent name brand of a card, the life expectancy shouldn't be too much of a worry. My experience with SanDisk has been pretty poor in that I don't think they make cards with good quality material. As mentioned, the structural integrity is very weak. Their older cards were better. The newer ones in my opinion and from my experience have to be treated with a mentality of 5 years ago, because they do wear noticeably.

I never used any SanDisk card on phone, only Samsung cards so I’ve no personal experience and I’ve seen many user complains about its compatibility and issues on Samsung device. However I’ve been using a SanDisk high-speed MMC card on my Nikon SLR over last 5 years and still its performing great.
I believe Samsung cards works great in Samsung devices. So far only one card got damaged many years back and that was a stock Nokia card.
I currently have a 64gb sandisk class 10 in my phone I always used sandisk and never had a issue. I can't say the same for kingston. I found out it doesn't mess up when you unmount it when taking it out. I never did that before and they got messed up even if it did get messed up warranty is always there.
currently using the sandisk extreme plus 64gb card with no issues whatsoever. will update this thread once it crap out on me (it probably will in about 6 months) and how the warranty process goes.
I had a 32Gb Sandisk Extreme die in my Galaxy Note 3 while recording 4k video on to it.
Without a compatibility list and guarantee from Samsung, I am reluctant to buy another high end microsd card.
I am sick of these SD Cards. In my Galaxy S3, the thing would ocassionally take a dump and have to be reformatted.
Now I just restarted the Note 3, and boom, card took a dump.
I think I'm going to just live without.
Sandisk has always been reliable for me, apparently there are only 4-5 chip manufacture, and majority of a-data's card are rebadged from sandisk, same goes with transcends, whiles kingston are with toshiba, and PNY is a mix of sandisk and toshiba.
For data recovery and/or SD card repair, had anyone given Spin Rite a try?
I've been using a UHS-I 16GB Team card in my phone, been pretty reliable so far and gets pretty quick read/write speeds. Also been using a 32GB UHS-I Samsung card in my Sony NEX-5T camera, also been having no issues.
Just had my first Warranty experience with SanDisk. My 64 Gig SanDisk Ultra had crapped out by not allowing any write cycle this would not allow for deleting files or format or any changes to card. After a brief chat session on the SanDisk website I had my RMA and got emailed a label to print. My old card was off to SanDisk. 10 days later the new card arrived. This was a good warranty experience. Hope the new card will have more writes.

I'm glad I'm not alone on this. I have my first 64GB microSD on Jan last year. I chose Sandisk because I believe many of tech experts favor them over every other brand. At the time I wasn't at all concerned about its lifespan because I am using it for such a simple task like music storage. By the end of Dec last year, the card refuses to write and format. Folks at Sandisk forum suggested to use SDFormatter, however if you get "write protected" error, your card is not repairable, they say.
I was lucky to get a new one so close to the end of my one-year warranty. But seeing Sandisk cards are getting less reliable these days, I might give Samsung a try if my Sandisk fails again.
Quick question, though: where else does Samsung evo and pro differs beside speed? Does pro have longer lifespan?
Interesting. I've been using Sandisk for well over 10 years in everything from my DSLRs to my phones, never had a single card die on me.
I have owned 3 64GB Samsung MicroSD's over 2014 and they all died within two months.

I agree with you, sandisk is probably the most reliable brand available.
Been using sandisk when the first had them as transflash.

Over the years I've owned about every brand of cards from eBay cheapo's to the best the industry has to offer like Samsung. I shoot HD wedding videos, take millions of pictures and edit so micro SD cards have been a necessity.
It just dawned on me today when I was looking at the mountain of SD cards I have in my office and realizing the life span on all the cards I've used over the years. Therefore, I'd like to share my experience along with asking those who are knowledgeable in the area of memory cards to help answer some of my questions.
I shoot HD videos and take lots of pictures on my Note 3 so having a reliable card is very important to me. Currently I'm locked and loaded with a 64GB | Class 10 | SanDisk microSDXC UHS-I card in my Note 3. (I also have a Samsung 64GB PRO Micro SDXC | Class 10 Memory Card (MB-MG64DA/AM), which I use in my Canon Video Camera and it is by far the best card out there. Period.)
The 6 most reliable cards that I've owned throughout the years: (Best to Worst)
Samsung
A-Data (Samsung chip, go figure. However, they are highly likely Samsungs '2nd hand' chips as they are not as fast as the actual Samsung brand labeled chips.)
PNY
SanDisk
Kingston / Sony (tie)
Transcend
It's not worth listing the other non-brand ebay junk so I've left those out.
Lately, I've been very disappointed with SanDisk's quality. Especially with their Class 10 cards, where I have found them to have a very weak 'integrity' in their chips. A good card should give you about a million write cycles. (Write cycles is a whole another can of worms...)
I have had more failed SanDisk's (lemons) cards than any other brands combined. This is why I will never buy SanDisk again and am switching to what has never failed me, Samsung. I can't afford the chaos and hate having to recover priceless wedding pictures from a card who decides to kick the bucket when you need it the most.
Recently my 64GB | Class 10 | SanDisk in my Note 3 decided to go belly up and I had to use a data recovering software to salvage all my 4,000 pictures and hundreds of HD video's. WTH right? This card is a couple months old. My previous SanDisk in my old Note 2 did the same thing after a couple of months.
ME, MYSELF AND MICRO SD CARDS...
With a new card I reformat it to Fat32 with Disk Utility (Mac) and then pop it in my device.
Since I take a lot of pictures / videos, I connect my phone to my computer (Android File Transfer, works flawlessly on Mac), copy over everything to my hard drive, back it up again if it's important and then properly eject the phone/card. I've always read and heard from camera guru's that it's best to reformat your card from the device instead of deleting the pictures in the folder from your computer while it's still connected. Therefore, after copying over the pictures/videos I would immediately eject and delete directly from the phone. The 'theory' surrounding this is that if you leave your card connected to your computer, it will access (checking byte order/changes) the directory more times than you would want it to thereby decreasing the life expectancy of the card.
Now of course it's not convenient or practical by no means to do this every day with your Note 3...most people just plug in and play with no problems whatsoever throughout the life of the card.
QUESTIONS FOR THE GEEKS
Explain the difference in the structural integrity of the internal SD card vs external SD card.
How much more life expectancy / write cycles does the internal card have vs an external card?
For a heavy user like me I have always put everything on the external card to avoid using the internal memory as much as possible avoiding unnecessary stress.
How often should the external card be reformatted for a heavy user like me where I'm constantly copying over, deleting, etc...
To be continued...

Lifespan? Didn't know they were supposed to "die", or even wear out, and stop working eventually. Been using this same SD card for the past 2 years, and works like the first day I got it.

Life expectancy of SD cards

I just got a new phone. Sliding in the old SD card made the set-up fast & easy. It brought to mind the time my SD card died. It happened 4 or 5 years ago & I've used the replacement card ever since. The first card was only a couple of years old. I'm sure the lifetime is variable, but am thinking maybe it's time to get a new card. Is it?
My 1st card died fast. It worked fine & then it was gone. Are there any symptoms that show a card is starting to fail, or is it always just lights out?
I just found out about SD card speeds. The one I have now is a 4. What is the best speed for a card in a phone? It probably varies with how a person uses it. Do gamers or people who watch a lot of videos need a faster card? What about the user who does those things occasionally, but not that often?
Seems best to find out before it's too late...
A class 10 is the best. Class 2 is the minimum and most Android devices won't read anything that is class 2. The lower the number the more chances it will corrupt.
