SD cards - MDA, XDA, 1010 General

hi all ive read a few quotes from you all about sd cards and the problems you have had, im after buying two sd cards a 128mb just to store music on and a 512mb for media files / dvds/ films on. the question is what card or cards would you recommend as there are so many out there and some do not work or you have had problems working, your feed back is most welcome

I have a 256Mb Lexar with 32x write.....
Regardless of what card you buy, I've heard complaints about data being erased from the card on the WM2003 OS.... Its really annoying.... It has happened to me too.... So I just keep the card locked....
Apart from that, no complaints with the Lexar card I have.... works like a charm.... All the cards that are out there are good.... Lexar and Sandisk seem to be the more popular ones....

Hi, I've just got a Kingston 512MB SD card, are they any good? I do not have my XDA II as yet but am hoping to get it some time this week (waiting on stock )

I am getting very slow speeds on my SD card, even in a SD card reader in Windows XP a few friends have also reported the same problems of speed changes and slowing down... any ideas?

I also want to buy a Kinston 256 for my XDA running on WM2003. ANy comments on the speed or reliability of Kingston? I also have eyes on Viking and Smart coz they are the cheaper ones. Any comments on those brands?

Unfortunatly I have not been able to get my hands on any others, but the Kingstone ones seems to be working with no trouble what so ever so looks goot but not sure how fast they are ment to run or any thing like that so can't offer much information unfortunatly...
Can any one shed some light on the subject for us????

there are tons of sd card benchmarks and comparisons just search google
http://www.google.dk/search?q=sd+flash+benchmark&ie=UTF-8&oe=UTF-8&hl=da&btnG=Google-søgning
from that search i found this
http://www.core-sound.com/CF-and-SD-mass-storage-comparison.html

Thanks for the links
I've been through google a bit but there is so much out there I was wondering if any one found any decent ones that are well laid out with graphs and all... comparing many brands of SD...

well i would search on these 2 sites i recall a test of what you are looking for just with CF cards i'm not sure if a company's CF card speed give an impression of their SD card speed or if they also have SD card banchmarks but anyway (sandisk were always last when it comes to speed )

2gb sd cards?

I am very impressed with this site i have just updated my xda to wm2003, was nervous at first but impressed how easy it was.
The next thing i want to do is to get my 2gb sd card to work with it, I have been through the forum and read other threads about people managing to make them work and also downloaded pocket mechanic to try and forma the sd card in my device however it is still only registering as a 1gb sd card, does anyone have any ideas how i can make it work with the whole 2gb since i went and bought the card especially.
many thanks

do sdcard readers see it as 2GB and or cams or other SD using devices?
my sdcard reader reads it at 2gb (or 1.91) not tried my camera but if pc is saying 2gb would think it would be same in my camera

8GB Micro SD

Ok, so from my research, the 8GB Micro SD is not yet widely available or even on the shelves (correct me if I wrong). But, according to the various sites I've looked at these size cards are well on there way to being released.
I know the new standard of SDHC SD card are available in 8GB and possibly above, but I have now got a Hermes, so wanted to try going higher in Micro SD. Presently I use both a 2GB and a 4GB Micro SD, depending on what I'm needing to store.
Size wise 4GB it great as options for storage are vast.
But I wanted to see it there was any further news as to the new 8GB or higher that I'd read somewhere?
Having looked on line I could only find the following:
6GB Micro SD
==========
Pre-ordering only?
1: http://www.mymemory.co.uk/memory/SanDisk/6GB/Micro/SDHC/Card
= SanDisk 6GB Micro SDHC Card £69.99
8GB Micro SD
==========
Pre-ordering only?
2: http://www.mymemory.co.uk/memory/SanDisk/8GB/Micro/SDHC/Cardhttp://www.mymemory.co.uk/memory/SanDisk/6GB/Micro/SDHC/Card
= SanDisk 8GB Micro SDHC Card £99.99
Since upgrading the Hermes ROM on my phone to WM6 which was purely to allow it to use the 4GB Micro SD I had bought (I swear by SanDisk as have NEVER had a problem with them in over 5 years of assorted SD cards)
Am going to keep looking over the next few weeks and would be interested in any feedback if any others have found any news about higher capacity versions.
I have no idea if WM6 will be able to read higher than 4GB but my guess would be a resounding YES! on the grounds of what I have a feeling is WM6 full? SDHC support. whereas WM5 on the Orange version of the Hermes 'SPV M3100' had only partial support and can only recognize 2GB sized Cards.

PS: if this post is in the wrong place or out of date can a mod sort it out and remove or move it. Many thanks. Just wanted to share my interest and findings on these Micro beasties thats all.
You accidentally posted the 6GB page, if you change the "6" to "8" in the URL you'll get what you meant for the second post.
Wow thanks for those links can't wait to get my hands on 8GB of freakin memory! I'm very impressed with MicroSDHC and am so glad the Hermes can take the always (albeit gradual) increasing card capacities, without new hardware needed.
Take that, iPhone! (don't worry, i love you too)
I found it very difficult to get a 4gig microSD card in the US. I keep seeing these cards in the UK but they don't ship here. Does anyone have links to any companies for even a pre-order.

The six (6) GB link was intentional bud. I have researched "above and beyond" the 4GB size. Happened to find the 6GB link on same site so added it as I didn't know if like myself others were also unaware of this specification.
Cheers anyway.
You missed his point, your 8gig link is incorrect, it links to the 6gig ad.
Wow, 8G! Wish I had known that before splashing out on an 8G Zen MP3 player.
Thanks for the spot!
Are you sure the hermes does support the micro sdhd?
I wrote yesterday to htc to ask what is the max size of microsd that hermer support, and the follow is the answer:
[....]
Good morning
The max size card your device supports is 2GB. It will not support HC (High Capacity) memory cards. Please see our recommended product below:
http://www.expansys.com/htc/p_htc_item.aspx?i=143529

Teorically an microsd reader could be support the HD format through a firmware update...
Ps: What is the difference betwen micro SDHD and micro SDHC?

MattiaRs-- There many threads in this forum about people using sdhc cards in their hermes with the newer builds of ROM. You gotta search and read.

When a representative from Orange looked into this on my behalf, he also was told me that HTC was only recommending that the Hermes be used with 2GB Micro SD cards, as that was the limit they (HTC) would guarantee.
When I first tested cards out prior to a firmware update to WM6, the above was indeed true.
However, my Hermes now runs WM6 and uses a 4GB SDHC Micro SD Card on a daily basis without ever having a problem.
I have no idea if this will be true of higher spec cards such as the 6GB or the 8GB or even anything higher, but I feel confident that it will. But that is just my opinion as until tried and tested its down to guesswork whether or not other card sizes will be recognized.
PS: you asked what is the difference between micro SDHD and micro SDHC?
The answer is that I have NEVER heard of Micro SDHD. To me that is a High Definition tag and not one that refers to any card type.
I've only ever known SDHC.
Even Google comes back with: "Did you mean SDHC" Maybe others know of this type of card?

You could walk into a verizon store anytime and pick up a card, if you wanted. Other people have been able to order 4gb cards-- you could, also. READ!!!
Transcend 4GB SD with Exec loses data randomly --please help.
Hello there,
I read you people are using 4GB SD without any problems, you might solve my problem.
I am using one on my Exec with WM6,(ROM 2.02.02,Radio 1.15, Protocol 42.51.P8, no ext rom) and facing a weird problem.The card loses the data for no apparent reason.The folder viz. My document has just been emptied and I lost my all ebooks--150 MB.
The file explorer shows the card contains 776 Mb data while the 'Resco explorer' shows 1007 Mb,in setting-memory-storage card it shows 1007 Mb,but it actually has only 776 Mb data, so I have lost 150 Mb data permanently and 300 Mb storage space on card!
This is the THIRD time it has happened and on previous occasions I had the card replaced.I am fed up with this problem,is it the card itself or the Exec or the WM6 or the ROM which is causing this problem?
Is there any way to retrieve the data and the memory lost from the card, for I think it is there and it just hidden somewhere...I hope.
I am not a techie,(medical doctor--using Exec more as a PDA than a communicator)hence the lengthy description ,thanks in advance,sorry for the intrusion.
bye.
sorry for the hastles your having
I wish I could help you further but apart from what I have read relating to the Hermes I can't.
I would hazard a guess and say that it sounds more like the Operating System / ROM which perhaps is not handling the card properly.
Best if you put up a new post on the main board and ask for help.
I hope you get it sorted as I know from my own problems similar to your missing card data how really annoying this problem is. I do know that I have had two SD card made by transcend. I used them for 6 months without a hitch. I put movies and files on them both for University and work use and used them in my previous phone which was an English version of the Prophet (Orange SPV M600)
Point is that in my own experience, Transcend are indeed a reliable brand or storage card. So it doesn't sound like a card problem in my opinion. Perhaps you may new to look at updating the ROM? I have no knowledge of your phone model "Exec" so can't help. But as I said best if you ask for help on the board. Maybe on various boards if you've had no luck already. Someone may have previously owned an Exec and might be able to shed some light on this problem.
Kalya-- You need to post your problem on the Universal forums, not the Hermes. There, hopefully, you will get the help you need. Different models react differently to various things. May you find your solutions...

From what I've been told, Sandisk made a deal with Verizon so they are the only approved suppliers in the US for one year. You can buy the 4GB miro SDHC card from them or any Verizon distributor (even Circuit City). However, they are more expensive than Amazon...

[Q] HD2 microSD card

Taking delivery of my phone soon.
What's the latest on microSD cards?
Are 32GB worth it? Do they work?
Any particular minimum Class I should get, even if I have to get 16GB?
Thanks

am using class 6 works fine.
I use an 8Gb, class 4 without any issues. Resco is installed on the card.
Although if your going to flash a ROM from a micro SD card use one < 8Gb.
Thanks,
Al
From my experience, it's not the class or size that matters. It's the make. (Obviously a smaller card with a higher class will have faster r/w speeds, but that's not usually a noticeable issue.)
I never buy any SD cards now that are not SanDisk, and I can't remember the last time I had one that didn't work.
Some brands seem to get a lot of complaints.
The class wouldn't really matter if you're just using it to store data/apps.
I use a Nokia N900 and run Android off the SD card. A higher class gives a better speed when running an O/S off of one. But using one to store data/apps wouldn't give a noticable advantage of one class than another.
Obviously the size does matter but depends on what you'll use it for.
Plus for flashing use < 8Gb.
Thanks,
Al
PS. I agree with the brands. I don't buy cheap non-branded ones. Although I've never had an issue with any of the 'cheap' ones.
The size of the card depends on your needs. If you cram a lot of stuff in there or apps, then aim for 16gb or 32gb.
You can find 32gb on amazon from $70 up (sandisk, kingston, dane elec -- those are deem legit 32gb cards) and most of them should give real class 4 performance (even when they're listed as class 2 like sandisk).
For me I like San Disk,but I want to test Toshiba 16GB Class4.The seller told me that Toshiba quality is good also and I decided to buy it.
Never had any problem with file transfer and running android on SD card.
I've used it 4 months now.So far so good.
I use a kingston 8gb class 4.. Never had any issues with performance
Thanks for all the replies guys.
I'll probably run Android off the card initially with the standard WM 6.5 tweaked. Maybe put some SatNav on there too.
As for Apps depends what I come across. For WM I have an old large build of offline Wikipedia and some dictionaries etc.

I had my 8GB SanDisk in my G1 for 2 years, then my HD2 for about 8 months, then randomly one day it stopped working.
If I plugged it in, all of my content appeared on the phone such as pictures. Then after about 30 seconds it would freeze, and then the phone would say no SD card is inserted. I managed to copy all of my pictures across on the PC luckily before it froze.
Granted it was old - but they do fail after a while.

[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.

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.

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...

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.

[Q] what are the SD card requirements for 2014 tab pro 10.1

Hi all,
I have the 10.1 2014 tab pro and I want to get a new SD card. I know from my brief reading through these forums that not all SD cards will work and I dont know enough to really understand what is what (like what does "SDHC Tf Class 10" mean?). If anyone knows what it is that I need to look for before buying one so that it will work fine with my tablet please post here.
ps I am using these primarily to store books and documents, not videos or games or anything that really takes a massive workload or speed requirement.
pps Im not sure if this matters, but I am running stock unrooted
TIA
Most any newly purchased MicroSD card should do. What did you read won't work? Below Class 10 cards might not work for some high speed functions (like video), but I believe all should work for casual use like you describe.
SDHC versus SDXC mainly refers to the capacity of the card, which you are probably going to be looking at separately (in GB) anyway, so it really doesn't matter. Basically, the original SD standard (also called SDSC) was limited to 2 (4?) GB. SDHC increased the capacity up to 32 GB, and anything higher than that is SDXC by definition. There are some other minor differences, but probably nothing you really need to worry much about.
Class (8, 10, etc.) refers to the read/write speed; but you may also see a UHS speed classification (U1, U3) also. Even though you are not talking about high speed demand tasks, I'd still tend toward Class 10 or U1 cards. Just in case you change your mind about what you want to save to the card; and many cards meet Class 10 or U1, anyway. For the few cards that you can find with lower speed class, you might save $10, so its probably not even worth it to consider lower speed class cards.
The following Wiki articles goes into a lot more detail about the specs: http://en.wikipedia.org/wiki/Secure_Digital
Out of all this, I'd be more worried about brand, or getting a counterfeit product. Some cheap or off-brand cards seem to fail more frequently than the big names. Folks all have their favorites, and may argue that you are just paying more for the brand. But I've bought several Sandisk cards, and never had any issues (and heard similar from other users on XDA).
I'd also stick to a reputable seller (Newegg, Amazon, etc.) as places like eBay are awash with counterfeit SD cards. Its so easy to relabel a card as a higher capacity (i. e. take a 32 GB card and label it as 128 GB, etc.) and even spoof the device to read it as the "fake" capacity, than charge much more $$$.
I am using one of these on my TabPRO:
http://www.amazon.co.uk/Samsung-MicroSDHC-Memory-without-adapter/dp/B00AYC6V2U
Works fine on all my Android devices.
And to really leverage it outside of Google Apps and pre-installed items you need to root and enable write to the SD card, unfortunately. (Unless I'm missing something.)
Thanks, I really appreciate that info on what all those terms mean. However, right now I am using a 32gb Sandisk ultra, and my data keeps getting corrupted, apps cant find it, showing up empty on every file explorer I try.... Therefore I thought since Sandisk is legit (I bought it at costco so its real Sandisk) I figured there must be some issue with the type of card.

I had similar issues with a genuine SanDisk card in my S3 (couldn't access it in recovery either), just showed a bunch random characters instead of file names etc), swapped it to a different brand (I got a genuine Sammy one because it was a bargain at the time) and that solved the problem....
