16gb Class 2, any difference? - XPERIA X10 Q&A, Help & Troubleshooting

I found this on amazon, pretty much the cheapest and highest i can find on the class category, right now i have a 8GB Class 6 but im running out of space because of the HD videos im recording, will i noticed any significant difference in performance on this phone? and its Kingston and trust them
http://www.amazon.com/Professional-...2?ie=UTF8&s=electronics&qid=1292972644&sr=1-2

anyone got feedback??

I had a 8GB class 2 and the phone needed alone around 3 seconds till the screen went balck and the cam started after pressing the camera key and 1 or 2 seconds till the cam was on.
Now I have a 16GB class 4 and the cam starts immediately (around 0,5 sec after pressing the camera key) and needs around 1-2 seconds till the cam is started.
I think Mediascape etc is also faster with the class 4 than with the class 2.
I don't want to have a class 2 card in my phone anymore, the whole phone feels faster with an class 4 card.
So I'd say you'll feel a difference. If you have the money, go for a 16GB class 4.

it comes with a 16gb class 2
get a class 4 or higher.
preferably a class 6

I read that the phone can't use the performance plus of a class 6 card compared to a class 4 one, so a class 4 should be the best choice.

I'm using 16G class 10 that i bought from Amazon
it work with my X10 and never had any problem until today.
effect: Camera and music are faster then the 8gb c4.

forgot to post the name of my 16gb c10 micro sd brand: kingmax

Good, bought the same card yesterday, hopefully it will he shipped fast. Changed from a 16gb class4 to class10 because with the latest firmware the X10 can read & write with class10 speed...

I'm actually upgrading from a Class2 2GB to a Class 6 8GB, hoping the system overall runs faster so I cant vouch for class2/6 change yet, although I'd question the "cheapest one" for class 2 I found this
remove the space between the "w" since i cant post links yet

Did you guys try getting readings on SD Tools for read/write?
On the original SD Class 2 I got write 1.6mb/s and read 60 mb/s (WTF?)
and on a class 10 which I bought off ebay I got 13mb/s and 17 mb/s !

Sorry if I'm not relevant but how do I find on which class my card is on ?

Use the app "SD Card Speed Test", it will show you the class.

The best possible card is the Lexar microSDHC 32Gb Class 10, but it comes with a price of ~100Euro.
For 16Gb, check if you can find a Class 10 from Lexar, Kingston, Sandisk as these are reputable producers.
Or if the price is right, you can check out a Class 6 or Class 10 made by TeamGroup or A-Data, these are 2nd tier producers.
In the end, remember that not always the fact that is written on the package makes it true.

I use this card and "bang for buck" its the best out there. Never had a problem and read/writes are exactly as stated. In fact, after installing a custom rom, changing to .58 baseband and then adding this card, its made me fall in love with this phone for the first time since I bought it and iv'e had mine since launch (UK). Excellent sdhc card, well worth the money, if like me, you use your phone as an entertainment device.

Class 6 Plus Camera Mod
A while back I stumbled on a camera mod for Build.Prop.. if you get a faster card.. you can adjust your FPS of cam.. I bought an 8Gb class 6 and with the mod it works quite well. So there is ways to improve your software if you want to upgrade your storage.. I got mine at Target with a reader for $20.00. Sure beats the stock 2Gb class 2
http://forum.xda-developers.com/showthread.php?t=922657

Class 10
I'm in the business of looking for one myself as well. From what i have been told your best bet is a class 6 and up. I am looking for a class 10 myself just because the read and right speed are the fastest. Taking pictures, recording video, etc.. always try with class 6 and up for sure.

I have a Sandisk 16GB Class 4 card and just tested the speed:
write: 5.5 mbps
read: 10.9 mbps
Never had any problems with video recording but I can imagine the difference between this one and a class 6 is noticable.

Got an 8GIG MicroSD card, and...

My Hero came with a 2GIG card ( I'm not sure what class ) - it was fine but too small.
After a bit of research, I found that the higher the class the faster the card ( ie class 6 is a faster card than class 2 etc ).
I formatted the new card in the phone.
So I copied all my old card files to my computer, then copied them over to the new card.
Put in the new 8GIG card in my phone and it mounted no problem and I had all my music and photos.
BUT -
As I can see, it seems to be a lot slower than my old card. If I go to my photo album, it will load as a preveiw grid. This used to happen pretty quickly, but on the new card, the grid squares are grey, and then start to load up with the photo images.
Any ideas why and ways to fix this?
cheers all
did you buy the new card from an auction site? I hate to suggest it, but there are a lot of fakes around...

Errhhh, this is actually incorrect.
All the class means is that your card is guaranteed to write at certain minimum speeds.
Class 2 - 2mb/s
Class 4 - 4mb/s
Class 6 - 6mb/s
So, if you buy a genuine class 6 card, you are guaranteed that it will write at 6mb/s but that doesn't preclude it from operating faster than this minimum.
A good quality class 4 will often write at 11 or 12 mb/s, more than double the class 6 minimum. You can expect that a good quality class 2 or class 4 will often outperform the class 6 minimum, whereas as poor quality class 6 will perform far closer to its minimum requirement.
When buying an SD card, don't just look at the class - look for independent reviews. For example, http://www.davidgilson.co.uk/2008/12/follow-up-another-micro-sdhc-card/, which shows a class 2 card running at speeds well in excess of class 6 minimums.
Regards,
Dave
This is another case of the Hero having problems with certain SDHC cards.
The thumbnails for the Album are not being created and stored for some reason, and i can almost guarantee this is what's happening to you.
I've had to go back to using my old 2gb for now, as my 8gb Sandisk Mobile Ultra Class 6 was performing poorly when viewing my photo albums. We're still trying to work out why the Hero is not liking these newer cards...
I'm watching with interest....

How sad, I should have noticed this before. Having read your article, I immediately test my two SDHC cards. The finding changes my fundamental view on class numbers:
Transcend Micro SDHC, 8G, Class 6: 9.1MB
Sandisk Micro SDHC, 8G, Class 4: 14.9MB
Note 1: The Transcend card is from someone who sold me a second hand Google G1.
Note 2: The Sandisk card came with a tiny red reader (Like this), bought in Hong Kong
The speed test is carried out using the Sandisk reader in conjuction with the card benchmark software called "ATTO". To my surprise, the read/write speed of this tiny reader is, amazingly, faster than the internal card reader.
That would be this issue.
Still no real solution yet, but its not an exclusive problem.

Which sdcard ?

I have this great performance and good price too order online though as i went in store and they tried to charge me £50 LOL
Thanks for your answer. This one is good for the hero ?
But what about the class ??? Which is better ?
Hi Guys.
I'm just about to buy a new micro sd card for my hero, as i have heard that usin a good class 6 can improve the speed of the phone.
Basically, I've found 2 great deals, not sure which one to go with.
First, 8gb Sandisk "mobile ultra" class 6, 17 quid on amazon
http://www.amazon.co.uk/SANDISK-MOBILE-MICRO-ULTRA-CLASS/dp/B001U2EQF2/ref=pd_cp_ce_2
Orrrr... 16gb Transcend class 6, 50 quid on amazon
http://www.amazon.co.uk/dp/B0027HUY...ive=7966&creativeASIN=B0027HUYL4&linkCode=asn
Does anybody use transcend, is it any good? Is it guna be as good as a sandisk one?
Thoughts please guys,
Cheers, Dave
I don't know but not a long time ago, i have heard something like that :
A class 2 in sandisk or else = class 6 in kingston or else.
The problem is that i don't remember the brand and the class LOL
I bought a Transcend MicroSDHC Class6 card, anyone knows if its a big diff between class2 and class6?
The read/write speed is different. Here's what I bought: http://www.meritline.com/showproduct.aspx?ProductID=26412&SEName=adata-8gb-microsdhc-card-class4
From Wiki:
* Class 2: 2 MByte/s - 13x
* Class 4: 4 MByte/s - 26x
* Class 6: 6 MByte/s - 40x
The one I bought really did write at 6mb/s which was surprising (although the item description changed to class 4 even though I bought a class 6)
Thanks, glad I bought a class6 card ..
I've bought a 16GB Transcend Class 6 card and it's great.
The class sytem is based upon that the card should read/write a minimum of MB same as the class it is. So a class 6 card should read & write at a minimum speed of 6MB. My card actually is actually faster than this, but it should not go below 6MB on any occation.

Agreed with the Above, however dont base your choice on class only, as there is another thread on here, try searching which a member said that a good brand class 2 (sandisk in particular) outperformed a class 6 ok/crap brand. All the class is there for is to not allow the chip to write any less then stated it does not mean it is faster because its class 6 or class 5
i went with kingston because it comes with a lifetime warranty.

[Q] Class 2 card fast enough?

Is a class 2 sandisk microsd card fast enough to store/view some media and such on it and have decent use with the Atrix?
I have a class 4, 4gb in right now, but I can get a good deal on a class 2 8gb card

that all depends on your usage, some people might see it as too slow, but again it depends on how you feel about the phone read write slowdowns
I use a 16gb polaroid class 2 card i bought for $13.. no problem at all. Although some people might disagree.
I have patriot 16gb class 10, I paid it at 35 euros, speed is really fast 10 - 16mb/s

[Q] Does the Amaze need a Class 10 MicroSD card...?

...to run optimally while recording video/taking pics?
Or can you get by with a lesser class (6) or so?
Just wondering what everyone is using and why.
I have a 32GB class 4 SanDisk and it works great.
Sent from my Energized Amaze
I also have a 32gb class 4 (SanDisk). I haven't noticed any lag when picture taking or video recording.
I was looking up what kind of MicroSD to get my Amaze about a month ago and decided to get this one. Here are some things I picked up while doing the research.
1. Small read/writes usually takes place on the SD cards. Getting a class 10 with good write speeds for large files doesn't mean good speeds with small files.
2. SanDisk is a good brand. Mine is advertised as a class 4 but performs at class 6.
3. If you're looking at the Patriot class 10 microSD, I recommend that you stay away from it. People have been reporting errors with that card on Android devices. Patriot said that they've fixed the issue, but there are still a lot of bad cards floating around. You never know what you get.
4. If you do go with SanDisk, get it from a reputable dealer (not eBay). There are tons of SanDisk counterfeits.
Thanks so far guys - exactly the input and information I was seeking.
I have a 8g Class 6 from my G2, and a 4g Class 10 I paid $6 for to test out - both by Transcend off newegg.
Will get something with more capacity soon, and was wondering which direction to head.
I just got a patriot 16gb class 10 about a week or two ago from newegg for $10 ($20 with a $10 rebate) and it's awesome. I mostly notice it when transferring files (videos and music) between my phone and laptop. I had a 16gb class 6 ADATA before this one, but it was only 12gb cuz I originally used it with my G1 and had it partitioned.
My wifi downloads have been quicker lately, but I'm sure that's just coincidence. Anyways, good luck!

Higher classes are more prone to errors. With the bitrate phone records hd. A class 2 is way more than enough. Go with a class 4 SanDisk. Higher classes have better sequential good for recording movies etc. Lower classes have better random read right and less prone to long term damage. The higher class you go the more risk you'll have of getting corrupt data etc. The only benefit of higher class is better sequential write speeds. ALWAYS GO with sandisk

If I had known this sooner, I wouldn't have invested in a 32GB Class 10 disk (not sandisk). So far, I've had it crash twice, and had to reformat every time. It's rather annoying and you do lose all your data; so for those out there still considering it, please add this to your factors of consideration.
16 GB class 6 SanDisk. No lag. No problems.

Always buy sandisk. I have not heard of any sandisk going bad but heard of all other brands going corrupt over and over. I don't believe sandisk has a class 10 or class 8. They always stick to stability and quality and is worth the price. Besides a class 4 sandisk usually outperforms a class 6 or 8 of other brands. Search for my posts regarding memory topics in accessories I talk about sequential read write and random read write and how the bit rate our phone records video in HD is waaaay below even a class 2. a good balance of sequential read write (long files such as videos or movies) and random read write (gigs of small files) is either a class 4 or class 6 if i was going to go allout I would get the new 64gig card made by sandisk for mobile phones. I think its a class 6

sandisk doesn't make class 10's or 8's, but It could be imported or something or maybe even a knockoff...the only way to make sure you have a sandisk is to call them and ask if they actually sell class 10, to my knoweldge the fastest microsd they sell is a class 6. can you point me to their webiste or somewhere, I am very interested. they do sell class 10 SD but not micro sd. I am very curious where you got this and how sandisk is actually replacing this...I have looked all over for a class 10 micro sd.
you can buy it at newegg: for 120 http://www.newegg.com/Product/Product.aspx?Item=N82E16820171571
or on their webiste for double the price lol: http://www.sandisk.com/products/mobile1-memory-products/sandisk-ultra-microsdxc-card
don't forget to increase your read ahead cache for the sd interface too. 2048K should be the optimal size.

32 GB Memory Card

Which is best 32GB memory card for Neo V..
n is the Phone fast with 32 GB card or getting Lagged??
i'm not getting any lag with my 8GB (class 4) card. 32GB will do good
Let me give you an advice.
To the best of my knowledge a 32 GB sd card will need more power to work which means it will draw more power.
Also it depends from whom are you gonna buy it?
Sandisk? (if it is sandisk then BUY IT)
Also at the store ask for its class.
Just something about classes.
A class 4 card IS always going to give you at least 4mb/s write speed.
Although this is not always true.. (i bough a Kingston class 4 16GB for 8.5 euro XD and it is working fine but it mostly runs with 3mb/s it is slow but it was the cheapest and bigger)
The higher the capacity of the sd the slower random read write speeds.
So if you are planing to move many apps on your sd i do not recommend anything class 10 like.
But if you mostly need it for gaming/music/movies then for CLASS 10
Oh and always but sd cards from the web they are way cheeper than from stores.
(my Kingston from a shop costs 16Euro -mostly like every card 1Gb=1euro)
Buy a card with a high speed class.
Take min. class 6 or class 10.
Buy a card from a well know manufacturer like kingston , San disk or Samsung.
I use a 16 gb Samsung class 10 and the write speed is fantastic. 12 mb/s.

The answe is yes and no.
What 32GB ?
A 32 gb class10 sandisk wont slow it down.
A 32GB CLASS 4 KINGSTON WILL SLOW IT DOWN
it depends on the cards class and company.
a kingston class 10 VS sandisk class 10
would lose sandisk creates very fast sd's
If you are willing to pay a lot of money then buy sandisk class 10
IT WILL BE EVEN FASTER THAN WHAT YOU HAVE.
It depends on everything!.
Also android doesnt use the full potentional of the sd card.
You will need to root your phone and use an sd booster app to unlock your cards MAX SPEEDS!
For 32gb class 10 is must. Otherwise video recording, playing HD videos etc will lag.
I use 8gb class 10.
toshiba 32gb class4 no lags so far
Exchange of files between the computer and the phone affects the importance of speed

Previously used a transcend 16GB class4, the speed difference isn't that much, but you'll save a few minutes when making a CWM backup. (I went from 9 to 6 minutes).
But it was just €3 more than a class4 card, so worth the price.
My brother use Sandisk 32Gb class 4 for his MK16i (x.Pro)
Everything is working very well
