Thanks for the info.
[General Accessories] wolfen69:
I think too much is being made of the speed issue. Just buy any decent brand name class 10 microsd card and move on with your life. You're not going to notice any difference in the real world.
[General Accessories] bogdan1980:
You will notice any speed bump, and also if you have good chips in an card you will not receive formats, card dissapear, card died, etc, in an single word you will get stability.

I hate Samsung for some things they make, but at memory, ssd, panels, they are the king.

50/50 on my luck with Kingston

Just want to share my experience. I purchased a Kingston 16GB model SDC4 2 years ago for my Samsung Admire. Still going strong, quite bulletproof. Got the 32GB version to put in my LG F6, and it died 10 days later. If nothing else, I'll yank the 16 and use that. I'll just have to have a little less music on it...

Raspberry pi SD cards (that work!)

Sorry if this is off-topic...

Does anyone have any information on which SD cards are *known* to work on Raspberry pi?

Do class 10 cards work, and do they work faster than the older class 4 on the pi?

I use a Class 10 SanDisk 32GB microSD card in a microSD to SD adapter with my Pi. Works just fine.

Any card will do, though. Higher class is a bit better for running XBMC, since sequential read and write is more important for media playback.

[General Accessories] CroWarrior:
Hi,

I plan on buying new 32GB SD card, and here in shops near me (Zagreb, Croatia) the prices are really similar (the difference is below 0.5$), so I am not sure what to buy, concerning the post stating that class 10 can be worse than class 4.

There are a lot of cards, and I focused mostly on Transcend/Kingston class 4/10 32GB cards. Which would be the best quality card?

I would use it in my smartphone, mostly for storing music/videos, captured photos and videos and a few applications moved to sd.

I have Zenfone 5, if it means anything. :)

Thank you in advance, I hope I am not off topic. :)

EDIT: And yes, Kingston UHS-1 is about additional 8$, but I am not sure if it will make any difference...

Flaky Samsung EVO 32GB Class 10

After several days of use and two cards, it seems that this card is too flaky to be reliable - at least in my Samsung Galaxy Legend (SCH-I200PP VZW). The phone keeps losing track of it, like the file system unmounts but leaves the mount point.

Grabbing a 32gb lexar class 10 from bestbuy tomorrow. Will see how it goes...
[General Accessories] dss4me3:
I am upgrading my HD2 to Windows Phone 7 and the SD card compatibility is a must. In order for the card to perform properly you must have good random write speeds. If not, you will experience freeze, lag, random restarts, and overall headaches with WP7.

So, I did some research and found that Best Buy is selling PNY cards that are WP7 compatible.

Then after reading this thread, I saw that the sandisk 32gb class 4 had great random speed results, so I decided to test both and my old patriot 16gb C4 to find out which card I would ultimately use as my HD2-WP7 SD card.

Here are the results: (note all cards were formatted prior to testing)

Patriot Card:

It is obvious that the Patriot Card's random write speeds are ridiculously low, so this card is going to be re-formatted and will replace my 2gb card on my point & shoot camera. It scored great an sequential speeds (good for cameras), but as it is essential for WP7 to have good sequential write and read speeds, this is not a good choice for WP7 Phones.

PNY Card:

This card did very well. Scoring only higher to the Sandisk in sequential and 512K write and slightly higher (almost negligible) in 4k and 4kQD32, in the 1st run.

Sandisk:

This card (in my opinion did best) scoring higher in all read speeds, lagging only in sequential write speeds and 512K yet higher in random write. Being that random clocking is of most importance to WP7, I think that Sandisk 32gb class 4 will be the SD card I choose for my WP7 Windows Phone.

______________________Conclusion________________________________

Both the PNY and Sandisk cards will work great in WP7 Phones, but I chose the Sandisk because it has higher read speeds. So that means once the program or data is loaded it will be able to read it faster. The most important factor for my decision was that the PNY costs 89.99 plus tax at best buy. The sandisk runs for 69.99 and I did a price match with a Comp USA printout and purchased the card for 59.99 plus tax. (30 dollars cheaper)

I highly recommend that anyone who is planning on switching to WP7, test their cards first with Crystal disk. If your random Write speed is low, do not install WP7 until you get a better card.
[General Accessories] chongyixiong:
Thanks for the information, it was really helpful.

Now I know why my 1 year old Sandisk Class 4 8GB microSD seems to be even faster than the recently purchased Transcend Class 10 16GB microSD.

Until today, I've never seen a Sandisk MicroSD Class10 card though, not necessary perhaps?

so for the Xperia PLAY, which is better, SanDisk 32GB Class 2 or Class 4?
[General Accessories] cajunflavoredbob:
It's not a big difference between Class 2 and 4 in terms of performance or price. I doubt it will matter much to you no matter what you use it for. Mine is a SanDisk 32GB Class 4. The consensus seems to be that lower class numbers are better for running apps from the SD card (Apps 2 SD) due to higher random speeds.

[General Accessories] twospirits:
I bought this that very same day and it finally came in today 15 days later.

I tested it using both the CyrstalDiskmark as well as with h2test2 (which ebay recommends (helpful when doing a dispute for those sd cards you buy on ebay and end up not being as advertised).

With h2testw the results are..

Test finished without errors.

Writing speed: 5.55 MByte/s

Reading speed: 16.5 MByte/s

With CyrstalDiskMark the results are...

Seq Read: 17.97

Seq Write: 6.130

So although it takes forever to get the card (for a while I thought it was a fake coming from China) the card is a class 4 (almost a class 6).

I am happy with the purchase. (Especially considering that I bought 4 of them.)

[General Accessories] kitaeshi:
i thought class10 is more faster than class4?
[General Accessories] L2_n19h7m4r3:
Class 10 is the fastest around... for now.
[General Accessories] cajunflavoredbob:
It is the fastest for sequential speeds. Lower class cards have better random speeds. Random speed is better for application launching, while sequential is better for file transfers and music/video. I use a lot of applications on my device (more so than I listen to music or watch videos), so I prefer lower class cards for their better random speeds.

It all boils down to what you as a consumer need. WP7 users should always use Class 2 or 4 cards only. WP7 NEEDS high random speeds due to the way it bonds to the SD card.

[General Accessories] garychencool:
so basically for fast android app usage where it needs bits of info, get class 2, 4

for reading/writing stuff like movies/other large media, get class 6, 8, 10 for the sake of speed as it does into the card and being read by whatever media app you have.

Hm, that helps a lot, but I need the best of both worlds, so class 4, 6, 8...

Very helpful thread in explaining the differences in the card class speed relating to phones. I ended up going with the Lexar 32GB Class 10 microSDHC. Got it from amazon for only $47.99. Still waiting for it to arrive.

Hey, I planned to buy a 32gb microSD card, so I read some articles about it but still not sure what class should I choose.

I have Xperia neo, with its default (Samsung) 8gb 2class sdcard. I use the card for apps, music, and for video records too. So I often move large files, eg copy music, movies and I use it for system files, so the quick access is almost the most important. The phone can record 720p videos, and it creates quite large files, and it's quality is important too.

As I looked the test the brand is SanDisk (in normal prices..), but I dont know which class would be the best for me.

Can you help me?

I suggest Class 4 and upwards, ideally Class 6 since if you're playing demanding games which have data stored on the SD Card you need fast access.

If you don't want any compromise go for 32GB Class 10. ;)
