Just don't go higher than a class 6 (So I've heard). It'll still work, but supposedly our phones can't handle anything higher...so even a class 10 would only operate at class 6 speeds.

I run a ADATA class 10 8gb SDcard and it runs the same in the phone and my computer (20mb/s). Just dont bother spending more than the cost of a class 2 when u buy one. I got mine on a killer deal with newegg.com but it didnt increase anything noticeable. All class 10 means is a minimum transfer speed of 10mb/s which sadlly most all class 2 SDcards can do anyway.

Conclusion: Buy with cost in mind only a professional photographer needs the expensive ones.

I paid more for a 16gb Class 10 card but figured even if the Phone couldn't fully use the additional speed when I plug it into my computer to transfer files it will take advantage of the extra speed.

Class 10 does not mean 10mb/s it means it is 10times faster than a standard uSD (standard uSDHC is class 2). Actual benchmark speeds for a class 10 is well over 40mb/s thats compared to 8mb/s for a class 2 card. Something to think about when your backing up large amounts of music files on larger cards.

Please don't spread misinformation Class ratings for SD cards have an industry Standard and you don't seem to be aware of. Class ratings for SD cards ONLY INDICATE MINIMUM SPEED. That is a fact. It does not have anything to do with top speed or even any kind of benchmark you want to toss out.

So before you go spouting off about stuff you haven't even researched go do some reading or at least google it first.


A Quote from the SD Association's website the Official governing body for SD card ratings.

Speed Class Rating
The Speed Class Rating is the official unit of speed measurement for SD Cards, defined by the SD Association. The Class number represents a multiple of 8 Mbit/s (1 MB/s), the least sustained write speeds for a card in a fragmented state (Class 2, 4, 6) or the minimum non-fragmented sequential write speed (Class 10).

These are the ratings of all currently available cards:

Class Speed
Class 2- 2 MB/s
Class 4- 4 MB/s
Class 6- 6 MB/s
Class 10- 10 MB/s
Even though the class ratings are defined by a governing body, like "?" speed ratings, class speed ratings are quoted by the manufacturers and not verified by any independent evaluation process. In applications that require sustained write throughput, such as video recording, the device may not perform satisfactorily if the SD card's class rating falls below a particular speed. For example, a camcorder that is designed to record to class 6 media may suffer dropouts or corrupted video on slower media. On slower class cards, digital cameras may experience a lag of several seconds between photo-taking, while the camera writes the picture to the card.

Important differences between the Speed Class and the traditional CD-ROM drive speed measurement ("?" speed ratings) are that speed class:

1. may be queried by the host device;
2. defines the minimum transfer speed.


(Note item #2 at the bottum)

This is not to say they can't go faster than their Class rating lots do. But there is not a way to know till u use it since they are not verified by any independent evaluation process. If u think marketing is honest your crazy.

I've had a 32GB MicroSDHC (Class 10) card in here since I bought the phone. Works perfect. I got the phone when it first came out - it is the original model.
