Card reader

I've been impressed with the Sandisk 32GB Class 2 microSDHC card so far. I bought it with bulk packaging, which means it came in a small plastic clam shell case slipped into a little plastic envelope. There were no included adapters.

I'm using the card in my Android Nexus One cellphone. I've used a benchmark app on the phone to gauge performance of the card, and it is doing about 5MB/sec writes and 9MB/sec reads. This is with settings at 10MB test data size and 8KB write unit size. I saw similar write performance when the card was mounted on my PC via a USB 2.0 card adapter. These numbers indicate it's performing somewhat better than the minimum guaranteed for Class 4 cards, which is great. I'm coming from a 16GB Class 6 card and haven't noticed any performance hits, so far.

Just a caution for you all, if you intend to use these chips for camcorders or cell phone video recording, make sure the chips are a minimum Class 4, or ideally Class 6 or 10. For file storage or file transfers Class 2 chips are fine, but I would not use Class 2 cards on newer devices that require a faster SD or microSD card.

Bottom line first: I have some of these cards (bought because of the price and even I can't resist a good deal on cheap storage), but also Class 4, 6, and 10 chips. (In fact, my review of this chip is based on owning about 300 chips (or cards if you prefer and using chips back in the days when 2 MB chips were $90, yes, I said "megabyte" :)

The caution you have to take is that if you are getting these chips as a primary or principal card, keep in mind that its speed rating may be insufficient for use on SOME of your devices. (E.g., some cell phone camcorders record video fine, others require a faster chip, such as Class 4 or 6)... Read more

I bought this to put in my new Samsung Focus Windows Phone. This card has not been certified by Microsoft to work with the operating system, but I have had no problems after a week. I didn't use the card in any other way before having the phone format it. The card performs well and I am sure that is would work admirably in a more tradition sense. And one more thing, the price was excellent for a 32GB card.
