Best price I can find for an excellent brand of 32gb Micro sdhc card. If
you know of a better deal I'd be happy to hear about it. Sandisk doesn't
specify class on the non-Extrume/non-Ultra drives, but users report
obtaining speeds faster than Class 4:
"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. "
Another:
"...I also used a benchmark app called SD Tools and it's reporting write
speeds at 7MB per second and read speeds at 13.8MB per sec. That's much
better than what you can expect from most Class 4 SD cards."
"Card came with a formatted capacity of 30.1 GBs, and so far write speed is
averaging about 4.5 MB/s! "
Sounds like class 4+ to me, but YMMV... Also, don't order from shady
sellers, always buy from Amazon direct or when not possible check seller
feedback first!
