32GB MicroSD for AT&T Fusion Smartphone

I ordered 2nd AT&T Fusion smartphone GoPhone for my wife and she is ok with it. I showed her that she can play "Angry Bird" game on her phone but she found that game to be boring. However, she wanted to watch movie on her phone instead of her mini 8GB IPod. The GoPhone comes with 2GB MicroSD and that is not enough for her movies. So I need to buy bigger MicroSD for our smartphones.

Coincidently, I noticed 1saleaday.com had a great deal on bunch of MicroSD cards. So I purchased 2 SanDisk 32GB MicroSD for our Fusion smartphone. This SanDisk 32GB MicroSD is class 4 and from what I researched, it seems class 4 is enough for watching movies directly off SD.





Here are some other things I learned from my MicroSD purchase:

• MicroSD is same physical size as MicroSDHC.
• For larger memory size, MicroSD become MicroSDHC (where HC mean high capacity)
• Class represents minimum write speed.
• Read speed is expected to be same as write speed
• class 2 : speed 2MB/s
• class 4 : speed 4MB/s
• class 6 : speed 6MB/s
• class 10 : speed 10MB/s
• The high class MicroSD is mostly required by the DSLR camera but for typical smartphone and tablets, class 4 should be enough.
