Last month at the 2009 Consumer Electronics Show, SanDisk announced their new 16GB "Mobile Ultra" memory cards in the microSDHC and Sony M2 formats. The microSDHC card is rated SD class 4, which means that under perfect operating conditions that the card will feature, at minimum, 4 MB/s (26x) write...

I did not think it would fit in my cell phone. Do to the fact I have been just buying from AT&T. The microSD fits and works great. I have yet to use the larger attachment.

Cost effective SD but write speeds are not fast enough to handle Full HD, standard HD and slower are fine, but it errors on Full HD.

I bought this 16GB microSDHC card to increase the storage capacity of my SanDisk 4GB MP3 player. 4GB is just not enough for all my tunes! It has worked just fine with no problems whatsoever. Note that this is a Class 2 card, i.e. on the lower end of cards in terms of speed.

I bought one to use with my Galaxy S4 and it works very perfect. It is very fast and has a big capacity to store everything I need.
