Very fast read speeds; reasonably priced

Average write speeds (typical for class 2 cards); buying the bare card yields just that

Sandisk 4GB MicroSDHC Memory Card with SD Adapter

Works great and amazed at how 4GB can fit in such a tiny tiny little thing as big as a finger nail. My only fear is losing it because its so small. Thankfully, it comes with the case so as not to lose. Good stuff!

Exceptional!

Bought it for my BB Curve and got it the day I discovered there was an official release of 4.5 for the 8320 from Orange in the UK and TIM ITALIA. So I am now rockin an 8320 with 7.5gb of flash memory. Can't beat it!

Small size; high quality; basically everything we have come to expect from flash memory

None whatsoever
