I have the Corsair 64GB Stealth Survivior added myself, because I was looking for a USB flash drive with high capacity. I use the stick mainly to USB 2.0 ports. Here, the read and write speeds are ok. For USB 3.0 ports but there are cheaper and faster drives. I drag the stick almost daily rum in my pocket with me. He does not disturb me. The outer shell is dibasic, and actually indestructible. However, I have breaks whenever you plug in to your PC afraid that the stick because of the long stick very wobbly seated in its socket. Here you should copy the concept of shell. However, by and large, I am very satisfied with the stick. For me 4 stars!
Update 31.08.2013: I have the stick still in use almost daily. The fear that the stick breaks has not materialized so far. The stick funktionniert still.
