This thing is crazy fast. I have two of the 8gb ones from a few years ago. They kinda let me write to them at about 8000kbytes/s. This thing when I throw 300mb files at it moves them at 18500kbytes/s. I can't get a reading for my mp3s because it's going that fast I can't read what it says. I'm reading 300mb files at 32850kbytes/s from the stick to my hd.
I ordered this last night about 5:00 and it was delivered this morning about 10:30, so that was crazy speed too.
There are a lot of fake Corsair USB pendrives about so I checked on their web site. Play.com is listed as a supplier, so you can buy with confidence. I don't really need another one, but I may just get another for the sake of it.
The guy above getting 4.3 k speeds must be doing something wrong or it's faulty because that's half the speed of my old ones. Maybe he has it connected to USB1 instead of USB2.
Very Very recommended.
