for that price, it's great (bought 15 ..) well, it's a basic USB key, so not too original design (hence 4 not 5 stars ^^) For transfer rate, it's the same as any other key, nothing special what.
USB 3.0 Key unadorned (standard cap and no special software which we have often not needed). Recognized immediately in both XP Windows 7. Flow rates recorded in writing 8Mbits / s USB 2 and 20Mbits / s in USB 3. fluid film playback smoothly. In short
