Alas, I admit I was a little disappointed. The read speeds are quite good, 57 MB / sec, but not at the promises of PNY (up to 115 MB / sec). By writing against it is very average, only 9.6 MB / sec. My tests are not intended to be comprehensive but compared with my USB 2.0 devices, improvement is not obvious in writing. Fortunately the price of this T3 Attached is attractive and the price / quality ratio is good.
Regarding ergonomics and design, again the picture is mixed. The key is metal, very solid, it will not let you. Nevertheless, it heats if it stays connected longer. More annoying, although it is planned for use keychain, it is provided without ring or strap, damage ... Attention, you will absolutely add to it a cord before using, because once connected, it is really hard to remove because its surface is slippery. I had a heck the 1st time. Good point: its low width not risk dobstruer a neighboring USB port.
In short, a robust key, rather pretty but with some minor flaws happily. This remains a good product that I recommend.
