Having already had a lot of USB keys, I hope to have found one that held on time. Indeed, many key does not hold water and buggent after a while.
So I decided (long live the amazon lists) have a good key with a good capacity and above all, with a good flow. Here we are in compliance with the rates announced by the brand.
After the first tests, I turn to 104mo / s for the copy of a video of +/- 1GB usb3.
Aside from that, it seems small but it's still a USB key, a fragile thing.
It fulfills its role very well: good capacity, good price, RAS speed.
ps: not 5 stars because perfection does not exist
