Please note that this is a key EXTERNAL not a disk drive and AMOVIBLE

I did not give it 5 stars because the product description does not specify that this key will only be seen as an external drive instead of a removable disk. This detail is important because some functions that expect to find a standard USB key does not work on an external drive and vice versa! Outside, it does not seem possible to see this external drive as a removable drive and I think it's a gap that limits its use. This feature should have been reported in the product description. So the key is actually an SSD drive with a USB 3.0 interface. Also I read in the comments from other customers that this removable disk could not be used (or at least not easily) to boot a PC, I found quite a pity. For the rest, the performance is good, especially on large files and mechanically, no worries for now with the retractable connector that works very well but it's true that any plastic device will perhaps not not last long, so use with caution and without forcing ...
