Some surprises 1

Enchanted by design. The key seems well protected by the butterfly flap that there is no risk of losing and seems sturdy. Compact, so no worries for using the neighboring ports even if they are close enough.
The key is provided with a control LED which is not always the case with USB 3.0 keys. Too bad this LED is visible only one side.
Side performance:
1st test scripts:
23 files totaling 6021 MB 6 min at an average transfer rate of 16 MB / s, despite a poor peak flow in excess of 45 MB / s! In fact it has a kind of reflection time of several seconds between each file.
I realize that the key comes formatted in FAT32, so I decided to try the NTFS
2nd test of writes (NTFS):
My 6021 MB are copied in 2 min 40 ', there is much better and not bad at all! An average rate of 37.5 MB / s with identical peak flows in the 1st test but without the waiting time between each file.
This deserves to be indicated on the packaging.
