Have the memory stick as boot media (Linux) for my NAS in use. The boot process is carried out quite fast (about half a minute), install software, etc. on the stick as quick runs. Therefore I am satisfied with the speed. (Previously, the "old" with a SanDisk Cruzer it took a good five to ten times as long.) The stick is hardly out of the PC case and is therefore not out when the NAS shifted in danger, or is totally cleared up. A second is a backup / system recovery stick in use. Only an attachment of the cap or a small labeling options would be beneficial (for mobile use of the Recovery sticks or to distinguish multiple sticks) Conclusion: Very satisfied, so I have already several.
