I did some benchmarking/performance testing to compare this with the equivalent Samsung 128GB USB 3.0 Flash Drive Fit (MUF-128BB/AM). In a nutshell, it performed identically. Both drives warmed sligtly to the touch, but never became more than slightly warm, even during extended write operations taking over 10 minutes.
One thing worth noting is that the Samsung flash drive does not seem to include a status indicator light, whereas the Lexar incorporates what is essentially a room-illuminating flashlight, in the form of its blue LED status indicator light. Seriously, if you are using this drive in a dark room, it will illuminate the entire room with blue flickering. For some, this may be undesirable.
Update on 2016-08-20: It may also be worth noting that the Lexar drive does not include a hole/slot/notch suitable for attaching a lanyard. The Samsung alternative does, albeit a very small one (a bit challenging to actually get a thin lanyard attached to it). Given how tiny these drives are, lanyards can be a useful addition to them.
