I like the low peak electrical current draw
I am using it in a DIY camera project, writing video to the flash drive at 30Mbps. I have tested it to the full capacity of the drive and it works well.
It's only USB 2.0, so that will put an upper limit on its speed, but it feels pretty quick to copy a few gigabytes of video. I didn't buy this for speed. Unless you have a specific reason why you need a faster drive (e.g. copying many gigabytes under time pressure, or running software directly off of it), this drive is probably fast enough for most purposes.
The small size opens up possibilities to use it in places where a normal-sized flash drive would stick out and get in the way or get knocked and damaged. For example, you could leave this plugged into an MP3-capable stereo system and in a lot of cases it would end up being flush with the surface of the stereo, or else nearly flush.
I didn't need a small flash drive for my purposes, but I had a hunch that small size might mean low power consumption, and I did need a drive that would draw a low peak electric current, due to the particular power supply arrangements in my camera project. And yes, this drive does have a relatively low peak power consumption.
This low peak current characteristic could also be useful if you want to plug the drive into an unpowered hub or the end of a long USB extension cable, as some other drives might struggle with that, but it is not a panacea.
