    Says its faster

    They say 3.1 flash drives are faster than 3.0, so I bought one. It sits practically flush with the edge of my XPS 13 laptop so I don't have to remove it when put it in its sleeve. I use it to back up my important docs without having to drag out another external drive when I'm on the road. I hate having these documents on the cloud. One problem is that it heats up when it's doing heavy transfers. I had another small USB drive like this before and you really can't avoid it because there's nowhere for the generated heat to go. So I'll take it out right after and hold it between my fingers to dissipate the heat. For 128 GB, it's got enough memory for me to be just drop stuff on it at will.

    Permanent Flash Solution for Car Entertainment

    We needed a flash drive so the kids could watch movies in the car entertainment system. I used a typical sized flash drive and it kept getting bumped, kicked, etc. and eventually broke. This low profile flash drive is exactly what I needed! There's nothing to bump or kick you can't really even notice it's there but it is and it holds a lot of movies and has made my family car rides very peaceful! Thank you SanDisk!!!

    Small But Big

    Nice, little drive with lots of space. I like how I can keep this in my laptop all the time. When formatted I get about 114 GB of storage. Speeds are pretty fast as well.
