    SanDisk delivers a solid flash drive with 128gb and USB 3.0 connectivity. This is great for photo, music, and video storage. I like the notch on top so you can run a cord through it and wear around your neck if you like. It came in handy for me to store 2 stories that contained 42 episodes, took to a printer and plugged right in.

    I bought this 128 GB USB drive for my home backup server. It's a PogoPlug running Debian OS with 128 GB drive mounted as additional storage. It does great job for what I intend to use it for. In other words, the R/W speed supported by it more than serves my purpose. I would definitely consider purchasing same model with higher capacity in the future.
