    If you have a USB 3.0 capable computer, than you need a 3.0 flash drive. These are so much faster then 2.0. If you move large files often, than you have to get one of these! Money well spent!

    I use it to store files that I need to work on several computers. Since my connections to one drive are not always available, this is a handy way to keep my files available. Works great.

    I've purchased many of this exact SanDisc Flash Drive over the years, with various capacities. I am ALWAYS happy with them and even after several years my large digital files remain intact and uncorrupted. These thumbdrives are simple to use and give me peace of mind when it comes to back-up.

    Great, economical product! I got a new computer, and this made transferring data so easy - no signing in with a password and waiting for slow down loads - just load up files to the thumb drive and download to the new device. Painless.
