    Originally went in looking to buy a portable external hard drive to carry about 50 gigs worth of data. Found out this flash drive was on sale for a very good price of just shy of $15 and couldn't be happier. Way faster than old USB 2.0 flash drives with a big enough amount of space for most data needs. Plus the red shell was nice.

    Purchased it to save some data and pictures. Its smaller and more convenient than carrying around the external hard drive, just to save pictures on when on vacation.

    Perfect size for my system backup and the color red reminds me that I have very important content on it so I am not tempted to use it for anything else.
