    If you need a Flash drive with a lot of storage space as I did, this 256 GB Flash drive is a great Flash drive. The USB 3 drive is much faster than the USB 2 USB drive which is nice. What made the purchase even better was that I got this item on sale!

    There smaller SanDisks; however, the smaller ones are "too small" for those of us with Arthritis. Stay with this one for easy use.

    I purchased two of these after years of past experience with SanDisk usb drives. I use one mainly for work, which requires me to use on many computers. The other is used by my daughter for school. It is fast and reliable. It is very light, yet feels sturdy.
