    I love that I can put all my files, music, pictures, and videos all on one flash drive. It is very convenient; I do not have to carry several flash drives with me all the time...just one. Great product by SanDisk and still have a lot of room to add more files.

    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!
