    Laptop Takes My Files As Hostage!

    I was frantic. My laptop decided to take a nap. Sometimes, it woke up. Sometimes, it slept all day. I needed my documents I stored on it. The Geek Squad suggested I purchase the USB drive. I am glad I did. My laptop decided towake up one last time and he assisted me with transferring all of my documents to my USB drive. Suggestion: Don't say anything important on your computer. It might costs you more in the end to retrieve it. Lesson learned!

    Works good - needs a string to better keep track of it. I like that it has a (very) small space for writing the contents of the drive on it or a name. I would prefer the jump to come in lighter colors or white.

    This is easy to use and excellent for storing documents and pictures. I had hoped it would store my music playlists and it doesn't. That might not be ITS fault, maybe my lack of knowledge. I would definitely recommend it for those things I mentioned.

    It’s a flash drive. It stores stuff. So far, it hasn’t deleted all my photos or blown up, so I’m pretty satisfied.

    Amazing size for the capacity. Price is a bonus! Back in the day the same capacity was 4x the cost and not a flash storage. Technology has come a long way. Really enjoy this for backing up everything important.

    The SanDisk Ultra 512 GB USB 3.0 Flash Drive came to the rescue after a Migration tool failed to transfer all my files to a new PC. Saved me hours of aggravation. Be sure to reformat it to NTFS instead of the default FAT32 if you have large files.

    Excellent flash drive. I store my You Tube videos, which range from 1 min up to 26 mins long each. It has held over 110 videos so far with room for many more. At 512GB I can only image how many documents it can hold. I highly recommend this flash drive.
