San disk usb
||Posted .Owned for 2 months when reviewed.I love to keep some usb drives on hand for different reasons and in different sizes. These are San disk ones which I selected specifically as the update for my car sometimes will not work if you download on certain brands of usbs. Found that out the hard way. Lol. Then called the Chrysler and they said it could be the brand of usb. I switched and it worked. Strange but true.

SanDisk Ultra 512GB USB 3.0 Flash Drive
||Posted .Owned for 4 months when reviewed.I needed a large capacity USB flash drive for backing up a significant number of important files on my laptop rather than relying upon my cloud storage to do so. The USBA drive is quick and offers 512 GB of space, which is great.

Great for the money!
||Posted .Owned for 2 weeks when reviewed.Great usb. My son decided to get this one which has plenty of space. I gave him $20 dollars extra so he could get the bigger space. He was happy to have not this one instead of the smaller one. For the price difference this made more sense.

Awesome flash disk
||Posted .Owned for 3 weeks when reviewed.This sandisk flash disk is perfect for me to backup all my important data including pictures, videos and music. It is super fast and I can save files onto it crazy fast and access it so much faster than I could a portable hard drive. Also, it looks so cute and nice - I like the feel of it very much.

Reliable drive and good size
||Posted .Owned for 2 weeks when reviewed.I buy a lot of flash drives for use with certain things. Bigger is better in most cases as I can then put more things like video files on them without having to use up bandwidth when streaming. I've had good experiences with SanDisk flash drives and got this one on sale, which made it an even better buy.

Q: QuestionCan I load movies on this drive and play them on my TV and Firestick or do I need to format the drive?
Asked by Dee81.
- A:Answer Hi, please be informed that all our USB Drives of 64GB and above capacity are pre-formatted in the "exFAT" File System and most of the TVs/ Media Players do not natively support reading USB Drives formatted in the exFAT File System. If your TV/ Firestick supports reading and playing movies stored on USB Drive that is formatted in the exFAT File System, then you can use this USB Drive with your TV/ Firestick, otherwise, you would need to format the USB Drive in a File System supported by your TV/ Firestick. If you wish to get help from our support staff for the same, please feel free to contact SanDisk® Support at 1-866-SANDISK and we would be glad to assist you.
