Review: High quality handy storage and transfer device for phone to computer - Super handy device. Much easier and faster than trying to transfer photos from my phone to my computer via a data USB cord which is quite slow and cumbersome. This is also tiny and easy to keep with you. At 256 GB this will hold a lot of photos and videos and makes it easy to share, copy, save to computer, or just store your photos so they aren't filling up your phone storage. I've always had good luck with SanDisk products and most all of my flash drives, cards, and readers are SanDisk. This is very sturdy, well made, and the spinning cover is perfect for protecting the end and easy to switch between the C and the A USBs. Well worth the price.
Review: Very Convenient and Wonderful Quality - Works well, easy to use, and it's very convenient to have both USBC and USBA on the drive. It's a good storage amount for the price. Overall, Fantastic quality

## Questions & Answers

**Q: I bought one 64gb and it has printed the same but it actually has 32gb when i looked into my windows system. why is it so?**
A: Have you looked at how the flash drive is set up? There's an outside chance that it merely has 1 primary partition set up as 32gb and 'unallocated' space that is the other half of your storage. For this you'll need to look at the drive with Disk Management in Windows to see how partitions are configured.

**Q: Is the usb-a connector backwards compatible with usb 2.0 ports?**
A: Yes, it should be but without the same transfer speed as 3.0.

**Q: How many pictures will the 256gb sandisk hold?**
A: A 256 GB Flash Drive will hold roughly 150,000 pictures. Or, it will hold about 50,000 pictures and 35-40 hours of movies together. At least according to my math from investigating data about this.

**Q: Where is it made?**
A: Mine says Malaysia
