    SanDisk Flash Drive Review

    This is great small Flash Drive. It has both USB-C and USB regular fittings. Works fast and it's almost TOO small (it's about 1/2 the size of a regular flash drive, see the picture); I need to be careful not to lose it in a pocket. The right amount of memory size and a good price. I used Best Buy Rewards money to purchase it so it was a nice deal.

    Metal housing and high quality

    This drive is very high quality with its metal case, and having both USB formats makes it very versatile. The size is small and the rotating input (for USB 3 or C) has a catch that holds it in place while in your pocket. Also got BB to price match so it was a great deal for the 256GB drive.

    Exceptional product

    Very durable body and lots of space for files. It transfers fairly fast. Does get a little hot when transferring many gigabytes but that’s to be expected and hasn’t been any kind of issue.

    Works great, love the design! Gets hot during use.

    This is currently my favorite flash drive, and it works great. I like the thin USB-C design, which allows it to be used on a phone or tablet, even those with a case. I also like the metal housing for its durability when switching between USB and USB-C. But I think the metal case is also the reason It gets hot during data transfer. When watching a video stored on the device, it also gets hot. The heat is a little concerning both in regard to possible longevity issues and unintentional skin contact that would be hot enough to cause a reflex reaction if it touches a sensitive part of an arm.

    Convenient!

    Really impressed by the tiny size and large storage space of this flash drive. Makes transferring files between phones/tablets much easier. The transfer speed is also great.
