Pros: Fast enough to work in my Video Camera.

Overall Review: highly recommended

Good Price, Fast Shipping. Read and Write speeds Very Good.

Claims "Write up to 15X faster than standard USB 2.0 drives" I guess that's true if you compare it with a 1.1MByte/s Write speed drive. USB 3.1 at USB 2.0 Write Speed. is what you get.. Sustained Write is only 16MByte/s, Read speed is Just under 115MByte/s Took almost 5 Hours to verify true capacity with H2testw. Memory test Utility. Moderate Burst write Speed ( 60MBs ) but tapers to 16MBs very quickly.. If you need bulk storage and have all night to write it then this is the drive for you. My Mushkin MKNUFDVS256GB Usb Drive Writing speed: 239 MByte/s Reading speed: 268 MByte/s

I Purchased the SanDisk SDDR-B531-GN6NN Micro SD USB 3.0 Card Reader It's actually a tiny bit slower than a 4 year old SSK SCRM 330 Universal Card Reader.
