    This drive is marginally faster than a USB 2.0 drive (I've tested with large and small files), but most importantly it's a solid drive with good value. I've always had good luck with Sandisk drives.

    I have several of the San Disc flash drives and use them often for second copies of files, so I am familiar with the company. The sale price added to the value of this 256GB drive.

    Not much to say about a flash drive . Transfer speeds are more than adequate provided the usb 3.0 ports in PC work correctly . I would buy again , great price .
