    Decent speed. Gets warm if you touch the metal portion after keeping it in your computer too long. Not too sure if it will affect the longevity of the drive.

    Good Price and nice capacity of 128 GB. Use it to back up files when I travel and then come back home where I can update my master memory. Plastic body is some what cheap (i.e. thin) and doesn't come with lanyard.

    What a GREAT “pocket sized” storage device, from a brand you can TRUST! I was needing a storage device to remove data from a laptop before “wiping it clean”…and this was EXACTLY what I needed. I have used several of these devices over my 20+ years with the Military and NEVER had any “issue” with it meeting my/our expectations. This is device and company you can rely on when you need a SOLID, RELIABLE product to secure your data on.
