I now have 3 of these and 3 extra SSDs for storage and backup. I plug this cable into the SSD and then into a USB port and keep all my files stored securely offline. Reading and writing is instantaneous - no wait. I don't have to worry that some $12 an hour "cloud" employee exposes my files online or deletes my files and I don't have to pay some megalomaniac a monthly fee to store or access my files. Even if the Internet is down, my files are available to me on SSD RIGHT NOW.
