Unlike my 500 GB pocket drives, this TB offering can be powered from a single USB port on my laptop. However, the port used has to offer a 5V trickle of power because the drive needs to spin up for efficient data access. You cannot expect older desktop computers to have USB ports that meet this power requirement. One of the four USB ports on my Dell M2400 laptop does not have the power to run the drive.
My Toshiba USB Drive could transfer my bloated media files at 5 Gbit/s but I'm stuck with a Windows 7 Pro laptop at USB 2.0 so I get one tenth that transfer speed. That's actually not a big deal for me because I would rather do my back-up routines while working on my laptop. I bought the Toshiba Canvio for EUR 119 from D.I.D Electrical in Clonmel. It came with file, folder, and full system backup and recovery software with data encryption. I am mapping its use to Crashplan. This is the first time that I looked for the manufacturer to state that the drive had internal shock sensor technology on board because I've dropped these pocket-sized drives before. I hope to get more than two years' usage from this purchase but I think the connection point for the cable at the back of the portable drive is the weak link in this product because I cannot turn over the drive while it's running and expect it to hold its connection to my laptop. Toshiba Canvio 3.0 Plus Portable Drives are compatible with Windows 7, Windows Vista and Windows XP.
The Toshiba Canvio Portable TB Drive should cost you less than EUR 120. You're probably paying EUR 10 just for the brand name, one I trust with my data.
