That's a nice bonus for anyone who frequently hops between systems. It also includes drivers to run on a Mac, though, allowing you to use it on either operating system without reformatting. It's formatted NTFS out of the box, so it will work right away on any Windows PC. The only connectivity option is a single USB 3.0 port, for which an 18-inch cable is included. As with the Backup Plus, there are no rubber feet on the bottom, which makes it prone to slipping around or off most surfaces. The Seagate Backup Plus Portable Drive, for instance, is much more substantial at 0.8 by 3.1 by 4.5 inches and about 8.6 ounces.

The bottom portion is black, and the whole rectangular body is made of plastic.Īt this size, it's larger and heftier all around than something really small (and pricey) like the Samsung Portable SSD T3 ( at Amazon), but it's still slim and nowhere near what I would call heavy. It's stylish, too, with a modish dimpled pattern on the top and a platinum finish (though it's also available in gold). It can fit in your front or back pants pocket for travel, though it would take up most of the room since it's fairly wide.

Design and Features Living up to its name, the Backup Plus Ultra Slim ( at Amazon) is a super-thin drive, measuring 0.37 by 2.99 by 4.46 inches (HWD) and weighing 4.3 ounces.
