G-Technology G-Drive Slim review review: A hard drive with MacBook Air written all over it

The G-Drive Slim is designed for Mac and is preformatted in the HFS+ file system. Once plugged into a Mac running OS 10.4 or later, the drive works immediately, and it supports Time Machine. In my trials, it worked with Windows computers, too, though as I mentioned, I needed to reformat it into NTFS, which took a few seconds. Otherwise, plugging it in is the only thing you need to do in terms of setting it up.

The new drive doesn't come with any software. This is mostly because you can just use it with Time Machine for backup purposes. Windows users will have to get third-party software for that.

Performance
The G-Drive Slim performed very well as a USB 3.0 portable drive. It's not the fastest I've seen, but it was faster than drives of a similar physical size in many of the tests.

I tested the drive with both USB 3.0 and USB 2.0. When used with USB 3.0, the drive offered 87MBps and 100MBps for writing and reading, respectively. For these two tests, the My Passport Edge registered 83MBps and 98MBps, and the GoFlex Slim averaged 82MBps and 102MBps. Overall, the G-Drive Slim outdid its rivals in most of the tests, by small margins.

When used with USB 2.0, the drive scored 26MBps for writing and 33MBps for reading, slightly below the average. The G-Drive Slim worked very quietly in my testing and produced no vibration and almost no heat at all.
