G-Tech G-Drive Mobile USB (500GB) review: G-Tech G-Drive Mobile USB (500GB)

Once a connection between your computer and the G-Drive Mobile is made, you can drag and drop files directly from the Finder onto the drive. The process should be straightforward for techies, but beginners might find themselves wishing for the Lacie Starck Mobile Drive's setup assistant that offers instructions on how to reformat, back up files, and partition the hard drive. The LaCie drive also comes loaded with a copy of the Genie Backup Assistant tool that uses folder-based backups and incremental restoration points to keep your data safe. The G-Drive Mobile USB only offers the drive itself with no extra functionality built in--but keep in mind that the LaCie is more expensive per gigabyte.

Cost per gigabyte
The 500GB G-Drive Mobile USB costs $140, which factors out to 28 cents per gigabyte, coming in 1 cent shy of the Fujitsu HandyDrive. The price disparity isn't as significant as the LaCie Starck Mobile that only nets you 320GB for $100.

As always, we performed a simple data transfer test and compared the G-Drive Mobile USB with four other external drives in a similar price range. According to our tests, the G-Tech beat all four drives by an impressive margin, beating the first runner up at 30.72MBps to read our 6.63GB test data folder. Still, a simple numbers comparison shows that the differences between the top three are so minor that you won't likely notice the difference unless you're transferring a 10GB or larger file.
