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

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.

Performance
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.

Service and support
We always prefer a three-year warranty to ensure the physical integrity of a portable hard drive and we're happy to see that G-Tech backs its G-Drive Mobile USB with a generous three-year warranty. It covers parts and labor with tech support available over the phone, weekdays from 9 a.m. to 5 p.m. PT. The company Web site also offers a list of frequently asked questions, product manuals, and an online community forum to chat with G-Drive Mobile USB users.
