G-Tech G-DRIVE hard drive - 500 GB review: G-Tech G-DRIVE hard drive - 500 GB

Cost per gigabyte
The 500GB G-Drive Mobile retails for $150, which works out to 30 cents per gigabyte, a full 15 cents cheaper than the Iomega eGo Portable Mac Edition, a similar external drive with 500GB and the same FireWire and USB connections. Although USB-only drives like the Samsung S2 cost a fraction of the price at 19 cents per gigabyte, the performance chart below shows that the speed gains of FireWire 800 over USB 2.0 are worth the extra cost if you frequently transfer large amounts of data.

Performance
As always, we performed a simple data transfer test and compared the G-Drive Mobile with four other external drives in a similar price range. According to the chart below, the G-Tech championed all four competitive drives by an impressive margin in the USB 2.0 throughput test; the Iomega eGo Portable Mac Edition jumps ahead of the G-Drive in a straight FireWire to FireWire speed competition. Still, a simple numbers comparison shows that the differences between the two are so minor that you won't likely notice the difference unless you're constantly transferring files of 10GB or greater

Service and support
We always prefer three years to ensure the physical integrity of a portable device made to withstand the abuse of daily transport, so we're happy to see that G-Tech backs its G-Drives with a generous three-year warranty. It covers parts and labor with tech support available over the phone, Monday through Friday 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 other G-Drive Mobile users.
