The Good The good-looking G-Tech G-RAID with Thunderbolt is very fast for a dual-bay external drive of its type. The drive supports RAID 0 and RAID.

The Bad The G-RAID with Thunderbolt is comparatively expensive among similarly configured devices. Its hard drives are not user-serviceable, and like all Thunderbolt drives, it doesn't come with a Thunderbolt cable or support any other connection types.

The Bottom Line All things considered, the G-Tech G-RAID with Thunderbolt makes a decent investment for Mac owners who have the funds for a fast storage solution.

The G-Tech G-RAID with Thunderbolt is the third dual-bay Thunderbolt drive I've reviewed and compared with the other two, the WD My Book Thunderbolt Duo and the LaCie 2big, it's the fastest one. Unfortunately, it's also the most expensive, costing some $700 for 4TB (or $850 and $1,000 for the 6TB and 8TB, respectively), and the only one that doesn't allow users to replace its internal hard drive.

Other than that, the latest addition in the Thunderbolt storage ecosystem is overall very similar to the rest: fast, expensive, supports only Thunderbolt connections, and doesn't include a much-needed Thunderbolt cable, which costs another $50.

That said, if you're in the market for a Thunderbolt-based storage device, the G-RAID with Thunderbolt is another decent investment among the limited amount of Thunderbolt storage options on the market.

The G-Tech G-RAID with Thunderbolt bears the same design as other G-RAID drives; it's shaped like aluminum brick. The drive is shiny and is about as compact as an external drive that houses two 3.5-inch hard drives can be. It's also good-looking; similar to a Mac Pro desktop computer, just much smaller.

On the front, the drive has one large, square white light that shows the power status (solid white) and the activities of the hard drives on the inside (flashing white). On the back it has two Thunderbolt ports, a little ventilation fan, and a power button that you'll need to press and hold for a few seconds to turn the drive on or off.

The G-RAID is the second Thunderbolt drive I've worked with (the other is the Promise Pegasus R6) that comes with a power button. And you'll need this power button since, unlike the rest of the Thunderbolt drives, the G-RAID doesn't share the same power status as the computer to which it's plugged in. This means it will stay on even when the Mac is turned off and won't turn on by itself if the when the connected Mac is powered on.

The two Thunderbolt ports mean that it can be used in a daisy chain setup as any part of the chain. I tried it with a few other drives and it worked very well. Up to four other Thunderbolt devices can be used with the G-RAID to connect to one computer.

The two hard drives of the G-RAID come in a RAID 0 configuration, offering one single HFS+ volume that is the total of the two hard drives' capacities, which was 8TB in the case of my review unit. RAID 0 also allows for very high performance, but if one of the hard drives dies, you'll lose data on both. For data safety, you can use a Mac's Disk Utility to change the hard drives into a RAID 1 configuration, a process that took just a few seconds in my trials. In RAID 1, the drive offers just half of the total storage space.
