Quick Look: G-Drive Slim 500GB

Thin, quiet, reliable and looking good.

The Hitachi G-Drive series of external hard drives is pretty popular; today I’ll be looking at the G-Drive Slim which was designed specially for the MacBook Air.

While I say it was designed for the MBA, there’s nothing in the HDD that will prevent it from working on any other PC. Understandably the G-Drive Slim was pre-formatted for the Mac OSX, but it wasn’t hard to go into Window 7′s Disk Management, delete the partition and reformat in NTFS, where I ran all the benchmarks.

The G-Drive Slim has two unique features which make it look designed for the MBA: the slim profile of just 10mm (nearly the same as a MBA) and the silver aluminum enclosure. Even the texture of the aluminum enclosure is similar to the MBA, except it’s in a matt finish rather than the slightly shiny finish of the MacBooks in general.

The main enclosure is surrounded by a black plastic band, with a mini-USB opening on the front (or bottom, if you will) with a small white LED very much like those on MacBooks. Apart from that there’s just one shiny “G” logo on the HDD. One thing I found slightly irritating, and something that can be an issue over time, is the bottom of the G-Drive doesn’t have any rubber pads. This means the bottom of the aluminum enclosure will get dirty and scratched up with regular use.

For now let’s look at the numbers then. I used CrystalDiskMark for benchmarking the sequential read & write speeds of the G-Drive Slim 500GB. I’ll mention here that the tests were carried on the ASUS Sabertooth 990FX motherboard with an AMD 1100T CPU and WD VelociRaptor 300GB HDD. I tested the G-Drive Slim on both the USB 2.0 port and the USB 3.0 port, with some really interesting results. For comparisons I have used a Samsung external SATA USB 2.0 500GB HDD and a TwinMOS A3 8GB USB 3.0 memory stick.

I have to say those are some very impressive timings on the USB 3.0 write speeds, even with the USB 2.0 rating on the G-Drive Slim. Given the price point of AED 350, the slim profile aluminum enclosure and impressive reading (and especially) writing speeds, I have no hesitation recommending the Hitachi G-Drive Slim 500GB. Just be careful to avoid scratches, as you would with your Mac!


From auditing to editing, I now test and analyze the latest gadgets and games instead of the latest financial statements. Both jobs are equally intense and rewarding. When I'm not burning up hardware in the name of science, you'll find me nuking in DOTA 2 or engineering in TF2.
