Corsair’s Force GT comes in a bright red chassis, which by Ork logic (in the Warhammer 40K universe) would make it the fastest SSD ever. So is it?
The Force GT consists of a 6Gb/s SATA bus, SF-2281 controller, and 16 64Gb Micron 25nm synchronous NAND modules (as opposed to the eight 128Gb modules on the Patriot Wildfire). This is the same Micron NAND found in the 240GB OWC Mercury Extreme Pro 6G, except that drive had 128Gb modules instead of 64Gb. (Corsair is also shipping the Force 3, which bears the same relationship to the Force GT as OCZ’s Agility 3 bears to the Vertex 3—the Force 3 uses asynchronous NAND and is slightly slower and cheaper than the Force GT.)
The Corsair Force GT uses Ork logic—the red ones go faster.
In CrystalDiskMark and AS SSD’s sustained read tests, the Force GT is as fast as any SSD we’ve ever tested. Its ATTO 64KB read and write scores, single-queue-depth 4KB read and writes, and Iometer random write speeds are likewise nearly identical to OWC and OCZ’s drives. It’s in incompressible write tests, like CrystalDiskMark’s and AS SSD’s, that the Force 3 doesn’t quite match the rest of the field. It’s slower than all the 240GB drives we’ve tested, as well as Patriot’s 120GB Wildfire, by significant margins. In our Premiere Pro encoding tests, though, in which we write a 20GB uncompressed .avi file to the disk, the Force GT was only around 10 seconds slower than the rest of the field—around a 5 percent difference. In other real-world-emulating tests, the Force GT outstripped the Patriot Wildfire but was slower than the OCZ and OWC drives.
The Corsair Force GT has an MSRP of $300, but can be found for the same price as OCZ’s Vertex 3 on the street. It’s very nearly identical in real-world performance—incompressible synthetic benchmarks aside—but OCZ’s drive has a slight edge in real-world testing.
Most benchmarks put it right at the top; pretty red color.
Write speeds (and write-dependent tests) lag behind peers.

Asterisk (*) denotes highest score. Our current test bed is a 3.1GHz Core i3-2100 processor on an Asus P8 P67 Pro (B3 chipset) running Windows 7 Professional 64-bit. All tests used onboard 6Gb/s SATA ports with latest Intel drivers.
