The Corsair Force Series GT 120GB is the second SATA 6Gbps SSD that has arrived at G3AR HQ and this one uses the popular SandForce SF-2281 processor. The SF-2281 processor is the fastest on the market, an impressive feat considering that it does not have a cache like its older brethren. Instead the SandForce controller uses its DuraWrite technology to compress the data being written so that less flash cells need to be written to which helps to speed up writing performance.
The Force Series GT is a high-performance version of its Force Series 3 SSD. The main difference between the Force Series GT and the Force Series 3 is that the latter uses asynchronous NAND flash memory and the former synchronous NAND flash memory. The synchronous or asynchronous nature of the flash memory being used denotes when it read and writes to the cell. With Synchronous NAND flash memory data is written both on the rise and the fall of clock cycle which means in theory it can deliver double the performance of asynchronous NAND flash memory. In real world applications the difference is not as massive as you’d think. It is still evident though which is why asynchronous NAND flash is used in mainstream drives like OCZ’s Agility 3 and Corsair’s Force Series 3 SSDs.
The Corsair Force Series GT almost lived up to expectations. In some tests it stood its ground against Kingston’s HyperX SSD but in other tests it fell flat on its face. In sequential read/ write tests the GT is equal to the HyperX but in the burst speed and 4K random read/write tests the GT just can’t keep up. The 4K random read/write test is probably the most crucial when it comes to SSD performance because it simulates the type of small file transfers that an OS does most of the time.
The Corsair Force Series GT goes for anything from R2,500 to R2,800 depending on which retailer you purchase it from and this presents a problem. The Force GT sits in the same price bracket as the Kingston HyperX and on some sites the HyperX is R100 cheaper. When the faster drive is anywhere from R300 more expensive to R100 cheaper it’s almost foolish to purchase the Corsair Force Series GT.
