As the landscape of SSD drives continues to evolve, it becomes more difficult for consumers to discern the good drives from the not so good and which ones offer a good value. To make it tougher, many manufacturers have several different lines of drives that offer various levels of performance. Corsair is one such manufacturer and they've sent us over three drives to test out around the same time so we thought it'd be good to do a roundup to give some head to head comparisons. We have a pair of SandForce based Force GT drives - one at 180GB and a larger one at 240GB. Also in the mix is a single Performance Pro 256GB drive which has the latest Marvell controller. All three have a SATA III interface and a three-year warranty.
