The Corsair 180GB Solid State Drive is powered by a SandForce SF-2200 SSD processor and fast Toggle NAND memory for both fast sequential read/write speeds and strong random write speed for impressive real-world performance. Benchmarks are great, but your PC doesn't run on benchmarks. Force Series GS has the scores and the real-world performance to back it up. Some SSDs are strong performers with sequential read and write speeds but bog down with random writes. Corsair Force Solid State Drive is better. It's great at both. Corsair Force Solid State Drive supports SATA 3 6Gbps, so you'll get superior performance from newer laptop and desktop PCs that use the newest standard. It's also fully backward compatible with SATA 2. Because SSDs have no moving parts, they can handle shock, vibration and temperature changes far in excess of traditional hard drives. That's important for desktop PCs and essential for laptops.
