SanDisk Extreme 240 GB

SandDisk has released four series of SATA SSDs each having a unique feature.
The Extreme series as the name suggests is for those who want exceptional speed. Extreme SSDs are available in four different sizes (60, 120, 240, and 480 GB) and as expected include the latest SATA 3 interface (6 Gbps). SanDisk markets this drive as ideal for computer enthusiasts and gamers.

We tested this drive on both SATA 3 and 6 Gbps interfaces using HD Tune 2.55
benchmark. The drive kept the promise of high speed by giving average transfer
speed of 200 MB/s on SATA 3 Gbps interface and 338 MB/s on SATA 6 Gbps interface which is comparable to Corsair Force GT's speed of 354 MB/s but lower than the Intel SSD 335 Series (375 MB/s, the best SSD we've tested so far). Another important point to keep in mind is that if your motherboard does not support SATA 6 Gbps interface you would not be able to attain maximum  performance.
