SandForce 1222 SSD Testing, Part 3: Detailed Throughput Analysis

Our last two articles have presented an initial performance examination of a consumer SandForce based SSD from a throughput and IOPS perspective. In this article we dive deeper into the throughput performance of the drive, along with a comparison to an Intel X-25E SSD. I think you will be surprised at what is discovered.
