We all know that SSDs can drastically increase system performance. In fact, here's a great idea: why not set up two SSDs in RAID, and get some great performance? In reality, there SATA 3Gbps bandwidth causes some limitations. Though most platter drives barely saturate SATA II, SSDs are fast enough that they approach, and can often exceed the throughput offered by SATA II's 3Gbps. The next generation SATA 6Gbps should alleviate this bottleneck, though the drive is still being limited to only 6Gbps of bandwidth, which can easily being saturated by SSDs once the storage manufacturers transition to 6Gbps bandwidth this year. This is where moving to a higher bandwidth such as PCI-E comes into play.
OCZ is trying to gain greater ground with their PCI-E based SSDs. In fact, those following the company know that it is shifting focus from system memory to solid state drives starting in 2011. Looking at OCZ's current product line up, we can see how serious OCZ is about this issue. A quick browse through the company's website shows that it has SSDs designed for almost every single segment of the market with controllers based on SandForce and Indilinx.
