This very quick solid state solution doesn't break the bank, it receives 4/5 from TR.

"We've had a play with OCZ's first take on the PCIe-based SSD, the OCZ RevoDrive 120GB and you could colour us fairly impressed. A little while later and the OCZ RevoDrive X2 240GB has found itself slotted into our test bench. OCZ's first SSD-on-a-PCI-card turned out to be a neat way of getting around the bottlenecks that current (SATA 3Gbps) and future-facing (SATA 6Gbps) interfaces are finding a problem for SSDs."
