Shortly after publishing a recent 5-way SSD round-up, a number of the manufacturers that employ Sandforce controllers in their products released updated drives that offered more usable capacity to end users. The first wave of SF-1200 based drives to hit the scene had about 22% of their flash memory over-provisioned for cache purposes, wear-leveling, and other proprietary Sandforce functions. 100GB drives like the OCZ Vertex 2 and Corsair Force F100, for example, actually featured 128GB of flash memory on-board.
