Quote: The Mushkin Callisto 60GB SSD proved to be a great drive and it is t he first Sandforce SF-1200 drive with mass production firmware with 13% o ver-provisioning that I have had the pleasure to benchmark and use. I fou nd the performance of the Mushkin Callisto with firmware version 3.0.9 wa s not the same same as OCZs exclusive SF-1200 firmware used on the Ver tex 2 series. This is because the Sandforce Mass Production (MP) firmware limits small file random write performance on all SF-1200 drives except for the Vertex 2 in accordance with SandForces agreement with OCZ. Thi s is why reading reviews is critical before buying an SSD…
