Mushkin is announcing the EP Series of SSD drives based on the new SandForce SF-2000 processors, with 6GB/s burst speeds. How fast? That’s 768MB/s compared to the current 285MB/s of the Callisto series.

Sequential read and write speeds are 500MB/s, while each can sustain a rate of 60,000 operations per second. That’s a lot of I/O, and it’s coming to gilded racks sometime in the first quarter of 2011.
