Muskin's decision to use the SandForce SF-1200 controller in its new SSD line has really turned out to be a good call. With this controller, you will not only get a drive that is capable of 285MB/sec read and 275MB/sec write speeds, but one that gives some of the best small write performance available for a consumer-based SSD. This allowed the Callisto drive to stay on par with, or ahead of, the INDILINX Barefoot controller throughout the read performance test, but it also allowed the Callisto to absolutely dominate the other drives when it came to write performance.
