It's not all that often that entire new product markets open up in the PC sector; when they do, companies have to jump in fast to get on the boat before it pulls out of the harbour. Mushkin, known primarily for its performance RAM, wants to get on the SSD boat in a big way, similar to OCZ, so they are introducing another line of SSD drives.
Named after another moon of Jupiter, the Callisto series is more the mainstream offering than Mushkin's existing performance Io line. Coming in 60, 120, and 240GB configurations, the Callisto solid state drives feature Sandforce controllers, 3 year warranties, and a MTBF of 2 million hours. Read/write speeds are said to be 285-275MB a second.
They will be hitting hardware stores in a matter of weeks (in North America anyways), and will sell for $240, $407, and $733 USD, depending on which drive capacity you choose.
