Currently STEC has the only FC-interface SSD, but SAS drive use is ramping in the high-performance drive space and FC hard drives look set for a steady decline in use, weakening STEC's advantage. Hitachi GST will bring in SAS interface enterprise SSDs in the first half of 2010 and may introduce FC interface products as well. Although STEC has SAS-interface product it doesn't have the market penetration that its FC product has, and so an SAS-interface market-dominating position, like its FC-interface one, is quite unlikely.
