If you don't get an answer here, you might try the Anandtech "Memory and Storage" forum (http://forums.anandtech.com/forumdisplay.php?f=47). Over the past several months, SSDs has been the most frequently discussed topic on that forum. (There have been some threads on SSDs in RAID). _______________________________________________ Mid-Hudson Valley Linux Users Group http://mhvlug.org http://mhvlug.org/cgi-bin/mailman/listinfo/mhvlug Upcoming Meetings (6pm - 8pm) MHVLS Auditorium Dec 2 - MythTV Jan 6 - Git
