We have been using dual Kingston 120GB SSDs attached to on-mobo sata ports and linux mdadm raid1 for a few years now without any special problems. Some web sites suggest special settings for SSDs in RAID1 configurations, suggest the importance of TRIM, etc, but (as a test) I ignore all that and use them as if they were normal HDDs. See no ill effects. One thing to remember with SSDs - unlike HDDs that seem to soldier on forever (just retired some still working perfectly HDDs from 2004), the SSDs do have finite write capacity and they *will* die eventually (see the eye-opener test of SSD capacity that just completed in February or so). -- Konstantin Olchanski Data Acquisition Systems: The Bytes Must Flow!
