Since you do not say that "hardware raid is required", I assume linux software
raid is acceptable?

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).
