If I may ask what were your top three candidates before choosing the intel?

Also why not just plan a graceful switch to a replicated server? At some point you have to detect the drive is about to go (or it just goes without warning). Presumably that point will be in a while and be coordinated with an upgrade like 9.2 in a year.

Finally why not the pci based cards?
