RAID is imporant for redundance. 99.99% of RAID controllers are in fact slower that straight-up single drive solution but that's the hit you take by ensuring your data is stored more reliably. If you buy a standalone RAID controller make sure you get the one with the most cache since that usually elevates some load from the drives.
Nobody mentioned redundant power supplies. Most colocation facilities have 2 power backbones, A and B. If you get redundant supplies you are pretty much secure as far as power goes, provided your facility has reliable battery and diesel backup.

See? Not just me that says it...
You need to make damn sure those dual lines are from seperate feeds however. I can tell you we moved 400 servers out of verio SD because they told us they did, and they didn't.
Also a good thing to make sure you see their maint schedule for that backup gen. and enough fuel either on hand, or a preagreed contract for the petrol for a few days running at load. Many colo's I know personally don't.
