Can't agree with this strongly enough. Grab the best UPS you can afford
(and often that means getting a 10 year old one second hand and
replacing the batteries). Best investment I _ever_ made was a 2000
vintage APC SmartUPS 2200 and it cost all of about $200 second hand,
plus another $100 for new batteries.
Also, look at adding a bitmap to your array. Then it will only resync
what it suspects might be dirty.
