There has been some very interesting statistics that google has
published on their webfarm about SMART. The result were that SMART
catches about 60% of the failures, and that on the other 40%, it doesn't
sees anything. So it's not a very reliable test (I'm not saying it's
useless, just that it wont catch all failures).
As for the badblocks, how did you check for them?
Altogether, I really think that RAID and HDD failure are really a big
issue that us, providers, have to deal with. I wish there was some
reliable solutions out there, considering the imperfection of RAID
(hardware OR software, both have issues...).
