I have a couple of ST33000651AS in my server, they failed several times, but the current pair has been running for more than 1 year, I guess they just got a nasty batch.

Needless to say, rebuilding 3 TB raid took a long time and downtime and pain... but all in all, it was worth it, considering the prices.

I can also confirm support was quite fast, even if some of the replacement drives were not new and some even came with bad sectors lol ... such is life.
