Sure, I do have a RAID level on it so a failure per-se isn't disaster. And I wouldn't pay a $1000 dollar premium for it. But I wouldn't mind paying $50 more if it translates to less trips to the cluster room and fewer RAID rebuilds. That's why I'm trying to buy something better than a cheap run-of-the mill from newegg. -- Rahul _______________________________________________ Beowulf mailing list, Beowulf@beowulf.org sponsored by Penguin Computing To change your subscription (digest mode or unsubscribe) visit http://www.beowulf.org/mailman/listinfo/beowulf
