So with RAID 1 I'll get write-speeds like I only have one drive with no RAID, but with RAID 0 I'll get write speeds like I have umm... RAID 0... but the read speeds are (effectively) the same, correct? > The performance is usually irrelevant for the decision of RAID1 vs > RAID0. True... makes me wonder about the frequency of drive faliures. Those who have experience: how often does that happen? I've never had a drive fail in my life, but I'm your normal desktop user so my PC is off for about 8-16 hours a day. Dang it, fate would have it that I should leave now, but I shall return (sometime later today, if fate does not conspire against me...) Thanks for all your great help and I hope that I'll someday be able to repay you all in kind... -- === GCB v3.1 === GCS d-(+) s+:- a?
