Not so in RAID 5. Do you > have any references for your statement above? I hope you're > right and my friend is wrong <gg> NTAP uses RAID4, note RAID5. In any RAID configuration, you have to rebuild the drive that is replaced - even when doing mirroring, where a complete copy of the drive is kept, when you replace the failed drive it needs to be rebuilt. NTAP does hot replacement (hot swap) also, so that statement is bogus. You might want to get the exact quote from your "friend" sounds like something is getting mangled in the translation.
