My question kind'a stands: If the only thing I ask of it is for the data to be safe (no speed or "no downtime!" issues) is there any reason to use hardware over software raid?I do not care if I have to take the server down for an hour (or 2, or 3) to replace a disk, be it a raid disk or boot disk. I have plenty of time, I could even run down to the store, get a new bootdisk, install debian and be up and running in 2 hours. no problem. ONLY thing that is important is that the data needs to be safe. if 2 of the raid-disks fail I need the data to be safe. (it is, of course, a budget thing. In case of fire I have tapes to get the data back, there's downtime involved there. So I do care about downtime. Just that with disks being as cheap as they are I was thinking that a software raid is soooo cheap to build that maybe that's worth the extra cash for the 3 extra disks that I need to buy. scenario 1: boot of scsi, data is on a 200G IDE, tape backup scenario 2: boot of scsi, data on 4x80G IDE (software-raid5), tape backup = + EURO 100 scenario 3: boot of scsi, data on 4x80G IDE (hardware-raid5), tape backup = + EURO 500 scenario 4: boot of scsi, data on 4x80G SCSI (hardware-raid5), tape backup = + EURO 2200 so for close to nothing (E 100) extra I get software raid. Is hardware raid "safer"? (I do not think it is, I'm just waiting for someone to tell me I'm being naive here) Tinus.
