I highly recommend raids to anyone who worries about data loss. With HD's being so cheap there really isn't any reason not to. --- end of quote --- So are you running raid to duplicate drives or extend them? I've considered combining two 80 gig drives but I worry about whether it is less secure than seperate. Is combining drives with raid pretty secure after all? Is a raid pair easy to repair? Rich >> --------------------------- My reply: Security for RAID 1 (mirrored drives) in my experience is dependent on how well they are set up. A couple of years ago I a setup a mirrored RAID on identical 9 GB SCSI hard drives in my G3'd 7500 to secure my data in case one of the drives failed. Both drives were on the internal SCSI bus and I used Hard Disk Toolkit 4.0 (OS 8.6) to configure the RAID. After a few months I had severe directory corruption in one drive. Since the drives were mirrored the directory on the second drive was also corrupted. No repair utilities I had could fix the corruption. I ended up initializing both drives. Fortunately I had a third back up and little data was lost. Then a couple of months later the same thing happened again. Perhaps there was a conflict, bug or problem with HDT 4.0 and my configuration -- don't know but that ended my RAID 1 days. Too risky in my experience. Mirrored drives are great if you have a physical hard drive failure. All your data should be accessible on the surviving drive. But with a severe directory failure they do not help (unless you can rebuilt the directory). The same applies with any other file corruption. I find it much more reliable to simply back up to a second drive daily. I takes very little time. And I still use third backup -- just in case. A quick Goggle search revealed this link for RAID definitions; better sites probably exist. Perhaps a RAID 5 or 6 is more reliable but when you have to buy all those extra drives and controllers. . .?
