RAID 0 is striping and is used *only* for performance reasons. If you don't think you'll need the additional performance, don't use it. You will lose redundancy in favor of the performance. If either drive fails, you lose your data. RAID 1 is mirroring. When you do your initial Red Hat Linux 7.2 install, you can configure this, and it's easy - it's well documented in the Installation Guide and takes an extra 5 or 10 minutes to set up, and then it just runs without you having to do anything else. It's what I run at home. RAID 5 is striping + mirroring. I recommend that this not be done on IDE drives unless you've invested in extra controllers. You need at least 3 drives to make a RAID 5 set. RAID 0+1 will give you the highest performance at the expense of the most drives. For a home system, RAID 1 is no longer out of the reach of the average PC purchaser. I added 2 40GB ATA100 drives on the Promise TX2 controller for about $240. I mirror the first 10GB of data so that leaves me 70GB of usuable space. That's a lot of disk space for not a lot of money. A few years ago, this would have been prohibitively expensive. Naturally, I still do backups of my data (to hard drives, not tape). -- Ed Wilts, Mounds View, MN, USA mailto:[EMAIL PROTECTED] _______________________________________________ Redhat-list mailing list [EMAIL PROTECTED] https://listman.redhat.com/mailman/listinfo/redhat-list
