about why you might not want to use raid5 in this config and maybe
raid1/0
Thank you for the information. I read few articles but I'm not a
company, and
raid1/0 is too expensive for me.
RAID 5 is OK under a few particular circumstances:
- You can tolerate the performance hit.
- You set up a way to be notified promptly if a disk fails, or you
have a hot spare disk.
That last one is critical because if you lose two disks, you're sunk.
Of course, if all else fails you can restore from your backup. You
*are* planning on having a way to back this up, right? :) Even RAID
1 won't help when you accidentally delete the wrong file or the
filesystem gets corrupted. RAID for reliability, backups for data
security...
