Subject: Re: [ActiveDir] [OT] RAID 5 Best Practice
One advantage of RAID 5 over RAID 1 mirroring is that with a RAID 5 hot
spare, 2 drives can fail and you don't lose the data which is not possible with
2 RAID 1 mirrored drives.
If the second drive fails before the Raid 5 array has re-built you will
loose data.. A mirror will often re-build much quicker than Raid 5. Raid=5
performance is usually horrid while a re-build is in progress.
However RAID 5 is faster.
Don't you mean raid 1 is faster. And by a long way for write
performance.
Another advantage is that you have to buy double the disks for RAID 1
as compared with RAID 5.
Disks are cheaper than servers. The extra perfromance on a mirror measn
you may be able to get more users on the server.
