I have 3 disks that I want to setup in a raid 1, my questions is should I setup the 3rd disk as a spare-disk or should I mirror all 3 disks all the time?
Will it perform *much* better to only mirror two and have the 3rd as a spare. Is it not safer to mirror all 3 drives all the time ?
I have seen some RAID -1 setups, but why 3 drives?
In Raid - 1 Setup, if one drive fails, all others fail. So what is the point in using 3 drives in RAID-1?
I am not an expert on this. But this is quite interesting. Can you clarify this a bit for me please?
with 3 disk you can use a raid 5, 2 disk for data striping with 1 disk for distributed parity.
if you are a raid's beginner you must read and search document with google...
just for say, i post one link to adaptec web site (that document explaine the raid technology)
