raid question,need anwser

[krisoto]

Have a 60 gig hd. Plan on purchasing 3 more. What I want to do is (1)
stripe drive 1 & 2 in to drive 'a' (2) stirpe drive 3 & 4 into dirve 'b'.
At that point I will have 2 120 gig drives. Then I want to mirror dirve 'a'
and 'b'. Is this possible or does the raid software only mirror physical
drives and not logical drives?

Are you planning on using the software built into 2000/XP?

<edit>
check out this link For a description of RAID 0+1 (as it is often called). The main question is then does the version of Windows that you are running support this....

Avoid the software RAID in 2K/XP at all costs, (hell I advise against the software RAID in IDE controllers at all but that's another thread). It'll bone ya for several reasons:

A) Don't think it'll do RAID 0+1, but not 100% sure.
B) Can't easily boot off the mirror if the first drive dies, it's not like hardware where you just reboot off the working drive.
C) You have to convert the disks to 'dynamic disks' which means no other partitioning software can read them, even reinstalling 2K/XP becomes more difficult.

Unless you have 4 IDE ports you'll have a lot of contention for the IDE bus anyway. I've never used OS X, but since it's based on a Mach BSD kernel it may use the ccd software RAID driver (from FreeBSD), if so you're config will probably work but since it's IDE it'll probably be far from as fast as it could be.
