Re: off topic - scsi partitions & swap & raid
Concur with Wesley - raid on one drive is like mounting a ramdisk as /tmp
- pointless because any benefits from the technique are nullified by the
way you've done it.
Now for:
raid 0 (striping) min drives 2, reads and writes faster, no reduncancy.
raid 1 min drives 3, 2/3 of your total disk space is available. Fault
tolerant.
raid 4 min drives 3(?) One whole drive is for parity.
raid 5 min drives 3, distributed parity bits, allows one disk to fail.
raid 6 min drives 4, distributed parity bits, allows for two disks to fail.
I'd recommend two more 18 Gb drives for a speedy 54 Gb raid 0, or a 36 Gb
raid 1 or 5.
(from the guy who has been playing with raid on three 80 Mb conner scsi
drives.)
(next plan is to make a raid 0 or 5 over a raid0(80+80+80) + raid0(80+160)
+ 250 Mb
drives. Need more power supplies first :)

I really need to do two 6 gig, 2 128 meg, then what's left for windows?
This will be my first time for raid & scsi under linux, is there a nice howto
that covers both?
