Well, even if it uses the BIOS raid, the CPU still has to do all the work.
You can easily spot true hardware raid because of the largish PCI boards,
and the big onboard processors. But this is a budget project... so no true
hardware raid.
I have come to a conclusion now though... as this machine will be used
without a monitor, any RAID arrays will be controlled via a web application.
To do this I need software RAID. Also, from the start it will be running the
following config:
Celeron-II CPU on an i815 board, 256MB RAM
P/M: Boot drive, temporary backup storage for CD-R backup (a few gigs)
P/S: RAID-1 disk #1
S/M: CD-RW drive
S/S: RAID-1 disk #2
In the future, if more storage is needed, there will propably be a three to
four-disk RAID-5 array with some/all disks on a promise controller.
Now this has gone off-topic, so please send replies only to me.
PS. the "mdadm" package is very nice. Among other things it solved the
"array is in use" problem.
