We have scsi now, and I just guessed that we might use it again. I'm
prejudiced toward scsi. I'd rather have slow processors and scsi than
anything else and IDE/EIDE/ATA/SATA or whatever flavor MFM comes in
today.

Since I didn't know what NCQ was, I looked it up. The article that I
read seemed to indicate that the SATA controllers on motherboards
don't support NCQ yet. Can anyone name a board that does support it?
We don't really have a space problem.
/dev/sda3 7.5G 3.3G 4.3G 43% /
tmpfs 245M 4.0K 245M 1% /dev/shm
/dev/sda1 89M 5.3M 79M 7% /boot
/dev/sda7 16G 1.6G 14G 10% /home
/dev/sda6 957M 33M 925M 4% /tmp
/dev/sda5 9.4G 6.2G 3.2G 67% /var
All this on a 36Gb drive. If we had installed with LVM, we could
rearange the space a little if we needed to optimize the drive space.
But, it's not been a problem so far.
