UPDATE:
I found an IBM UltraStar 36LP 9.1 GB 7,200 RPM SCSI drive for $28, so I added it to my IBM UltraStar 36LZX 9.1 GB 10,000 RPM SCSI drive (I got that one for around $40). I cloned my IDE onto the 36LP successfully using Norton Ghost, but LILO wouldn't work, and when I tried to use the "rescue" feature with the Mandrake install discs, it kept trying to find /dev/hda (the old IDE drive). I finally got it working by doing a new install on the drive letting it use only disc 1 of the set (I kept getting errors when I tried all three, and it wouldn't let me continue). I just manually added ProFTPD and Screen after the installation was done (these get left out by using only the first disc). My drives are set up as follows:
36LP: /boot, /swap, /
36LZX: /var (kept all the data from previous installations)
I can definitely tell a difference having the boot drive as SCSI as well as the data drive.
A bonus with Mandrake 9.2: It actually detects both sides of my Dazzle 6-in-1 media reader, so I can now view pics on my SD card from my Linux box. I promptly added a "KODAK$" share to my smb.conf file (for sharing it on my LAN). Now my Linux box is even more of a file server.
