1. These take up 1.6 drive bays
2. THey are VERy slow compared to modern drives
3. They are loud
4. They are HOT HOT HOT ...You NEED a fan with these
basically, I would use they in an old server. After using SCSI myself for MANY years, I find that the quick access times of SCSI are so sparingly appreciated unless you have something up to par with a Seagate 15.3, a FUJITSU MAN or MAM, a Maxtor Atlass II or better, or other high speed scsi drives.
For example, my DAD's pc, with a 120GB 7.2k rpm 8MB cache HD lags in only extreme sitations where mine, a Quantum/Maxtor 10kII, never even blinks. My machine is a multitasking marvel. HOWEVER, in standard transfer rates, his DESTROYS my SCSI drives, as does my own WD SE 120GB with 8MD cache.
Use this as a SYSTEM DRIVE ONLY or for server storage if at all, but then again, don't expect miracles unless you are messing with for example, 13GB+ DV files, and are using phtoshop simultaneously as we are.
