[ILUG] Scsi speeds?

[ILUG] Scsi speeds?

I was very impressed by the 78.5Megs/S parameter for disk access thrown out 
recently on the subject of cd burners. I have a system here with 2 ide disks, 
and disk access is crap, to put it mildly. I'ts not a server - just my own 
thing, a k6/3-500, 100 Mhz bus, 66 Mhz agp, 33 Mhz pci & ide, and 2 rather 
doubtful disks, all built around the rather doubtful Via Apollo MPV3 chipset.
hda (Maxtor) achieves 7.splash Megs/s and gets lost in any useful dma modes. 
Hdb achieve 12MB/s. Ringing has been known to occur between disks when 
thrashed.


Question: If I threw in a decent pci scsi card and disk, got past the 'System 
Can't See It' stage, what sort of Meg/S could I reasonably expect? Clearly 
not anywhere near the 78.5Meg/s, but would it be worth the expense?
