If you head down that road you're about correct. Alot of docs out there
support your claim, but I think that might ONLY be the memory bandwidth.
If you're just using IDE, now way in hell, if you're using UW160 SCSI,
with many drives on caching controller, you could very possibly hit that.
Fibre channel would be about the only way to hit that limit with the least
drives.
