Re: RAID and Ultra66

Your comments were quite right, until recently. UDMA33 and 66 approach very 
closely their theoretical rate on the bus.  The overheads are very low, and 
on good drives, the burst is maintained for the entire transfer. IBM has 
included the new Qing protocol in their IDE drives.  Even on a single bus, 
they can get on and off the bus at will.  I think we're going to continue to 
see more action in this area as other vendors follow suit.

I wonder if anyone has written a driver for IDE Qing?
