Ed, Yes I do have SCSI-I devices on the chain, but I think the performance limits are more due to CPU speed. In tests I can get about 4 megs/second writes and 8 megs/second reads (This test was done on my Application partition which is almost full. And performance is greatly affected by buffer size and configuration. I don't know if MovieShop buffer system is optimized for fast SCSI-II.). But at this speed it is very CPU intensive. The RSCP test showed my CPU working harder than a stock 2000 and a 2091/quantum combo (granted pushing out 10 times more data). But my Warp Engine is the "slow" 040-28 model. When I push the V-LAB hard it is easy to see that the disk writes are eating CPU cycles to the point where you can't even move the mouse pointer in the MovieShop screen. I think an 040-40 would greatly improve the system. …Warp Engine Engaged… -Paul-
