This DMA transfer is not at full speed since Yeah, I know that. BUT - if writing a 3.5 MB zoo-File takes me with the GVP x seconds and with my 2090A with the ST506 drive ALSO x seconds and with my 2090A with my new Seagate ST157N 3/4x seconds, my choice concerning speed is quite clear. Beside that - directory scan goes about 2 times faster using my 2090A. >The net result is that the processor therefore spends less time on the data >transfer and is available more often for other concurrent tasks.

But you know, for me it is not important which controller work better in theory but which one actually does a better job while using it. I never marked any more slowdown in multitasking when using the 2090A, and I use multitasking a LOT. >all the CS and EE types here on Usenet recommend GVP while the doof dummkopfen >in Deutschland recommend the rest. Well, I agree that there are many 'doofe Dummkvpfe' (stupid fools) in Germany (as everywhere in the world), but not all are like this. Remember, they brought us the A2000.
