EVERYTHING that Unix does requires an access to the disk. Very true. Question: Does the C= (or any other) Amiga SCSI controller suport "synchronous" SCSI? I seem to recall the difference in maximum throughput being more than a factor of 3. (BTW, the Quantum 110MB drives support this.) If we can believe Dave Haynie (personally, I believe *everything* that Mr. Haynie says :-), the disk performance of the 3000, at least, is limited by the disk. Furthermore, DEC's PMaxen (just as one example) get perfectly acceptable disk performance out of an asynchronous SCSI disk while running Unix. Therefore, an A3000 should do just fine disk-performance-wise running Unix. andrew -- Andrew Heybey, ath@ptt.lcs.mit.edu, uunet!ptt.lcs.mit.edu!ath
