What are the transfer rates for various hard disk formats on a 80286 or 80386 pc clone? Specifically, how fast can an MFM format hard disk using a 1:1 16 bit controller transfer data? And the same for an RLL and ESDI format hard disk, and any other formats if you know of them. Usually such figures are given in bits/s or bytes/s. __________________________________________________________________________ Scott Settlemier Univ. of Oregon scott@cie.uoregon.edu (503)-686-0808 --------------------------------------------------------------------------

Usually such figures are given in bits/s or bytes/s. All these are theoretical maximum values. Anything in excess of these numbers are coming from a cache (either hardware or software) somewhere.
