What is 'very fast'? In what environment? 

Mylex is best EISA-SCSI controller, what I have tested, but it doesn't
fit to the OS/2-wordl, because of missing HPFS (working ones) drivers.

Adaptec 1740 works allright with OS/2 HPFS, and with SCO Unix, but
the performance is not so good, as with Mylex. I think it is mostly
because of missing HW-cache on-board.
