[comp.sys.apple] native vs. generic hard disk drivers

TMPLee@DOCKMASTER.DCA.MIL (03/21/89)

I was browsing through a local magazine store and picked up a copy of
Call-A.P.P.L.E.  (first time I'd seen it; now I have to decide whether
to subscribe to it or to A2-Central.)  Anyway, it has the second part of
an article on hard drives that among other things says essentially that
if you are running under GS/OS you get better performance with drives
that have "native" device drivers rather than ones that use the generic
SCSI driver that comes with GS/OS.

Could anyone explain what that is all about and whether it is worth
beating on Everex to come up with a GS/OS driver?  (or, conversely, how
big a job it would be to write one.)  The article implies it has
something to do with running in fast RAM rather than 1 usec peripheral
RAM, but I wonder if that's all.  (and if that is the case, how would
something like a Transwarp GS affect the equation?)
