Re: SCSI-1 vs. SCSI-2 -- what's the difference?

[beta@gnh-cathouse.cts.com (Scott Sidley)]

bad info on SCSI-2 removed to irradicate it from the ether.

SCSI-2 is only SCSI-1 with a larger command set. In fact most SCSI-2 drives
will function as SCSI-1 units with the host unable to notice.

however besides the greater number of STANDARD connectors (I do like the
HI-DENSITY 50 pin connectors, but they are a pain to interface to other
non-HI-DENSITY connectors) SCSI-2 also offers FAST SCSI-2 (3 Meg async 10 Meg
sync) , WIDE SCSI-2 (either 16 or 32 bit interface vs the 8 bit of normal),
and of course FAST WIDE SCSI-2 (10 Meg Sync (3M async) and 16 or 32 bit
interface)  These drives are only a few hundred $$$ more than SCSI-1 drive but
offer up to 8 times the performance.

I;m currently using a SCSI-2 drive on my gs with a RamFAST  I percive it to be
slower than my old SCSI-1 drive, however it is faster in all respects, I think
its the fact that I have twice the number of partitions on it.

A point in case: My 500 megs seem to be crowded on some occasions, but I have
found that since I started out with 140K floppies, that 80 megs is in no way
enough.  I have over 400 megs of 3.5's and most of those have compressed
archives.
