Is it perfect? No.
Is it worth a try? Absolutely!
I have both V5 and V6 and they work very well "most of the time". Some
machines just don't like them (usually in the form of frequent bus resets).
Some machines work better with the V5 and others better with the V6, and
sometimes settings need to be tweaked, but overall I am very happy with
them. I use them mostly as a CD-ROM replacement for installing the OS, and
it saves enormous amounts of time and CD-Rs. Speed is definitely not an
issue.

What is the experience with the SCSI2SD with old

SCSI-1 and SCSI-2 compatible and I see a lot of reports of usage on this
list. I am curious about how well it works and which version to get.
Versions up to 5 seem to be GPLed and reasonably available. V6 does not
seem to have schematics or boards open sourced and I haven't seen a
supplier for them. The web page lists some sources, but they don't have the
V6 available.
It looks like the V6 is not open because someone used the design without
following the GPL.
V6 claims synchronous transfers, but I don't think most of my hardware
supports it. That consists of VAXstations and qbus scsi cards. If I was
after speed I wouldn't be using old hardware, but the speed has to be
consistent with the era.
