I run a SCSI2SD on my A2500 with whatever SCSI card it has by default. The only
issue that I have is the SCSI2SD boots slower than the Amiga, so when I power
on the Amiga I have to wait a few seconds then do the A+A+Control reboot three
finger salute (or whatever it is.) Before it's ready the Amiga just sits at a
white screen forever, but after a reboot the SCSI2SD is ready and it boots fine.
What version of the SCSD2SD V5 do you have? The V5.1 was reworked to boot faster (so
claims the site here
<http://www.codesrc.com/mediawiki/index.php/SCSI2SD#Which_version_should_you_buy_.3F>
) and the V6 boots even faster I believe.
I was wondering about this myself.
It would be nice if the SCSI2SD was mounted on a expansion cover plate though,
with the LEDs visible and the SD card accessible externally.
That's how I them mounted in my MicroVAX 3100 and AlphaServer DS10. On the Alphaserver I bought
the 3.5" bracket and replaced the floppy disk with it. On the MicroVAX I used the same
3.5" bracket and mounted it in a 5.25" to 3.5" bracket with a homemade baseplate.

Is Inertial Computing a good place to buy from? I was looking at their
website. It looks like the latest v6 might be the way to go for Amiga, VAX,
and Alpha. With v5.1 making more sense for my PDP-11/73, due to cost, it’s not
like I’m going to get 10MB/sec on a Q-Bus backplane. :-)

They are. I bought from them just a month and a half ago - the replacement for the
"Drilled" board plus another for my PDP-11/xx (53/73/83 depending on which CPU
board I feel like using) and it was delivered in 3 days despite shipping from CA to TX in
these COVID limited days.
I haven't tested but you're probably right in that a V5.1 is probably good for
a PDP QBUS SCSI card.
