Interesting Google hit along those lines:

In my head I cannot always keep clear the distinction between the early 80's IOMega
and the early 80's Syquest removable cartridge drives.
Am I correct in remembering that the Syquests of that time used the 34/20 pin
MFM-hard-drive
"ST506" interface?
Were all the early 80's IOmega's SCSI or did they use something before that?
Syquests were always 5.25" or smaller form factors, is that right? Any 8"
things
I'm remembering are probably Bernoulli Box carts?

I have a couple of old SyQuest drives with this sort
of interface. They're sort of an odd form factor,
IIRC, like a tall 3 1/2" drive. 3 1/2" sized
cartridges though.

I know the first Bernoulli boxes were big 8"
cartridges. I have one such external dual drive unit.
I'm pretty sure the interface is SCSI, but I'm not
positive. I don't have any cartridges, so I never
fooled around with it.
Later Bernoulli drives (early-mid 90's) were 5 1/4"
cartridges. I have seen SyQuest in both 5 1/4" and 3
1/2" cartridge styles.

It has a standard ST506 interface.

Every one I've ever seen has been SCSI (or perhaps a stripped-down
variant of SCSI), but the early ones didn't seem to "advertise" that
fact. The controller board was very dumb.
Syquests were always 5.25" or smaller form
factors, is that right?

I've only ever seen Syquest drives in the 5.25" form factor. The
8" disks you're remembering were probably Bernoulli cartridges.
Those are surprisingly reliable. I used to store quite a bit of
data on a large number of 10MB and 20MB 8" Bernoulli cartridges, then
I wound up using lots and lots of 44MB 5.25" ones (which were
definitely SCSI on Amphenol connectors) at work. This would've been
around 1991-1992. Those were really nice drives.

Unreliable? Hmm.
I have one here that came along with a mac system I was given a while back
(from which I'm happily using the LJ-5 that came along with it that speaks
postscript :-), it's apparently an external unit, 5.25" form factor, and
SCSI interface, and I've tried to do nothing with it so far.
Maybe I won't hurry to use it...

Yes, this is correct. I

Syquest carts were incredibly common in the 80s and early 90s for
storing sounds from samplers. They were fairly quick and tough enough
to survive being gigged.
Pretty much every Emax and Emax II I've ever seen has had a Syquest disk
attached.
