I can't remember any hard disks greater then 50MB
being available even
into the late 1980's.
CDC 9766's (300mb also sold as DEC RM05s) came out in 1979
Similar size drives were being made by IBM and Burroughs
Sperry, Memorex, etc.

Yes it's an easy softball to hit out of the park but many
of us appreciate the historical data.
We were very familiar with the CDC 300 MB type units round
about 1983, when they were getting a bit old. I assisted in
placing a brand-new DEC ~700MB nonremoveable pack drive at GE
San Diego for some important work there and am trying to retrieve
data on that one. It was a big one, Maybe a foot above the CDC's,
perhaps five feet overall.

ISTR we got our 450 MB RA81 in the middle of 1984. It wasn't really

was contemporaneous, but I can't recall its exact year of release.
By the mid-1980s, 400MB+ was "ordinary" if you had the $10K-$20K to
pony up for it. OTOH, due to cost, lots of sites made do with older,
smaller capacity disks.

I think the RP07 is closer to 1981, at least I see traces of them in
source code dated 1981.
Then again, the RP07 is a rather big cabinet, while the RA81 is a rack
mount unit the same size as an RK05 or RL02.
