The Q540 was spec'd at, I believe, 35ms...but the ST251-1 (not 251) was 28ms.
I do agree about the heat and spindle bearing issues, though, 100%. I have
*never* seen a '540 fail. And they made much cooler sounds. :-)
Hmm. I think I'll ask them about the prices. By the "yet", are you
suggesting that someone is working on it? :-)

The RD31 was
a Seagate ST225, and the RD32 was an ST251...The ST251 did
something like 40ms avg. access, and the ST251-1 was 28ms...The best upgrade I
ever did in one of my pdp11/73s running RSTS/E was replace the ST251 with an
ST251-1. :-)
Quantum D540 is the RD52, 31mb and faster than either of the seagates.
Also the 251 has a lousy track record for reliability (heat and skimpy spindle
bearings). Also, on the
subject of RT11...Does anyone know if Mentec has any sort of
"hobbyist" class license for the PDP11 OSs, or if not, does anyone know what
their actual prices are like?
No on the hobby license yet. No idea on prices.
