I have 2 of those AB421A HP disks next to me at work. They are indeed brand new, never opened and the 2 I have are dated as February 2008 so they aren't even all that old! The one I opened to look at is a Seagate ST373455LC. Quoted acoustic noise level is 3.6 Bels (36dB?) which is pretty famed good for a 15krpm drive.
At 60 GBP a pop if these are quiet enough I might grab 2 more. They are half the retail price if a new ST373455LC and you could probably resell the carriers on eBay at a tenner a go if you don't need them :P
Link is in my previous e-mail.

I'm a contractor right now and waiting for some work to kick off in September, so trying to make my buffer last as long as possible.
Otherwise I'd have just bought it :)
Also, might be moving to Lebanon so not much point buying crazy servers in the UK...

Fully loaded RX4640 up for GBP 640, that would put a dent in your electricity bill.
Always amazed me that these came with only two drives built in, given the size of the case!
Mark.
Have a look at his Shop - he's got a DS20E on there too :)
Yes, one of those would be nice. Unfortunately, gone are the contractor days when I'd just have bought it.

Yeah HP tend to push storage arrays onto people who use large servers like that.
There's a good case for plumbing the airflow into a room and using it for blown-air heating I thunk!

Now I have a couple of VMS systems running which greatly improves my aging

The contents of the DECW$PRIVATE_SERVER-SETUP.COM file:

Just as an FYI - I redid this tonight on my re-installed 500au and it worked a charm. I set the colour depth to 16 bit and the refresh rate to 60Hz and it works flawlessly. I have a better understanding of the system and how it handles COM files and of EVE as an editor now so maybe that helped. Amazing what some research and a bit of RTFM does for your skills!
Thanks anyhow, I can be a happy DECwindows user on the PSW 500au now :D

I find that drives in specific enclosures for storage arrays, servers, etc. are the best bet and for some reason people don't seem to realise the drive in the enclosure is the same as if bought separate.

Can't really tell but from the lids they look like Seagates.
It depends how new, or modern, the disk is and what quantity. All of my modern 15K (but
also 10K) disks, i.e. all of 73 GB and above, are almost silent compared to older disks.
Maybe I've been lucky, but this has been my experience so far.
These HP original disks in 'ring' sleds (like in the eBay auction) would typically belong
to the above category and are usually of great quality and not high-pitched. Surely not
louder than an rx2600/rx2620, zx6000 even, or let alone rx1600/rx1620 (needless to say,
of course).

Oh yes, and well spotted finding drives in the right sledges! This is no mean trick!
Bear in mind as always that guaranteed new drives are almost always quieter, but that 15k drives are going to be noisy compared with 10k/7.2k/5.4k rpm drives.
Even my laptop drive gets annoying sometimes.
(he says having spent the last 4 hours attempting to get a BA356 loaded with 5 36GB SBBs to talk succesfully to the 1000A also containing 6 drives. In the end the disk in slot 1 of the external enclosure was causing all sorts of horrible problems. Took much swapping of personality modules, cables, host adaptor cards, reflowing solder joints, pulling hair to determine the problem.)
Oh, and time.
