Does anyone here own a Drobo v2, and if so would you mind telling me
about its noise characteristtics?

Specifically:

1. Ambient noise - this thing does have a big fan after all.
2. If not in use/not being accessed, will it spin down totally.
3. When being read from, is it reasonably quiet (obviously depends a
lot on suitable mechanism but still) or does the fan become some form
of raging tornado.

I found a youtube video which mentions noise, but then he says "if you
hear fan noise it's this Mini Stack not the Drobo'. Hmm - that means I
still can't actually tell what ambient noise a Drobo would make. I
-hate- noise, and as I think I've put in postings a while back a
bearing has gone on a fan in my external terabyte (2x500gig) Ultramax.
You can't replace the fan easily because of how they've constructed it
- there's some metalwork sitting on top of the screws that I'd need to
reach. Been wondering if this is the push I need to finally get my
storage act together and get the Drobo. I do -hate- noise though, so
I'm looking for this to be quiet, ideally silent when not being
accessed.

Cheers,
Ian

I don't have one, but I did happen across one the other day round a
friends. Nice box.

Pretty damn quiet. Nice big fan, slow rotation. Not as quiet as a Mini
though.

If you ask it to - there are tradeoffs, though. The obvious one is
spinup time on access, since they do spin up one at a time = four
disks, 15+ seconds. Surprisingly tedious.

My Infrant NV+ won't run with filesystem journalling if you set
spindown. I'm not certain of the reason for this, or if it applies to
the Drobo.

Yes, assuming you're not using crazy hot drives. The friend above says
it never spins the fan above the base speed. He's only got two disks
in it at the moment though.

The disks (one seagate, one samsung, both 1Tb) are louder than the
fan.

Cheers - Jaimie
