What to get? If you get an Apple HD, you'll have easier access
to driver updates when or if needed.

Any currently available 3.5 inch 5400 rpm SCSI drive should work. Paying
extra for a 7200 rpm drive is probably a waste, since I don't think the
650's SCSI bus is fast enough to take advantage of it. Stick with regular
SCSI drives that use the standard 50-pin ribbon cable you already have
inside your 650. Unless you already have suitable drive formatting
software, get a drive that comes with its own. Deciding how many MB of
drive capacity to get depends on the size of the stuff you want to put on
it. An inexpensive 2GB drive like the Quantum Stratus is a reasonable
choice for many people and can be had for under $250. There are a number
of mail-order vendors listed in the back of Mac magazines like MacAddict
and Macworld. If you're after the lowest price, you can check out vendors
like ClubMac. If you're willing to pay a bit more for top notch telephone
support/hand holding, you might try APS Technologies.
The new drive will need to be terminated and have its SCSI ID (address)
set to zero. The vendor should be able to provide it in this
configuration.
I have a Centris 650, and I can describe the procedure for replacing it's
hard drive since I just did it this morning. I expect the procedure is
identical for the Quadra 650.
Turn off the computer. Take the lid off. (Loosen the recessed retaining
screw in the back, slide the cover forward, and then lift it up.)
Discharge any static electricity in your body before handling the new
drive or any internal components that could be damaged by it. You can do
this by wearing a wrist grounding strap or by touching the computer's
power supply housing while the computer (turned off) is plugged into a
grounded electrical outlet. (If you use the latter method, it is probably
a good idea to unplug the computer after discharging your static
electricity so there's no chance of the power accidentally coming on while
you're mucking around inside.) Remove the power cable and SCSI ribbon
cable from their respective sockets in the old hard drive. The power
cable's plug may be especially difficult to pull out. Take your time and
be patient. Remove the screw at the rear of the hard drive bracket that
holds the bracket to the metal drive platform. Remove the bracket with
the hard drive. Remove the old hard drive from the bracket by removing
the 4 screws from the underside of the bracket. Attach the new drive to
the bracket using the same screws. Remount the bracket to the metal drive
platform. Attach the power cable and SCSI ribbon cable to the new drive.
Replace the computer's cover. Done.
If the drive has already been formatted by the vendor, you're ready to
run. If not, use the formatting software supplied with the drive or
suitable third party formatting software to prepare the drive for use.

Thanks to all, and another question: what would one do with the old HD --
is it still possible to use it somehow as backup? As far as I know Quadra
650 can only accommodate one intrnal unti.

You can buy/beg/scrounge an external drive case (for around $50) to put
the spare drive in. As a backup, an external drive may be safer than an
extra internal drive. You don't have to keep the external drive plugged
in all the time, so it may be less succeptible to random power surges or
lightning strikes. You can store the external drive in another location
between backups. Also, the external drive has its own power supply, so if
the 650's power supply goes bad and destroys the internal HD (an
admittedly rare event), your external HD will be unaffected.
There are also a couple of possibilities for internal installation of your
spare HD:
1) If your 650 has no internal CD-ROM drive, you can mount the extra HD in
the CD-ROM bay (you'll have to rig up some kind of mounting hardware) and
hook it to the power plug and SCSI ribbon cable plug that were intended
for the CD-ROM drive.
2) If your nubus slots are not all full, you may be able to find room to
hang the extra drive on the left side of the metal chassis that holds the
drives and power supply. It should be OK to mount the drive on its side.
You'll have to rig up some kind of mounting hardware yourself. Then you'll
need to find a suitable 3 plug SCSI ribbon cable and 3 plug power cable
(or branched extender cable). I haven't heard of anybody mounting 2 HDs
and a CD-ROM at the same time in a 650, but I expect it's possible. The
main issue is whether the 650's power supply has sufficient wattage to
handle both HDs, the CD-ROM drive, and whatever expansion cards you have.
I don't know how to predict this. Chances for success are better if both
HDs are low power consumption models.
If you mount two SCSI hard drives internally, remember that the drive at
the end (beginning) of the chain should be terminated and the other should
not. The startup volume should have a SCSI ID of zero, and the other must
have an ID other than zero or seven.
