Hi

I have read that DVD RAM is a much more reliable media for important
backups. However I cant seem to see any drives that take the media in
their cartridge, only DVD re-writers like the GSA 4167b that mention
DVD RAM but pressumably use the type 4 cartridge with the disk removed.

Can anyone recommend makes/models that use the disks in their caddies?

You're looking for older SCSI drives. Ebay is your best bet, brands would
be Pioneer or Plasmon (not sure if Plasmon made drives or just relabelled
Pioneer).

The chemistry of DVD-RAM is the same as for DVD-RW, all that is different is
the formatting. There's no real reason to believe that DVD-RAM will be any
more durable than DVD-RW, its main advantage is convenience--DVD-RAM is
designed for data storage and can be treated like just another disk without
kluges such as packet-writing.

Actually there is a serious advantage: RVD-RAM uses verify on write
and does defect management. There is also a second serious advantage:
The cartridge.

If you want durable random-access media in that capacity range you would do
better to go with magneto-optical.

Agreed. DVD-RAM was intended to be the MOD succesor, but it is not
up to it. I have all my important stuff on 3.5" MODs. Usually two
copies. So far I have not los a single bit in 7 years using
this technology.
