I am on the verge of purchasing a new PM, I'm considering the DP 2.0 or DP 2.3.

The 2.3 I am mainly interested in because of the PCI-X. I have a Adaptec 29160 (PCI/PCI-X) card, and was wondering if this is usuable in the PM. I saw a post of someone selling the same card in the forums so it seems that it will work in the PM? Adaptec's site for the 29160 does not show Mac OS X in the list of supported operating systems.

Also, is there a noticeable improvement in using PCI-X over PCI in a desktop system? I have several Seagate Cheetah 10k rpm U160 drives that I would like to run.

Is anyone using SCSI in their PowerMacs and give me any advice/tips or any links to any further information? I've never tried running SCSI in a Mac system before.

I had an ancient SCSI CD Burner that refused to run in OSX 10.2 and later. No idea about HDs.

Found some articles saying that Adaptec does support the "PowerDomain 29160" (APD-29160) card, and Adaptec has a different product page for it than the "PC" version of the 29160 I have.
(ASC-29160).

They seem to be slightly different cards as the Mac version APD-29160 seems to require a PCI-X as it requires a 64-bit PCI slot and has different dimensions, oh well, I guess I'm getting a DP 2.0

Adaptec's support for OS X is awful. I doubt you're going to get the card to work -- do a search on Adaptec and OS X in Google. You'll find Dantz's article saying Adaptec cards aren't supported for Retrospect.

It hasn't gotten any better. If you MUST use SCSI, you may want to consider an ATTO UL4D card.

If you want to continue using your old gear, just think about whether it makes financial sense. If your hds are small – say 9 gig 10k drives – it would probably be cheaper to buy a Raptor (if you need the speed) which you can simply plug in your PowerMac. Those Mac SCSI cards aren't cheap …

Thanks for the input. I have used the SATA Raptor and still prefer SCSI, but it seems it is too much trouble ($$$) to be worth it.

The Raptor has the same specs (estimated lifespan, warranty) as 10k SCSI drives. If you really need the speed, go for it.
