I have updated the firmware in my MP1,1 to 2,1 in prep to upgrade the procs to 2x X5365.
I had already done the 64b firmware and installed an SSD, Mavs and a upgraded video card.
Is it possible to mount more than 4 drives in the MP1,1?
What is the largest single drive this update will recognize?
According to
#1 , the MacPro1,1 has 6 SATA ports (4 drive bays plus two ODD ports) and 2 PATA ports.
You could probably use the 2 extra SATA ports. You just need to get some SATA data cables and split SATA power from one of the 4 drive bays.
This is a splitter cable allowing the cable to split off power from an existing SATA 22 Pin Power and DATA connection. Perfect for adding an addition SSD drive with limited power sources.

I think the 2 extra SATA ports are under the fan, so you need a 90 degree left or right angle (not sure which - find a photo) 7 pin SATA data cable.
Order 7 Pin ESATA female to SATA female connector, 7 Pin SATA Female to SATA female connector, and blue SATA internal cable at an amazing discounts and free USA shipping

Here's a video:
The video shows one cable is straight and the other is right angle. Maybe you should get the same or get one left angle and one right angle.
I don't think there's a limit to the hard drive size. There exist 14 TB drives.

You just need a place to put the extra drives. Find some adapters, carriers, adhesives, or other methods that can do the job.

There exist PATA to SATA adapters (if you want to install SATA devices in the DVD drive bays), but I don't know how well they work.
