Number of RAM slots, SSD modules and Thunderbolt data paths

Still waiting for answers to...

2) Is the SSD made from 2 modules such as 2x512GB, 2x1TB and 2x2TB ?

3) How many Thunderbolt data paths are provides with the four Thunderbolt 3 ports ? (much like on the MacPro6,1 which has three data paths each having two ports)

The SSD is comprised of two modules. They are removable, but are paired to the original logic board and data won't be accessible if moved to another iMac Pro logic board. If either SSD card fails or if the logic board needs replacement, the data on the drives will be lost. I suspect this pairing aspect will make third party replacement difficult or even impossible.

The system has two Thunderbolt controllers, each supporting two ports. Each controller is connected via PCIe 3.0 x4. Unlike the MacPro6,1, the PCIe doesn't run through a PCIe sharing switch to split the path.

Some other interesting tidbits are that the Vega GPU is integrated into the logic board and the system power supply is a 500 watt.

While we all want to know the nitty gritty of the system. I would hold off until the great IFIXIT teardown team gives us the unvarnished truth!

Thank you Andrew.

Dan: Yes, when iFixit does a tear-down it will be all very revealing.
