Will try connecting to m2 directly next. Big thanks to egpu.io for being such an awesome resource.
@mbp2014ftw, This is an excellent build! Where did you find the M.2 to Thunderbolt 2 enclosure? I was searching for one but failed to locate anything suitable. You'd get better performance through M.2 eGPU with the RTX 3070. Through NVMe interface, I don't think you need to do anything to boot Windows 10 off the enclosure, such a convenient adapter to switch between external boot drive or external eGPU.
Few years ago I bought https://www.amazon.com/Transcend-JetDrive-825-Thunderbolt-TS480GJDM825/dp/B078YKYGBS/
To be clear, I am still using NGFF adapter with it. A perfect sandwich
I do wonder why am I getting only pci-e x2 in this configuration?
@mbp2014ftw, PCIe 3.0 x4 is a rare configuration on non-Thunderbolt 3 Macs. I've been keeping an eye out for a 2015 27" iMac which has the SSD socket with a good connection. It would make a fun M.2 eGPU build, storing the ADT-Link R43SG and eGPU in the back of the iMac leg.
Also, have you tried to connect it directly to the internal ssd slot?
According to this page: https://www.transcend-info.com/Products/No-850
The Thunderbolt interface of the JetDrive enclosure is only Thunderbolt 1 (10 Gbps), therefore the PCIe connection in the enclosure is only PCIe 2.0.
PCie 2.0 x4 can do 1600 MB/s but Thunderbolt 1 limits that to 10 Gbps (≈835 MB/s).
Check the PCIe and Thunderbolt info to verify.
Connected it internal port:
Got plagued by error 43 but after applying nvidia-error43-fixer two times - it finally worked. Had to use remote desktop since both internal and external screens were black :/
@mbp2014ftw, That looks good and it's closer to Thunderbolt 3 throughput than Thunderbolt 2.
