I missed the explanation for how the SSDs are connected.

Maybe a dumb question.

SSDs are connected via Thunderbolt 5 enclosures. I have one Gen4 and three Gen5 ssds inside enclosures. You can see specs here

So if this all streamed from the internal NVME would you expect better performance?

Just internal 2Tb Macbook M5 Max drive it came in at roughly half the four-drive speed

(0.535 vs 1.038 tok/s at 128 tokens), since one fast drive still has to serve all 16 reads per layer while four drives split the load

Think the M7 will have some storage parallelization?

What exact enclosure are you using?

OWC Express 1M2 (Thunderbolt 5, single M.2 NVMe) — three of them, two on the Mac's own ports and one behind an OWC Thunderbolt 5 hub since the machine has three ports.

Each enclosure tops out at about 7.1 GB/s on whole-file reads regardless of the drive inside (a 2 TB SN8100 measures the same as the 1 TB);

the drive behind the hub reads 5.7 GB/s and falls with queue depth.

Details in the README's hardware section

Thank you!
