Likely where the 10GbE NIC should be, when you order it.@dosdude1 What is the unpopulated/ empty BGA pad on the other side of the M4 mini logic board for?
It’s more or less underneath the M4 Pro SSD slot, but on the M4 board you dismantled. I don’t know if the Pro board has it.

I understood what you wrote, if what you wrote wasn`t expressing your meaning, the whoops is on you.You misunderstood what I meant.
From what I can tell, I think all the boards are the same, they just either have all 8 NANDs populated or only 4 depending on config. I doubt anything would change in that regard, so it would be safe to assume that 2TB and lower will use 4 NANDs, and 4TB/8TB will use all 8 as usual.
You are most likely correct in that the passive components will also be missing for the second set of 4 NANDs on modules originally configured with only 4 NANDs.
Need to see a pic of both sides of the board with all the tape removed. No such picture has been shown anywhere at this point.View attachment 2452256
What do we make of this? These are photos from someone in China saying he offers upgrade service for up to 4TB, not much more details. The board doesn't look like there are spaces for 8 NANDs? The area with black tape intact also seems untouched. The fact he only does it to 4TB not 8TB seems to suggest Apple actually starts to use 2TB NANDs, so there are no 8 NAND boards?
There are no 2TB NANDs that exist, largest capacity per chip is 1TB.If apple uses 2tb nands they could offer the m4 with 4 tb. But i am afraid puting the 2tb nands in the m4 will not work.
10gb ethernet chip option, I suspect. I saw on other teardown, I forget which.@dosdude1 What is the unpopulated/ empty BGA pad on the other side of the M4 mini logic board for?

Some people are getting well over 4000 MB/s out of their 512 GB drives. I'm getting around 3450 MB/s write, but the drive is half full though.Has anyone done bigger tests on speed for different size ssd configs? On Mac Mini M4Pro.
I saw that the 512gb one is around 3000mb sec vs 1tb 6000mb. Kind of odd if is 2x256gb striped, should be same... Am guessing are slower ssd chips?
They exist, Apple just hasn't used them in their supply chain.There are no 2TB NANDs that exist, largest capacity per chip is 1TB.
Interesting, would make sense that they'd use the new K6B3 2TB NANDs (as you posted previously, I wasn't aware those even existed). No way they could fit 4 more NANDs in there. This also begs the question if the K6B3s would also work on the regular M4 (to achieve 4TB). I highly doubt it knowing how these machines are (only allow officially supported configs), but if I can get my hands on some (and they aren't exorbitantly expensive), I may give that a try.View attachment 2452687View attachment 2452688
Okay this is definitive. At least we know the base model M4 Pro 512GB daughter card has only 4 NAND pads. This means either there is another 8x NAND card, or that Apple has started to use 4x 2TB NAND on this same card, for the 8TB BTO.
