M3 Macbook Pro 512GB SSD

[Telekinetic]

Do we have any data yet on whether the M3 Macbook Pro with 512GB has two 256GB NAND chips or just a single 512GB chip?

 

[DribbleCastle]

Also curious to know.

Two chips according to Luke Miani

I saw a live test on YouTube guy benchmarked his 512GB at 4-5000MB/s

This surely is an increase, not really sure if it is really dual NANDs though. Need teardown to confirm.

For context, the 1TB on my M3 Max scores 5-6000.

EDIT: I must clarify, that video I watched was actually testing a base "M3 Pro" 14". Not the "M3". So looks like it is not what the OP was asking for.

A teardown video and the benchmarks confirm it: dual 256GB modules

Ya it’s dual.
Close to 5900MB write and 5100 read on the m3 pro 512

On my m2 pro 512 it was 3300 both ways

Seen videos of it being close to 8000MB on the 8TB models

Just as a note, 'the base version of the new MacBook Pro 14 with the M3 SoC only uses a PCIe 3.0 interface instead of PCIe 4.0 on models with the M3 Pro or M3 Max'.

So on base M3 14 inch speeds are like 2900/3200.

Also base M3 has only one fan = running louder.

Anyone have a m3 pro with a pro chip with the 1tb SSD?

I do. What do you want me to check?

I do. What do you want me to check?

Blackmagic speedtest set to 1gb please

Blackmagic speedtest set to 1gb please

Write 6392 Read 4892. How do you get the test to automatically stop without starting another test?

How do you get the test to automatically stop without starting another test?

I don't think u can. But thanks for doing that. Could you set it to 5gb and see what the results are.

Thanks
