NotebookCheck's results seem anomalous:

14" M1 Pro base 512: 5447.5 read, 4462.5 write
16" M1 Pro 1TB: 5334 read, 5888 write

I assume everyone posting here is using the 5 GB stress file size, but do you want to specify that explicitly to ensure you get consistent results?:

Here are some online results for the 2 TB SSD from iClarified; they seem consistent with what you've already posted. I like these because they ran them five times and took the average:

I’ve got the same model and got similar results… wondering if the 8tb ssd are faster than the 4tb… anyone here with the 8tb?

FWIW - I asked an Apple specialist about this and they told me that you would experience a bottleneck with 64gb unified memory, and 8TB SSD. They told me the optimal config for 64gb unified memory would be 4TB.

16" M1 Max 64GB 8TB ("APPLE SSD AP8192R") with macOS 12.0.1, ~6 TB space available on disk, both tools used with default settings.

Can you explain more about this? Does that also mean you get no speed increase beyond 2 TB if you have only 32 GB RAM?

 

[bluegt]

Looks like performance gains max out at 4TB, but we need more data.

If you are reading this and have a MBP 2021, please share your results.

I'm really not sure of the wider implications, sorry. This is just based on a support chat I had with one of their specialists. They did also say that 1TB of storage would be recommended for the 32 GB unified memory. Hope that's helpful in some way. As someone else said, it will help to see what real users experiences are.

Very curious how an 8TB SSD would cause bottleneck, but does assist in me leaning towards 4TB

Base 16 512gb
I wonder if I should have taken the 1tb version for speed but I only use little storage because I store my photos on my two external nvme ssd (more on in case of failure) and the I still have 370gb of free space on my 16 '
I think I made the right choice, the speed difference is not too high compared to 1TB

Is this 14" or 16"

Anybody has the RAM Disk read-write speed for 16" 1TB?

At the end of the day, 4TB or 8TB... does it really matter? Daily are you able to take advantage of the speed? It's only a couple of seconds, to be honest.

Buy base on storage size needs, anything else is fast anyways.

I mean we are not bringing these computers to the dragstrip, aren't we? 1/4 miles etc. 0-60 no?

 

[hovscorpion12]

There appears to be a lot of focus regarding the SSD now that Apple has claimed 7.3Gbs/s. Which SSD + RAM configuration works best? Which SSD is the fastest? Which SSD results in 0% or minumun SSD cache/SSD swap for the long run.

I've seen posts where it's required that for 64GB of RAM, you must have the 4TB SSD. Anything less causes issues. Any more also causes issues. (ie 8TB causes bottleneck).

I've also seen posts where 64GB RAM + 1TB works well. 32 GB RAM +1TB. 16GB RAM +512GB...etc

Personally, I always say, buy whats in your budget + workflow can handle. If you work primarily off an external SSD, then the SSD size and speed mean nothing.

Do you have any sources on this? How does storage bottleneck the RAM?

 

[Nismo73]

Remember the days of the WD Raptor drive in the 2000s; I think I had the 74gb version. What were those speeds? lol.

Yeah. It's the post above from @something anon

My parents accept MacBook Pro 16" 2021 (maxed out Apple M1 Max with 32GB memory and 1TB SSD) for my graduation in May 2022. I am waiting to get my MacBook Pro 16" 2021 before I can test SSD for speed using Blackmagic Disk Speed Test. I already tested SSD speed on my MacBook Pro 15" 2016 (Intel Core i7/16GB Memory/1TB SSD/Radeon 460) via Blackmagic Disk Speed Test which was my dad's previous MacBook Pro and they earned 1700MB/s write and 1300MB/s read.

My dad's current MacBook Pro is MacBook Pro 15" 2018 (Intel Core i9/32GB Memory/1TB SSD/Radeon 560X). None of my family's computer have 2TB or more storage at this time!

Im about to order 16' and have the same dilemma - 512gb or 1TB?

 

[Spotlighter9]

I think these same considerations from our recent 1TB vs 2TB discussion in another thread would apply to the 512MB vs 1TB as well, hope it helps...

Any Disadvantages to 2TB of Storage vs 1TB on the new MBP?

Hi all. So here's an update. After our great discussion a few weeks back, I decided to upgrade the BTO SSD storage option from 1TB to 2TB, as spending the additional $400 made more sense to me when considering all the advantages of a larger internal SSD. What pushed me over the top was the...
