I don´t know anything about Pc building, and want to buy one. This is a question that came to my mind when doing my research. I think ultimately this comes down to how storage media/storagedevice(s) searches for information on itself. If it´s more of a archiv where everything is labeled and easy to find, or if there are many (example: a hundret) drawers and they are opened till the information is found.
Example:
* 1TB Western Digital WD Blue SN580 M.2 PCIe 4.0 x4 NVME (L 4150MB/s ; S 4150MB/s) ( 34849 )
* 2TB WD Blue SN580 M.2 PCIe 4.0 x4 NVME (L 4150MB/s ; S 4150MB/s) ( 34850 )

It depends…
In theory 2 SSD disks of the same brand and model # but different sizes will have the same read and write performance.
However there are so many on the market that it’s very easy to end up looking at 2 disks of different sizes that are actually totally different spec or brands. Therefore with totally different read and write speeds.
What you have to do is lookup the manufacturers specifications for that specific model # on their website and compare the two.
There are also other bottlenecks to consider. Depending on factors like your motherboard, internet speed (if you are downloading something to the disk), and CPU you may not be able to get anywhere close to the theoretical throughput of the disk you buy making this exercise irrelevant.
But in short… Yes
In your example with 2x SN580s the speeds of the two drives should be the same regardless of the fact that they have different capacities.
Also nickle-and-diming performance to this degree for a home PC probably isn’t worth your effort. So long as you are using a good quality NVME SSD you’ll be getting more than enough performance and a few extra MB/s either way won’t be noticeable.
So spending 8 hours looking at specs to ensure you have absolutely the fastest drive on the market is a waste of time.
