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 )

If their specs are the same, then they should be largely the same.
There are nuances around being able to achieve the same performance for the spec sheet, but that’s for the manufacturer to figure out.

Basically any modern file system will be like the first one. The challenge usually isn’t finding the file, it’s actually getting to it. With a hard drive, you have to wait for the reading arm to get to the right place and for the disk to spin to the right orientation. It figures out where to go very quickly. But it’s slow actually getting there.
SSDs don’t have moving parts, so they don’t have this issue. It’s as if you could teleport to the exact drawer you need. Any SSD is crazy fast compared to a hard drive.
But SSDs have other challenges. A single SSD can have multiple storage chips on it, so the workload can be divided. If one chip is busy, you can still do stuff with the other chips. (This is all managed by the SSD itself.) But if an SSD has only a single chip, you can get bottlenecked if it gets really busy.
So for SSDs, it’s the smaller ones that are sometimes slower because you can more easily achieve the capacity with less chips ([Apple did this a couple years ago](https://youtu.be/w6GTf6ATlho?si=ZgM1noefpSe3EADR&t=264))
