m.2 NVMe 256GB vs larger

[PoBoy]

A 256GB SATA SSD generally doesn't perform as well as a larger capacity SATA SSD.

Is the same true for m.2 NVMe SSDs ?

Cache and DRAM makes the difference

you just made a very vague statement. The difference between sata and nvme depends on lot of factors. to begin with the protocol (nvme vs sata/scsi)
are you planning on buying nvme drive?

For a relative. Wanted to get a 256gb one, for the lower price. Then realised that, maybe, larger capacity would perform better.

I knew 256gb 2.5" SATA SSDs are much slower than the larger ones.

From what I have heard, once the SSD fills up over 50%, it starts to get a bit sluggish. Something to do with available free space for swapping data or some such. My own SSD's are barely over 50% filled so I have never experienced it. But i have heard a lot of tech reviewers suggesting to keep a large portion of the SSD free.

I might be wrong though..
