Any code that's reading/writing to SSD needs to use multiple cores. The SSD is faster than a single CPU core.

That doesn’t sound right. A single core should more than fast enough to saturate IOPs (particularly with iouring) unless you’re doing something insane like a lot of small writes. A write of 16mib or 32mob should still be about 1 ssd iop - more CPUs shouldn’t help(and in fact should be slower if you have 2 16mib IOPs vs 1 32mib iop)
Do you want to process that data, or just let it hang out in memory?
SSDs are not faster than a DMA core.
