That sounds absolutely fine to me.

Compared to an NVME SSD, which is what I have my OS and software installed on, every spinning disk drive is glacially slow. So it really doesn’t make much of a difference if my archive drive is a little bit slower at random R/W than it otherwise would be.

In fact I wish tape drives weren’t so expensive because I’m pretty sure I’d rather have one of those.

If you need high R/W performance and huge capacity at the same time (like for editing gigantic high resolution videos) you probably want some kind of RAID array.

That was a different technique, using simulated evolution in an FPGA.

An algorithm would create a series of random circuit designs, program the FPGA with them, then evaluate how well each one accomplished a task. It would then take the best design, create a series of random variations on it, and select the best one. Rinse and repeat until the circuit is really good at performing the task.
