Not the GP but I'm in a similar position. I run Hauptwerk[0], a software package that simulates pipe organs. It regenerates an on-disk cache every time an instrument's parameters are changed and this cache can be tens of gigabytes in size. 5 parameter changes a day for some of the larger instruments would put me over your 330 GB/day threshold.

Super interesting, thank you! I imagine there are other music software out there that have similar behavior. What kind of storage do you use to run Hauptwerk and take the beating from all those writes?

I've got a 2 TB Sabrent NVMe drive right now. Apart from budgeting for a replacement drive every few years I don't do anything special.

This is facinating - but would Optane or large RAM-disk work for you?
