Yep, it's all about eliminating bottlenecks and short of testing every permutation, buying the better hardware just makes more sense. By going from HDD to SSD to NVMe, I've ensured that accessing data from my storage device would be as easy as possible. Note that I still have a HDD and an SSD in my PC even though I have two NVMe drives as well. The OS and programs are on a NVMe, most of my flight sims and priority games are on a NVMe, secondary games are on a SSD, and downloads, documents, movies, pictures, etc. are on a couple of HDDs, so each storage solution has it's own place/function

Moved to SSDs about 5-6 years ago and never really looked back
