If possible, it would be interesting to collect a bunch of performance stats for my computer use over the course of a few years to see how often I bottleneck on things like “hard drive read/write speed”. Not sure if it’s worth my time and $100 to replace this SATA with NVME.
I suspect that in almost all cases where I’m reading to or writing from the hard drive, the bottleneck is somewhere else — e.g. network, a drive I’m transferring to/from, speed to parse or serialize whatever data I’m reading/writing.
I imagine my most likely bottlenecks on IO would be during start-up (which is rare and I don’t find it especially slow anyway) or if I’m reading/writing some memory-mapped file (can’t remember the last time I’ve done this), but it’d be nice to get real data on this.
