While there is often a perceptible difference between a SATA SSD and an NVMe, it's nothing compared to the gap between a spinning disk and any reasonable SSD.

While there is often a perceptible difference between a SATA SSD and an NVMe, it's nothing compared to the gap between a spinning disk and any reasonable SSD. If you're doing anything on the web, a good adblocker makes a big difference. If you have 'enough' RAM, more doesn't help. For most tasks, CPUs are wasted most of the time. 2 3Ghz x86-64 cores are good enough not to be noticed on a general desktop. Latency remains more noticeable than bandwidth at modern levels: the difference between 100Mb/s and 1Gb/s is only noticeable when doing bulk transfers. All that being said... most of what we use our end-user computers for is wasteful overhead. Too many layers.
