which flash memory kinda sucks at.
Au contraire, flash is amazing at random R/W compared to all previous non-volatile technologies. The fastest hard drives can do what, 4MB/s with 4k sectors, assuming a quarter rotation per random seek? And that’s still fantastic compared to optical media, which in turn is way better than tape.
Obviously, volatile memory like SDRAM puts it to shame, but I’m a pretty big fan of being able to reboot.

Fair point. My thrust was more that the reason why things like system boot times and software launch speeds don’t seem to benefit as much as they seem like they should when moving from, say, a good SATA SSD (peak R/W speed: 600 MB/sec) to a fast m.2 that might have listed speeds 20+ times faster, is that QD1 performance of that m.2 drive might only be 3 or 4 times better than the SATA drive. Both are a big step up from spinning media, but the gap between the two in random read speed isn’t big enough to make a huge subjective difference in many desktop use cases.
