"As it turns out, Microsoft slipped the update into the final patch Tuesday of 2021 for both Windows 10 and Windows 11."
Most of the time the HD grind is caused by Chrome scanning my files, but still, I wonder if all the verbose logging and tracking that Win 10+ does now is what made them recommend upgrading to SSDs for the OS'es.
I'm also pretty sure that Win11 has a lot of structural changes made to eventually inject ads into everything as a back-up MS-Revenue Stream plan, so I'll wait for the usual mandatory to update anyway, after there is no longer a choice.
Maybe it's their devs not having HDDs anymore. Who knows. I'm pretty sure it's not the volume of data being read/written. Just a lot of more smaller reads/writes or less attempts at latency-hiding.
Be it the anti-malware, less carefully written system apps or whatever. I think especially XAML stuff had terrible start-up times on HDDs. I remember filing a feedback item because after booting up my laptop it took more than 40s to open up calculator.
