Ask HN: Why don't operating systems provide complete SSD write accountability?

1 points by amichail ↗ HN
Excessive writes can wear out an SSD. So even one bug could kill your computer. (Not all SSDs are replaceable.)

So why don't operating systems always tell you precisely what app/service is responsible for excessive writes so that you can turn off the app/service and contact its authors?

Wearing out an SSD generally affects performance well before there’s any kind of failure.

What operating system are you using that doesn’t expose metrics on per-process disk IO?

macOS processes launchd and kernel_task write a lot but don't tell you the root cause for those writes. So you don't know what services/apps to stop using.

Are you actually seeing things bunch up there? If I open activity monitor I see the writes attributed to individual processes the way I’d expect.
