ProxMox eating SSDs?

While researching ProxMox I ran into this thread on Reddit
https://www.reddit.com/r/Proxmox/comments/rxl974/does_proxmox_still_eat_ssds/

Does Proxmox still eat SSD’s?

I found out the hard way about 4-5yrs ago that Proxmox used to eat SSD’s when I set up my first host with a 2TB Crucial MX500 as the only drive in my server and started getting SMART errors in the first month.

I know best practice is to use enterprise grade hardware but the price is a bit too steep for me to justify use at home so it’s all old PC parts for me.

Anyone run into this issue on enterprise hardware?
The thread has contributors that indicate this is still a problem today - but most of them are talking about consumer grade cruical devices.

As a side note - this was an issue when using USB sticks to boot XenServer if you didn't disable or moving logging.

I realize SSDs should be a lot more resilient than USB sticks, but still suffer similar write related wear.

There is no "issue". Even those that claim that they are running into it, it's consumer drives with HA logging going to those drives. Its' nothing to do with ProxMox, it's just standard, everyday CoroSync logging. The people saying "this is system administration basics" are correct.

I eat 14 enterprise SSD’s every morning for breakfast. Very tasty and full of protein. The consumer ones are terrible tho and taste like cardboard. Always get the enterprise ones.

Or just understanding what hardware you need for the job.

All VM guest OS will write to the same drive as well. So 10 guests will generate 10 times as many writes + whatever the hypervisor itself is generating.

I just checked and Crucial MX500 have 0.2 DWPD, which is not bad for a consumer drive.
But compare that to enterprise drives that usually start at:

1 DWPD (read-intensive)
3 DWPD (mixed use)
10 to 100 DWPD (write intensive)
