In this video I take a look at many different aspects of a boot drive used for Proxmox VE. I do testing to find out how much space, endurance and speed is needed. I also go over many different types of drives that can work as a boot drive and what would work best for a server.
Here is the link to my script that I used to get the daily writes on the drives in Proxmox. https://github.com/ElectronicsWizardry/linuxDailyDriveWrites
