I started with just hosting an nfs/smb folder in baremetal ubuntu server with an old dell optiplex 390 (2011) pc, that time i only know that most people use hardware raid controllers, i din't study about the benefits of raid 5/10 and such, so i opted for the easiest raid option to setup. Then i built my new pc 3 years ago, migrated to proxmox and learned about zfs, but i didn't have a spare disk that i can backup my files to at that time and decided i din't care about data loss, only raw speed so i kept using mdadm raid 0 eventhough it isn't officially supported in proxmox. Fast forward to today, my drives are still running fine, smart values shows no sign of errors, though i already bought a 2x 4tb nvme used as external drive rn, while waiting for 4 of the old hdd to die out....is there any way i can squuze up more performance from these drive to let it die even faster?…
