Proxmox local and local-lvm speeds

[SGr33n]

Hi!
I'm going to try Proxmox on my Raspberry Pi 5.
Since I have both NVME SSD and SD card, could be in your opinion a good choice to run Proxmox on the SD card and having local-lvm on the SSD?
Or is better to run Proxmox from the SSD? Does it impact on Performances (I don't care of the booting time) having the boot partition on the slower SD card?

Thanks

Hi,

Proxmox cannot run on ARM systems per requirements[0], only non-official build run on ARM, so you should ask the non-official author, since Proxmox has never been designed for this.

Thanks @JeanL I know this, that it's a non official project, but my question could also apply to an x86 system.

depending on your workload proxmox ve will write about 10GB of logs, metrics and other data per day - so no, sd cards are a bad idea, they will die fast.

you could put only the boot partition on sd card and the rest of pve and vm's / containers on the ssd but i think that's a waste of time - just put everything on the ssd, that makes updates and upgrades way easier (except if this unofficial pve spin requires something like this)

sd cards are way slower than a cheap ssd (don't use ssd's with QLC memory - really bad performance), especially iops which are the most important metric for virtualization or containers and with a nvme ssd adapter you should even get *some* performance on a RPI5, depending on the exact model / brand you buy.

if this unofficial proxmox ve spin for arm64 will work is something i can't answer ...

Thanks @MarkusKo I thougt about this choice and I definetely decided to install local and local-lvm on the SSD, leaving the SD for iso and other things that don't require to write file so often.
