Upgrade HDDs: Cheap consumer SSDs?

[oguruma]

I currently have my Proxmox VE installed on 2x SAS 3.5" HDDs (using ZFS mirror). I have another array of 2x of the same HDDs that I use to store the VM themselves.

Those HDDs are a couple years old now, and I am looking to upgrade.

Is using something like cheap "consumer-grade SSDs" (I will still probably use ZFS mirror) a bad idea? I know that these drives don't necessarily hold up to frequent writes very well.

But, with as cheap as these drives have gotten on a cost per/gb, it seems attractive to use these in lieu of SAS drives.

It all depends. If you want to produce electronic garbage that is probably a fairly good way to do so
I have had old SSDs lying around. MLC ones from the early days, where all vendors placed a lot of apare capacity in them
I thought would be fine but hack, they wear out quick...
I wouldn't purchase new ones... Try getting a decent datacenter ssd from eBay. There is plenty of stuff out there
