Hey folks, I’m at my wits end. I’ve been screwing with proxmox for years now, but I’m at a tipping point. I’ve just used consumer SSDs in it to run my VMs off of - but I just realized after a dozen or so crashes over the last week that I think the SSDs are the culprit. (Really, really terrible write speeds leading to kernel crashes I believe).
I’ve never gotten an enterprise SSD, if that’s even what I need. Any recommendations? New? Used? Brands?
I use mostly Samsung, SK Hynix, Micron and SanDisk. For bulk storage it doesn’t really matter which of those you pick but for fast storage you’ll want to be sure the drive offers PLP.
Go hit up fleaBay and see what’s available in the way of enterprise drives in the size you need then google the model numbers and check out the datasheets. Once you know what each drive is capable of you can decide which to buy. I usually try to buy 3 dwpd models for VM storage and 1.3 dwpd for bulk, you might prefer to focus on IOPS over endurance it’ll depend on your application.
Edit: for a VM host pool you’re primarily going to be concerned with IOPS, endurance and having PLP for better ZFS performance. For bulk storage you can skimp on specs to some extent. I prefer to use cheaper drives like the SanDisk cloudspeed eco line for a bulk storage pool and whatever high IOPS+endurance drives I can find cheap for my VM host pool. When you split your pools you can do things like use mirror zdevs for performance for VMs and raid z whatever for bulk storage.
How many drives are you looking to use, what are they for, what interfaces do you have available on the machine (SAS backplane, SATA, any number of available NVMe hookups of some flavor, etc), what pool topology are you trying to use and what is the intended workload you want to jenga tower off of all of the above? With more info people can give you more specific recommendations. (E: and what sort of machine are you running things on while I’m at it, processors and amount of RAM would be useful)
