Hello!

I'm going to be running my first virtualization server using Proxmox 7, and I'd like to keep the OS on a pair of 2.5" SATA SSDs in ZFS RAID 1 configuration.

I've got a pair of Lexar NS100 512GB SSDs I was going to use to get started, but I've run into a problem with TRIM. The hardware apparently supports it, according to `smartctl` and `hdparm`, but `fstrim` says they don't support the `discard` command.

I could very easily see Lexar putting out an SSD at the low end that supports TRIM when the Windows utility is installed, but doesn't support it under Linux using standard tools.

So, I need to pick up a pair of high-endurance, low capacity 2.5" SATA SSDs that will work for this purpose. My size options (thickness) are "7mm to 9.5mm."

I'd prefer to buy used enterprise SSDs, as so far that's gotten me higher endurance at lower prices.

Any suggestions?

Thanks!

Hi!

Looking to buy a pair of 1tb SSDs for proxmox for a RAID 1 setup. What are some good entry level enterprise grade SSDs that I can expect a few years of worry free use on? I dont know much about the differences between enterprise & consumer SSDs, but I've read enough to know that I should care to use the better disks for the long term.

I'm looking to replace an old 2.5 laptop hardrive in my minipc used as backup storage. Proxmox has been throwing warnings for the drive.

• Proxmox OS and VMs run on a 1TB Kingston internal NVMe

• Two external 1TB USB SSD's for VM backups, VM data, media, and VM docker data

The internal 2.5 drive is strictly for additional backup, and won't be storing the OS nor live VMs. I'm looking for decent ssd drives sold off Amazon that:

1. Aren't slow as molasses

2. Reliable

3. Are a decent price range

Any suggestions would be appreciated.

EDIT

Took the advice and ordered an enterprise device

I've been looking at various NVMe SSDs and I can't fully get a picture of what's worth purchasing. I have brought a 2TB Crucial P5 Plus, but looking at storagereviews (linked below) isn't not looking the best, when you look at the SQL test. Since I'm using the disk to run multiple VMs.

Would I be better exchanging it for another NVMe drive, or am I worrying about nothing here? I would buy a DC grade NVMe but those are very expensive in the 2TB capacity mark.

I was looking at exchanging it for a Samsung 970 Evo Plus, but I've read there maybe hardware issue with cache design on that model, people seem to get varying results.

I'm using the NVMe disk in a PCI3.0 slot, so 4.0 isn't required, only got the Crucial P5 Plus because it was a good price.
