M.2 SSD for ZFS

[egli]

Dear all,
I want to build a Proxmox home server based on a Ryzen 9 3900X. For the motherboard, I have chosen the Asus PRO-WS-X570-ACE as it offers a X570 chipset and supports ECC RAM. It has two M.2 slots. Those I would like to populate with two SSDs each 1-2 TB to use in a ZFS cluster.
I found the well-cited list.
https://www.sebastien-han.fr/blog/2...-if-your-ssd-is-suitable-as-a-journal-device/
here in the forum. Unfortunately, all devices listed there are 2.5" SSDs.

Can you recommend me any good M.2 form factored SSDs? Initially, I was thinking to use two Samsung 980 PRO SSDs. However, I am a little unsettled as Sebastien argues heavily against using prosumer SSDs.

Can you recommend any M.2 SSDs that are suitable for ZFS?

Peter

2.5" doesn't mean that it is slower than M.2. You get alot of fast 2.5" U.2 SDDs that use NVMe too and can be connected to a M.2 slot by using a M.2 to U.2 cable:

Usually all M.2 SSDs are quite bad compared to U.2 models, because the M.2 footprint is just to small to allow a great write endurance and powerloss protection while still offering enough of storage.
