Which SSD? Lexar NM790, Western Digital WD_BLACK SN850X, Samsung SSD 990 PRO

Since my system often shows high I/O utilization, I would like to partially replace the existing HDDs with M.2 SDDs.

What would you use for this? The plan is to use 2 x 4 TB SSDs as a mirror.

* Lexar NM790 4TB, M.2 (very cheap, TBW 3PB)
* Western Digital WD_BLACK SN850X NVMe SSD 4TB, M.2 (expensive)
* Samsung SSD 990 PRO 4TB, M.2 (even more expensive)

Because of the cheaper price I would take the Lexar. I've already ordered two of these, but one of them doesn't work. Now I'm unsure whether I should perhaps switch to more expensive models.

The Proxmox system (mainboard FUJITSU D3348-A2 S26361-D3348-A2, 128 GB ECC RAM) is privately operated. It runs 24/7. Around 20 LXC containers (Nextcloud, mail server, VDR) and two VMs run on it.

Best regards

Tony

Jup, google for "MZ1L23T8HBLA-00A07", "MZ1LB3T8HMLA-00007" and "MTFDKBG3T8TFR-1BC1ZABYY".
But they all require a 22110 M.2 slot and cost ~455€.

I dont recommend M2 (NVME) drives, because it doesn't have "hot-swap" function at all ( unless you using with HBA/RAID card between ).
Use SAS SSD for that (Samsung PM series).
