[TUTORIAL] Proxmox ZFS raid1 performance

[aaron]

Most important if You use ZFS: buy SSD with PLOP (performance 2-2.5x !!!)

Using SSDs with PLP (power loss protection) is a good recommendation in any case where you are expecting continuous utilization.
Consumer/Desktop SSDs are geared towards bursty write patterns.

Sorry. Dictionary in my Phone made bad things sometimes. I mean PLP technology - capacitor on SSD Drive. That allows to scream by ssd "write done" before it is done because it save.

Check pvestat command on both drives.
