Thanks. I am new to ZFS/RAID. I was basing my basic understanding on RAIDZ5 and assumed ZFS works similarly. In a sense, if I don't dedicate a parity drive in my ZFS pool, would that mean it will automatically run at the slowest speed drive (SN850)?

This should be a quick question. I plan to have 1 ZFS SSD Pool with 1 parity to permanently store [appdata, VMs, SMB, etc] in FAST storage and another cache pool for regular media downloading and anything else that will be moved to array. I have the following SSDs with the following endurance (TBW) 2X 2TB SN850X Gen 4 SSD @ 1200TBW 2TB SN850 Gen 4 SSD @ 1200TBW 2TB Intel 670p Gen3 SSD @ 740 TBW Since the Intel 670p has lower write endurance (and much lower speeds) than the other 3 drives I have, which would be the best configuration (examples below). Option 1: ZFS RaidZ1 pool: 2x SN850X w/ SN850 as parity AND Cache Drive: Intel 670p Option 2: ZFS RaidZ1 pool: 2x SN850X w/ Intel 670p as parity AND Cache Drive: SN850 Option 3: ZFS RaidZ1 pool: SN850X + SN850 w/ SN850X as parity AND Cache Drive: Intel 670p
