February 6, 20242 yr I am doing some testing to figure out how I want unraid formatted. This is my first unraid install but I have watched many of space invaders videos. I have a windows image backup folder(15GB) I tested transfering to a ZFS drive and a XFS in the same array from a unassigned nvme ssd. I also have turbo write speed enabled as well. You can see in the screen shots that XFS is about double the write speed of ZFS, is this normal? Also I do not have encryption and compression on...would having compression turned on help speed up ZFS? FYI both drives are shucked 12TB WD reds and have the following info: Model family:Western Digital Red Device model:WDC WD120EMFZ-11A6JA0 LU WWN device id:5 000cca 29bdb96dc Firmware version:81.00A81 User capacity:12,000,138,625,024 bytes [12.0 TB] Sector sizes:512 bytes logical, 4096 bytes physical Rotation rate:5400 rpm Form factor:3.5 inches Device:In smartctl database 7.3/5528 ATA version:ACS-2, ATA8-ACS T13/1699-D revision 4 SATA version:SATA 3.2, 6.0 Gb/s (current: 6.0 Gb/s) Edited February 6, 20242 yr by ksullivan86
