Hello
I am new to NAS systems.
I want to build an energy-efficient NAS.
The plan is to use TrueNAS Scale with 2x12TB and maybe later upgrade to 4x12TB. I would operate this in RAID 1, then after the upgrade in Raid 10.
I was thinking about maybe using an ASRock N100M and if I plan to upgrade to a PCIe 3.0x1 to 2x SATA adapter is that even possible or am I missing something.
Or should something more powerful be used such as Intel Core i3-12100T/10100/… Then the problem with the Sata ports would no longer be a problem.
I would use a small NVME SSD on which I install TrueNAS Scale.
Which 12TB HDDs would you use?
Your two drives would be Mirrored and then you would be adding a second VDEV of two drives Mirrored all in one pool. We don’t use the terms RAID 1 nor 10.
It’s best to pick a motherboard with enough SATA ports for your disks and avoid SATA expanders. Some may work, others fail with ZFS / TrueNAS.
Stick to NAS type hard drives that use CMR for recording tech. Avoid any drives listing SMR.
