SOLVED Drive backup using mirroring: how to restore? Hello! My setup is the following: 1 vdev with 3 HDDs, all 3 mirror of each other (so 3 x 3TB HDD, total available space = 3TB) 2 Drives are just going to spin all the time, mirror of each other, that's the redundancy The 3rd drive, I'll plug it in once every now and then (say: once per
- SOLVED - Help understanding Mirrored vdevs in relation to pools
12 disks in 6 mirror vdevs give you the IOPS of 6 disks At the expense of less resiliency - one disk is easy peasy, lose two disks and you might still be ok, but as soon as you lose an entire vdev, the pool is toast So your assumption about the right three disks failing is correct
- Some differences between RAIDZ and mirrors, and why we use . . . - TrueNAS
ZFS is a complicated, powerful system Unfortunately, it isn't actually magic, and there's a lot of opportunity for disappointment if you don't understand what's going on RAIDZ (including Z2, Z3) is good for storing large sequential files ZFS will allocate long, contiguous stretches of disk

Everywhere, everybody in every blog post looks telling that mirror vdev Is Better than raidz vdev If that's Always the truth, why do Raidz even exists? What are the pros of using raidz over mirror ( with same number of redundant disks)
- 3 Drive Configuration | TrueNAS Community
The drive prices for 16TB drives (specifically Exos) are pretty decent compared to 10TB I think, thus why I want 16TB Are there any downsides to a 3 way mirror? Would it allow two out of the three drives fail without incident? Also if you know any documentation on it that would help a lot Also with RAIDZ, adding drives to a pool later requires resilvering, does a mirror 3 way mirror require
