Switching to Seagate 8TB IronWolf NAS disks

Time to replace my NAS disks, as storage space runs low, and my 6TB Western Digital drives are now out of guarantee. And I know they die on a regular basis.

This time I decided to go with Seagate IronWolf disks filled with helium,
lets see. at least they seem to also provide good RMA just in case.

After that the available space did automatically jump from 20.3TB to 29.1 TB, due to zpool autoexpand feature turned on.
