1. Buy or Organize a new Disk with the same RPM and the same or Bigger

is bigger than c5d1 then any excess will simply not be addressable by
ZFS. Which is not be an issue if it is just a couple of GB. If you wish
to have two new disks as you final configuration then just grab any two
disks you like or even SSD's. The main assumption is of course that any
disk you pick fits your physical Plugs.
I thought the sector size should match else it causes a performance problem.
Even worse, I think that zfs will refuse to use the disk if its
underlying sector size does not match the current vdev.
It should be possible to purchase 512N drives (vs 512E where E =
"Emulation") for a long time, but it is necessary to be cognizant of
what one is buying. Besides zfs, the BIOS may care about this.
When considering boot drives, don't buy larger drives than you need
(boot drives should be for booting and data drives should be for
data), but also be aware of small drives on the market which are
basically rotting junk because they are so far behind the technology
curve.
