Because that disk has already been used for the boot device.

TrueNAS requires you to have a dedicated device for the operating system's storage. We recommend the use of a small SSD, maybe 60GB or 120GB, for this purpose. You will notice that the 8TB disk you have is assigned to "boot-pool" and is therefore unavailable for use in a different pool.
