How do I know if it is necessary

If it's a used disk it may be. If the NAS produces an error (e.g. corrupt root) on installation it's something I'd try.

I have read it could take all night for it to do this on the first drive.

With one drive it shouldn't take too long. With multiple drives, the syncing sector by sector takes a while, but not as long as adding the drives one by one.

It will be a brand new drive out of the box, is it necessary?

NAS should initiate factory default automatically then.

The data will need to be added to the two WD Greens before I can add the Hitachi's to the mix because they have data on them that I need to move to the array. So I figured I will install the two brand new WD Green's, drop the data on the array, then delete the partitions from the Hitachi's and add them to the array. Then I can replace the Hitachi's with WD Greens one at a time as funds allow.

Sounds like a good plan.
