Are these retail boxed drives or were they pulled from external enclosures?
They are retail box purchased for corporate data solutions. I assume this question is to know if they are bootable with uEFI and yes they are.
I also have access to surplus from the same project of WD 5tb drives. I do not yet have a price on them as I only have one atm with 4 more coming in later today.
If you have larger quantities or looking for some other type of drive like the 2tb or 3tb Xts, let me know as I can arrange such deals.
