I'm thinking he is intending to use the SSD he just received for his OS and programs, one of the WDs for his internal data drive, and an external dock for his backup drive. I personally like the WD Blacks for their longer warranty but I agree a Black is overkill for a backup drive. I would suggest getting two Greens instead of a Black for the backups. It is much safer to have two identical backups so, if one backup drive should fail (it happens), he will have another one to fall back on.
@ OP. Orico makes some nice docks. Just peruse Newegg's or Amazon's selections and choose one you like the looks of that gets good reviews.
