Hey Sir Milo Gaming,
As Keemann said, WD Black drives are indeed among the best drives on the market. They are particularly designed for gaming and high-performance workstations and deliver great speeds and fast load times when it comes to gaming. Western Digital has always been a reliable company for Hard Drives.
The build that you posted seems pretty massive and the WD Black would serve as a great addition to the 500GB SSD.
Hope this helped,
Captain_WD.
