The 2tb main drives (main and data) are what they classed as 'enterprise grade' but the failed one was just your common drive and was the data drive from the previous build so it had some operating hours on it.
Way back when in the days before MS-DOS 5 my office machine had a gigantic 15mb hard drive and monstrous 640mb of ram. (The machine actually had DOS 3.3 but I couldn't find a catchy video for it.. ;-)
I’ll take it.
