Doesn't matter whether that piece is used predominantly by marketing or not, it is a defacto contract that cannot substantially depart from the legalized warranty verbiage. > >> I *think* it's a 24x7 drive also but I could be wrong. > > There is no such thing as a "24x7" drive or not.

Yeah that's more of a marketing term for sure, but in determining the drive warranty, how much it's doing the various things it does is a significant factor. It's not at all the same thing to take a 2.5" laptop drive and run it 24x7 without it ever spinning down. Just like it's not the at all the same thing to take an RE drive and have it spin up and down 15 times a day… like a laptop drive.
