I just want readers to be aware of what's listed here. This isn't the original 1TB version. Also, consider that £85.59 = $95, and Amazon is currently selling the 1TB Seagate Storage Expansion Card for $200. "Half Price" for half the 1TB card Seagate Card is not particularly special in terms of $/GB.

Should be the correct one to play series x on?
