What are Ultrastar drives?

Ultrastar is Western Digital's data centre drive line: helium filled hard drives from 10 to 22 terabytes and more, rated for 550 terabytes a year and 2.5 million hours between failures, in SATA and SAS. They are the drives for servers, SANs and large arrays that work all day, and the wrong drives for a desktop, where their duty rating is wasted.
