4 TB My Book one HDD

Dear WesternDigital, I would like to know if you are planning to release a new external storage My Book in 4TB (4TB on one hard drive) version in this year. Thank you very much for your quick answer.

Probably, as soon as 4 TB drives are available.

I hadn’t been keeping up with advances in desktop hard drives, so I was astonished to discover that the 3 TB MyBook contains but a single drive.  The last time I built a machine, the biggest you could buy was 1 TB.  Amazing.
