Wd my book live duo disk replacement

Good evening,

I have a WD My Book World Edition II, and it comes with 2x2tb disks…i would like to know if i can replace one of then disks for a wd 4TB and still construct a raid.

Thank you!

Hi, I don’t recommend replacing the internal drives with other that are not of the same model as drives that were included, since this is not supported by WD. Using larger drives of different models might not work.

Thank you for your answer! I only want to upgrade one, thats all! and are the same model, WD GREEN
