Replacement drives for Thunderbolt Duo?

The user guide for the My Book Thunderbolt Duo indicates only WD Green drives should be used. However, it looks like the Green drives no longer exist (discontinued or now included in the Blue line?). So what are the supported replacement drives for this enclosure?

Context, I have a 6TB (2x3TB drives) Thunderbolt Duo that I’m looking to upgrade the storage (replace both drives with higher capacity). I’m wondering if I could put 6TB Blue or Red drives in it successfully.


Hi, I have never done this, lets see if another user can provide some information or guidance.

Hi any one can share if 6TB thunderbolt Duo could be upgraded to 8TB? I have the same issue where 1 of the drive failed.
