    I currently use a 4TB WD Thunderbolt Duo. I bought the unit a few months back thinking it would easily be upgradeable to 6TB or 8TB. I now need more storage space, and with the new 4TB WD Green drives now available, I'd like to upgrade my 4TB unit to 8TB.

    Has anyone upgraded their 4TB Thunderbolt to 6TB or 8TB ? I ask because people at WD tell me upgrading to a larger capacity drive might not work and they recommend against it.

    I'd like to hear from users who have tried it. Thanks in advance.

    Robert

    I got the same unit and was considering doing the same thing. I would be interested if someone has done it as I do have some 3TB disks which I can use. I can't see a problem with upgrading but it would be good to hear from someone else.

    Well, of course they do. Selling an 8TB Thunderbolt Duo makes them way more money then just upgrading the hard drives.

    Pop open the top, install two of the 4TB WD Greens (or 4TB WD Reds for $10 more if you run them 24/7) and watch what happens.

    you should be able to replace the drives with 2x 4TB drives. However, I would find out if you can in fact use the Red Drives. I only mention because I have an older MyBook Studio II and I can only use WD green drives in it and no other model from WD.

    cannot be done. you can only use the same type of original (non red) drives as confirmed by Anand. as to if you can up the capacity, no idea.

    I went ahead and installed two 3TB Green drives in my unit. It took all of 30 seconds for WD Utilities to configure my new 6TB Thunderbolt Duo as a RAID 0. Works like a charm. Upon startup the new drives had a JBOD status.

    Now for really interesting info: my 4TB Thunderbolt Duo had two 2TB Red drives installed in it. This is a brand new unit I purchased from a WD-approved major online store about 4 months ago. I think Giuly is right. The unit—mine, at any rate—works with both Red and Green drives of various capacities.

    Red drives come standard in the WD Thunderbolt Duo "NAS".
