I currently have a 1TB My Book Studio II that it set up in RAID1 mode. Does anybody know if the case/housing design or RAID card in the new 4TB version is any different to the 1TB model? I was thinking of buying 2x2TB WD Green Cavier drives and installing them into my current MyBook Studio and using the current 2x500GB drives in my pc.
I had the same question but when I found the 4 TB drive offered for US$419 from Beach Audio (others as well) the cost difference between the two 2 TB drives and the overall package w/ enclosure is US$20. With only a $20 delta I simply purchased the 4 TB offering and didn’t bother to resolve the question.
That said the manual for the 4 TB drive suggests that any WD green drive can be used the enclosure.
I just installed 2 2 TB WD Caviar Green drives in my original 1 TB My Book Studio Edition II, and it worked like a charm, with automatic RAID 1 restore. However, my problem is that currently the extra space is not available - I posted a separate thread on this.
But I can confirm that you can install bigger WD Caviar Green disks in a My Book Studio Edition II and it should work.
