3TB drive compatibility?
I own a ReadyNAS Duo with a pair of 1.5 TB drives. It is starting to get full so I am considering upgrading the drives. I could upgrade to 2TB drives, but that seems like a lot of cost and effort f...

Interesting point, TeknoJnky, I think you worry too much, especially if you upgrade the CPU to an E6600 from the stock E2160 to decrease resynch times ~50% (not to explicitly advise this, as it violates warranty, and I know I for one want my warranty but some dont care--but I've read it works like this)
I say u worry 2 much because I've built 4 of these Readynas pro systems loaded with WD20EADS 2Tb green drives, and in all 4 I've yet to have even a single drive failure in about 2 years among the 24 drives as long as WDIDLE3 /S0 and WDTLER (TLER-ON) are used--if you dont enable these utilities, sure your drives will croak fast, watch for 200,000+ LCC's on old drives that are misconfigured! A few thousand LCC's are nothing for a well used but still super-reliable drive. These drives are super-reliable, and I expect the 3Tb Wd30EZRS to be the same or better if you use the WDIDLE3 /S0 setting on it (TLER doesnt work on the new WD 3Tb drives at least so far) plus the 3Tb drives are faster.
Yes, you're right the loaded wd30EZRS system has 13.5 to 13.6Tb capacity - tried building one this weekend with a buddy this last weekend (we needed to pool our drive resources to get all six WD30EZRS units) and it does work with all 3TB drives if you factory default with all six WD30EZRS drives in place to get about 13.5 Tb of usable capacity. Supposedly you can xraid2 "in-place" upgrade from six Wd20EADS drives, replacing one at a time and resynching, with up to 4 Wd30WZRS drives (then you have 2x2TB drives and 4x3TB drives) without factory defaulting.
