ReadyNAS Device Compatibility List

I was thinking about buying some 2TB Seagate Constellation ST32000644NS drives. I currently have and have been happy with the Barracuda ES 750s in my NV+, and for 2TB drives, the model I've listed above seems to be the "replacement" model. I see that they are listed as compatible on the ReadyNAS NVX and Pro models, but they are not listed for the NV+. Does anyone know why they might not work in the NV+ or whether they just have not been tested and should likely work? If they were listed, they would be the only 64MB cache and Anti-vibrational 2TB drive with a 5 year warranty.

Thanks!
