Please suggest the best readyNAS unit for this hard drive

Thanks a lot for your replies PapaBear and mdgm. I will return the ST33000651NS drives if I end up having compatibility issues and will get the nearly identical ST33000650NS instead (which is on the HCL). But regardless of compatibility my real question was if any of the NAS units would be bottle-necking a 3 TB SATA 6 GB/s hard drive. I have my eyes on the Ultra 6 or 6+ as I am just a prosumer. But if you tell me that I will see a noticeable increase with a business class then I might make the leap. The reason I thought to ask is because the drives I am getting are 3 TB and SATA 6 GB/s instead of a more standard desktop drive that's 500GB and SATA 3 GB/s... I just want the flashy drives I'm spending the extra bucks for to not be bottle-necked because I didn't go business class.

TL;DR:
If one of you could confirm that a 3 TB SATA 6 GB/s drive (on the HCL) would operate at the same or close enough to the same speed in a Ultra 6/6+ vs a business class NAS that's all I need to hear!
Sorry for the lack of expertise on my part. I feel like this is a question I should be able to answer confidently on my own but I get a gut feeling that at my level of knowledge I might be missing something.

[Edit]
PapaBear, you said you couldn't find the drive I mentioned. Just in case you were curious, I decided to add links to the product pages for the two drives in question. Just for your own info is all.

1. Here's the drive that's on the HCL: http://www.seagate.com/ww/v/index.jsp?vgnextoid=6a0505f79edac210VgnVCM1000001a48090aRCRD


2. Here's the drive I bought that is not on the HCL: http://www.seagate.com/ww/v/index.jsp?vgnextoid=b0942191077ec210VgnVCM1000001a48090aRCRD
