Avigilon HD-NVR2 Uses Outdated Dell R710. Why Pay More Than The Latest Dell Offering?

Avigilon Cameras are great. The HD NVR they offer with capacities 3,5,15,21 etc. are using Dell PowerEdge R710 loaded with 3-21TB configured as RAID 5. I am presuming they have taken same old R710 and changed the logo. Or are there any upgrades or changes made? Why should a customer pay a much higher amount for the older dell series when the newer R720 with latest and better configuration is available at a much cheaper price.

Another question I have is that the 15 and 21TB models are using SATA HDDs configures RAID 5 in the same server. Is this a recommended scenario?
