For a desktop hdd use, they will be about the same, the red has some nas features, but won't be needed in a desktop.
 
THe red pro is 7200, the red plus is cmr.
 
Id also look at the seagate barracuda drives, there about the smae
 
Cause its smr, so its much slower in extended random writes, probably won't affect you here, but can be very slow in a raid rebuilt
 
 

For standard data storage, a Blue is fine. Red drives are designed for NAS operating where they're on 24/7 in a server next to other drives. They have extra protection against vibrations and features like TLER which helps with some specific use cases in RAID.
 
Standard Red drives are 5400 RPM, while Pro drives are 7200 RPM. Standard Red drives are also SMR, while Plus and Pro are CMR.
 
WD60EZRZ is EoL. NewEgg is a marketplace, so the prices don't necessarily reflect RRP or the real value of the drives.

SMR (shingled magnetic recording) and CMR (conventional magnetic recording) are different ways in which the write heads of the drive operate. For reads, both are fine, but SMR drives suffer from comparatively poor write speeds. It's difficult to explain it in a short post, so here's some resources if you want more info.

It's come to people's attention recently as WD has been called out on using SMR on some of their Red drives without being upfront about it, which they have now admitted and state which of their drives are SMR and CMR on the WD Red product info pages.
 
EoL means end of life, yes. The WD60EZAZ is the replacement for the WD60EZRZ, which WD no longer produces.
