Major Kudus on this. A very comprehensive but easy to understand layout of storage and technology. The only change I would suggest is the Enterprise drive versus Desktop/NAS class drives although WD Red drives do have the feature. The Enterprise drives have the Error Recovery Control which in WD lingo is TLER. This feature is something all the drive manufacturers restrict normally to their Enterprise drives firmware simply because they want Large raid clients buying mass amount of enterprise drives for their storage needs. What this equates to in the raid configurations are controllers marking drives bad and out of the raid volumes prematurely simply because the drive is not responding during a repair operation. If that operation takes to long or there are to many bad blocks in that location to repair in time, the Controller thinks the drive is bad since it's unresponsive and marks it out of the raid. This puts the raid into degraded state prematurely since it really was just a drive repairing block data in bad block areas. Enterprise drives will timeout that function before the time period expires based on the controllers or controller settings. Some controllers have management settings that allow you to change that timeout period. Either way this issue has become exasperating over the last couple years since drive manufacturers are shipping drives with so many bad blocks and it doesn't seem they are marking them out at the factory anymore. I know the cost of Enterprise drives is significantly higher than desktop drives when buying bulk but this issue can cause a raid and client no end of headaches. Parity raids are far more likely to run into this than mirror block based raids. So as a general rule if Parity always get Enterprise and if Mirror then you can look at Desktop but I still don't recommend it. Those with questions on this can reference some info here:
