WDC_WD60EFRX-68L0BN1 vs WDC-WD60AFA-68SHWN0 Do you believe it is reasonable for customers to see this and expect that a drive called "WD 6TB Red" when you purchased previously and when you go to purchase it now, that are described identically, with no way to purchase the previous model, and know that the fundamentals of the storage medium have changed and completely flip it's performance characteristics? Especially when the drive is specifically marketed as being RAID and NAS friendly - one of the primary differences between the Red and Green drives is disabling some of the sleep power saving mechanisms that are known to cause issues with RAID arrays. And they make it so that the drive is largely unusable in any parity based array? When minor revisions, updated firmware, etc., will result in minor changes to model numbers all the time? Because, well, I don't.
