These aren't home drives, where you have ample cooling in a PC case and power.

These are for NAS's/Servers where power and heat is a controlling factor, if admins wanted/could they would buy the 7200rpm drives and there would be a market for it, but they chose the 5400rpm because of constraints.

This is WD being lazy/cheap. Instead of selling them as 7200rpm drives, they're shovelling them into the 5400rpm lines as a presumably cost cutting measure.

They did not learn their lesson with the SMR/CMR scandal. Label your drives clearly.
