Overall, I argue that the enterprise drives we have are treated as well as the consumer drives. And the enterprise drives are failing more.

So, Are Enterprise Drives Worth The Cost?
From a pure reliability perspective, the data we have says the answer is clear: No.

Enterprise drives do have one advantage: longer warranties. That’s a benefit only if the higher price you pay for the longer warranty is less than what you expect to spend on replacing the drive.

This leads to an obvious conclusion: If you’re OK with buying the replacements yourself after the warranty is up, then buy the cheaper consumer drives.
