>Any significant difference between consumer and enterprise ones? I am looking for reliability (use case is backup)
No, other than SMR (shingled) vs CMR (conventional) both types of which are present in Enterprise & Non-Enterprise Drives. In theory, shingled drives are cheaper but in the real world are basically the same $/TB and carry performance penalties of 20% in sequential read/writes:

Otherwise WD & Seagate are NOT spending millions of dollars running separate factories to assemble different lines of special drives for different customers. It's all the same spinning discs inside just with different certifications most of which don't matter to end users. For reliability sake in theory if you pick a drive that meets your capacity needs using the least # of platters (and therefore smallest number of read ahead motors and actuators) you'll have the longest lifespan but again that's theory and you're still at the mercy of the Law of Large Numbers.
