> Because if you need a hard drive This is the third such major scandal from WD in as many years. First, selling SMR drives as CMR. Second, selling 7200RPM drives as 5400RPM. Now this. They've lost a lot of credibility, and I don't see any of the other manufacturers having issues rivaling WD.
> selling 7200RPM drives as 5400RPM I suppose you mean the other way around? Otherwise, what's the problem with selling a higher RPM device as a lower one? Isn't higher RPM better? (Genuine question, I don't know much about HDD).
They also draw more power, which might mean they simply don't work properly in some low-power devices, or mean that any UPS someone might have one connected to will not last as long as they expect during a power interruption.
