" Telling customers you’re selling them a 5400 RPM drive when it’s actually a 7200 RPM drive could cause problems if the hardware that drive is intended for can’t dissipate the additional heat or provide enough power.

This is the second time in a year that the company has misrepresented the hardware that it’s shipping to customers. True, in this case, the situation arguably breaks in the customer’s favor — but that doesn’t make it a good idea for companies to play fast and loose with specifications. "
