Western Digital Caviar Blue: WD7500AAKS
This HDD used to belong to the Caviar SE16 series some time ago but then Western Digital decided to diversify its HDD line-up and offered as many as three Caviar series. This HDD fell into the basic, blue, series. Besides it, there are a high-performance Caviar Black and an economical Caviar Green series. The latter includes 3.5-inch HDDs with a spindle rotation speed of 5400rpm. This is the company’s innovation as all desktop HDDs used to have a spindle speed of 7200rpm for quite a long time. This return to the past is meant to reduce power consumption, which is the main feature of all “green” HDDs. As for the Black series, it is going to deliver the highest performance of all. So far, we have only got a Caviar Blue. The Blue series seems to include rather old models with not-highest recording density that offer an “optimal combination of price and quality” as the marketing folks like to call it.
The Caviar Blue and the server-oriented model from the RE2 series are based on four platters.
Western Digital RE2: WD7500AYYS
Why leave Seagate’s enterprise drives without competition? Western Digital is quite competitive as it produces a pair of a desktop and server model at each step up the technological ladder.
