Western Digital RE2-GP: WD7500AYPS

 

Here is a “green” drive from the server-oriented RE2-GP series. It is funny how Western Digital declares the spindle rotation speed of these HDDs. While this parameter can be easily found among the specs of every other model, it is either not specified for the Green Power disks at all or hidden behind the term IntelliPower that doesn’t offer any specific number. It looks like Western Digital is ashamed of confessing that the platters of these HDDs are rotating at 5400rpm. At least our tests indicate clearly that the spindle speed of this HDD is not variable (as had been rumored in some news articles before the release of the Green Caviar series) but constant and equals 5400rpm.

We’ve got two HDDs from this series for today’s test session: WD7500AYPS and WD7501AYPS. Note that these HDDs feature a 3-platter design but have only 16 megabytes of cache memory.

We received this drive just before we began our test session and the Western Digital website refused to tell anything about it (as opposed to Google). We don’t know if the change of the nomenclature is due to firmware changes, new platters or new electronics or all that together. Anyway, we are more interested in any changes in the speed characteristics of the HDD.
