WD AV-GP: WD10EURS-630AB1 (1 TB)
Now we’ve reached traditionally numerous products from Western Digital. First goes the rather rare AV-GP model with a capacity of 1 terabyte. It is a special series of HDDs optimized for home audio/video appliances. We guess it should be no different from ordinary energy-efficient HDDs save for firmware. You will see that in our tests.
WD Caviar Blue: WD10EALS-00Z8A0 (1 TB)
We haven’t reviewed Blue drives from Western Digital for a while. According to the company’s policy, this series includes somewhat outdated products that do not compare well with newer HDDs but can still be produced for some time. This 1TB model has a cache buffer of 32 megabytes. We wonder how much it is different from its high-speed Black counterparts and how many platters it has.
WD Caviar Black: WD1001FALS-00E3A0, WD1001FALS-00Y6A0 (1 TB)
We can’t omit the Black series, of course. About half a year ago we compared different versions of the 1TB Black model and found that it had inconspicuously transitioned from 333 to 500GB platters. And now we’ve got another change in the letters: the familiar E3 subseries is complemented with an Y6 one.
