WD Caviar Black: WD1501FASS-00W2B0 (1.5 TB)
We have taken the 1.5TB Black model for this review, too. We have not tested it yet and are very interested in learning how it performs because its 2TB cousin delivered excellent performance in our earlier tests.
WD RE4: WD1503FYYS-01T8B0 (1.5 TB)
It has become a tradition for top-end HDDs from Western Digital to come to us in pairs: a desktop model is accompanied with its server-oriented counterpart. This time around, we’ve got a 1.5TB model from the RE4 series.
WD Caviar Green: WD20EARS-00S8B1, WD20EARS-00MVWB0 (2 TB)
Last go 2TB models from the Caviar Green series. These feature Advanced Format, i.e. 4KB physical sectors. We hope you have already got acquainted with that technology from our previous reviews, so the more interesting thing is the change of the index from S8 into MVW. As far as we know, this change should denote a transition from 500 to 667GB platters and from 4 to 3 platters per HDD.
You can find the firmware versions of the tested HDDs in the following table:
You should keep it in mind that the performance of HDDs may vary depending on what firmware they have.
