WinBench 99 Version 2.0

Business Disk WinBench 99

The 3 TB Western Digital Caviar Green did well in this test, delivering a 6.7% better throughput than the older 3 TB Caviar Green. However, it was still significantly slower than the 2 TB Western Digital Caviar Green AFT and the 2 TB Western Digital Caviar Black.

High-End Disk WinBench 99

It actually did better in the High-End Disk WinMark 99 test, coming at at second place, just behind the 2 TB Western Digital Caviar Black - a 7200 RPM hard disk drive.

Transfer Rate Range

This chart shows you the range of platter-to-buffer transfer rates from the innermost track to the outermost track. In other words, it shows you the range of disk transfer rates of the hard drives (from minimum and maximum).

The new WD30EZRX is definitely faster than the older WD30EZRSDTL, or at least our first-generation model. As both models use 4 platters with the same areal density, therefore, the only reason for the higher throughput is a higher spindle speed. The good news is Western Digital apparently quitely increased the spindle speed for current WD30EZRSDTL drives as well.

The increase in spindle speed puts the new 3 TB Caviar Green a tad ahead of the older 2 TB Western Digital Caviar Green AFT hard disk drive. Both these drives have the same throughput at the outer tracks, but the WD30EZRX won at the end, due to its better performance at the slower inner tracks.
