WinBench 99 Version 2.0

Business Disk WinBench 99

The improved 2 TB Western Digital Caviar Green (WD20EARX) did poorly in this test, actually coming in much slower than its predecessor, the WD20EARS. This is partly due to its slower spindle speed, even though both drives are officially similar with the sole difference being the SATA interface.
