I'm getting some odd/poor performance from a new build with an WD6401AALS. My spec's are:

Intel Core i7-860
Gigabyte GA-P55M-UD2
Kingston 2GB PC3-10600 x 2
Windows 7 Ultimate x64

I've updated all the drivers and set the following options in the bios:
SATA Port0-3 Native Mode = Enabled
Onboard SATA/IDE Device = Enabled
Onboard SATA/ED Ctrl Mode = AHCI
The drive is plugged into SATA 0 and not GSATA0

Is there anything I messed up or something I'm missing? Any help would be greatly appreciated!

I wouldn't worry about the WEI. I'm getting a 5.9 as well with a V. Raptor and it really doesn't matter much by way of every day performance. Windows 7 is set up to only give above a 5.9 with solid state drives (for the most part). If you want more performance and better numbers, go with a SSD. Otherwise than that, I'd say you are fine, as the WD Black (that's what you have, correct?) is a good performing drive, regardless of what Windows says.

If that 640GB is your system drive where Windows is also installed, then it looks perfectly normal to me.

HDDs are 100MB/s when doing sequential I/O and between 50KB/s and 1MB/s when doing random I/O (seeking). As you use a mechanical drive as a system drive; that means you have to seek; hence the spikes towards 0MB/s.
