My min transfer is 4.4 mb/s. I saw other tests using my hard drive and hd tune and their graphs don't spike like mine. I tried changing sata cables, changing ports but that didn't help. What could be wrong with it?

Are there other programs (such as virus scanners, for example) accessing the drive? Any concurrent access by multiple programs is likely to cause a lot of seeks which can drastically lower performance.
This is another reason to double-check the Chipset Driver version
you are running currently.
Along these same lines, it wouldn't hurt also to double-check
the HDD's jumper default: according to WD's Jumper Specs,
the lack of any jumpers defaults to 300MB/second. So,
check to see if there is a jumper on pins 5 and 6:
Thanks for the suggestions everyone. I just went ahead and bought another wd black 1tb at frys. The stuttering is gone and my system is pretty snappy. HDtune benchmarks are also normal. No erratic spikes. My min transfer rate does not dip below 55mb/s like the 1tb I got from newegg. I guess I just got a bad drive.
