D_Know_WD :
These parameters could indicate some mechanical flaw.
One thing you can try is to just attach the drive with different cables(both SATA & power ones) to a different SATA port and re-test. See if you will get different results.
Another thing you can do is to go to Resource Monitor and see if you get high disk usage and what is causing it.

I am sending a copy of what the SMART software I'm using says is going. The numbers keeps changing and when the drive is under load it starts to freeze. If the drive was a person I'd think it was crazy in how it fine one second and coming to a crawl the next. I tried changing the cable and where it was attached to on the MOBO with no effect. Changing the power cord is not an option I'm lucky I have the one connector. Its a dell. They are not generous with extra connectors. sorry about the format I tried to correct multiple times.
