Slow hard drive possibly failing?

I built this system March 20 2015, it has perfectly fine except for a faulty power supply that would fail whenever it would be put under load, after a while my harddrive would act weird, simple tasks on windows would max out its usage and the transfer rate stuck at around 20mb max... i am guessing that it is failling and have come to see if anyone has a different opinion about what may be happeneing. I benchmarked it on crystalmark, and compared it to my friend's identical hard drive, which shows that mine is clearly not running optimally. My harddrive has been defragged multiple times.

Specs:
Cpu: i5-6600k
Gpu: GTX 1060
Motherboard: Gigabyte Z170 HD3-P
Psu: EVGA 650w
SSD: Kingston 120GB
HDD: Seagate ST1000DM003

first let's verify windows caching is working.
Disk Management, right-click a drive-->Properties-->Hardware-->highlight a drive-->click Properties ... you will see a policy tab - click that. Now you have a screen that shows windows caching. You want the top one ON - "enable write caching" and the bottom one OFF "disable write cache buffer flushing"

You've already made sure the drive is being defragged correctly. For someone else reading this thread: right click disk drive, properties, tools, optimize - check the date of last defrag.

If there is a hardware problem its with the MB sata slot or the drive itself. The sata link trains up to a speed that doesn't give errors. 99% of the time in a PC this is full speed, but it can be slower. This might show up as a "downshift" in the smart data output, or that might only report cases when the link speed was initially negotiated down below the max the drive supported. I'd open case and reseat the sata cable on both ends, and see if there is a different sata port avail on the MB. maybe a different cable.

Speedfan, a program used to control fan speeds, used to be able to send smart and performance data to a central site and come back with a rating on your drive vs. other people's results using exactly the same drive. It worked well years ago, but when i tried it today the site that did the analysis was dead. Here is what it used to look like, not sure if it is jsut down for the day, or if it hasn't worked for years: http://www.ghacks.net/2008/08/07/analyzing-drive-health-with-speedfan/ You've already done that with your friends identical drive.

Is your drive still under warranty? I'd guess so from the PC build date. Might be time to open an incident with seagate and see what they will do.
