Hard drive slowing down inexplicably.

Edited because I'm pretty sure the random slowdown is from some sort of feature on wd red and green drives called intellipower, the problem is that the drive is only supposed to throttle down when it is not being used very much, so why does it decide to throttle down when I am trying to write a large amount of sequential data to it? It drops from 130 MBps read/write to about 80 MBps. That's a 40% slowdown.

Not really come across this before but you could always download crystaldiskinfo and see if there are any problems, might be worth a shot.

Sounds like a fault. I've got a green drive just for storage and it does throttle down when It's inactive but the read/write speeds are exactly what I would expect them to. You should contact western digital or move your data to another HDD and try to take it back to the store/send it back. 

 

One thing I would check out is your advanced power saving options. Check you haven't got some strange 'super power saving' options on or something. You may have it set so it even limits HDD to save power, it sounds weird but it is possible, my brother's laptop was limiting it's own DL/UL speed because he had it in power saving mode. Stupid, but it happens. This is me making the assumption that you have windows.

If you are watching the windows speed measurement, it is very unreliable... It starts off really fast and then tanks. Try a benchmarking software and then reply back.
