Slow downs in SATA transfer speed
I am having an odd issue where the transfer speed from my HDDs slows to unusable after my computer has been on for a while.
I have my primary OS drive as a Samsung 850 1TB SSD, paired with 2 x 3TB Toshiba HDDs. When I first start my computer, everything works as it should. After a few hours however, the transfer speed from the 3TB drives slows to around 200kb/s (according to resource monitor). At this speed the drives are almost unuseable. I am not quite sure where to begin diagnosing this problem. I am using an Asus Maximums VIII Hero Alpha motherboard with Core i5 6600K Skylake processor, and 16GB. As far as I can tell the problem is limited to the HDDs, not the SSD. Looking at resource monitor, there is nothing lse using the drive that would explain the transfer speed, and there are no processes overusing the CPU. There are no programs installed on the HDDs, they are used for storage only. One stores my docs, music and video files, the other contains backups of the other drive created by EaseUS. I use Intel Rapid Storage Technology drivers.
If any other information would be useful, please ask. Any assistance would be appreciated.
