Actually I found that it was my add-on SATA III controller. I had added a 6 gig PCIe four port card (2 SATA and 2 eSATA) because I wanted my SSD boot drive to be fast and at least one eSATA for my drive dock. The card even had a Marvell chipset.
But after 4 hours of playing around having issues getting windows 10 to reload, I took the card out and just used the motherboard SATA connectors and moved my five 3 TB drives over the SAS ports and bam, been working like a champ ever since. Reloaded right away, no more issues with slow choppy movements or disk reads etc. Overall running much better and more like I expect Windows to run.
The one thing I did not do was make a driver disk with the chipset drivers used during OS install but it worked fine with windows 7 and 8.1 so I thought it was not needed. Since it is working great as is, the card is not going back in. Got to say even with the SATA II it still boot pretty fast is is overall faster than windows 8.1 with the same setup. WOOHOO!.
