Hey guys, idk whats going on, but a new install of win10 pro x64 has EXTREMELY slow read/write times on my HGST 3TB drive.

This has only started happening since I reinstalled windows. What is the world is going on?
*nix does NOT have this issue.

Trying to zip the attached report while transferring these files resulted in the zip not being created until I paused the transfer.

UEFI or not won't make any difference. One thing looking at the picture is that you are copying a large number of presumably smaller files. That alone is going to have a huge impact on performance. I'd wager if you copied a single large file you'd get a much higher throughtput on the write. Sequential writes are much faster than random writes.
Try lowering your FSB back to 200 as fsb overclocks can affect the southbridge and storage controllers.
 
I don't think I changed anything , i'll 'optimize" defaults and put it on turbo in bios ( asus settings ) should that do it?
oh, an could uefi have anything to do with it? I don't think it was using that before this last reinstall
 
ok, reset to optimized changed one setting to D.O.C.P. but couldn't find anything related to FSB. I left it on normal not turbo though.

whats strange is I didn't have this problem until I reinstalled win10.
Does UEFI vs non make a difference?
Does it matter which sata port is used?

ok, but my question goes back to why did I not experience this issue before?
The difference in performance between windows and linux is like a 1930's vw and 2017 Ferrari
 
Windows and Linux write to disk very differently. Windows will cram files together while Linux writes everything spaced much further apart. This is also why Windows has a high degree of fragmentation and Linux doesn't. That fragmentation will further exacerbate the write issue.
