I just updated to Windows 10 and tried moving the Windows.old folder the update created on my SSD to my larger HDD, but the transfer speeds I'm getting are painful. In total, the folder is 169gb and is currently writing at less than 500 kb/s (currently estimated to take more than 1 day). I realize there are lots of small files to write and hence a lot of overhead, but this seems a little ridiculous.

I updated my chipset drivers and AHCI is enabled. Is there any reason for the transfer to be going this slowly?

Hey there, djl62490.

You should make sure that the cables are properly connected. You could also try the drives with different SATA ports and cables, or with a different computer, to see if the issue still persists.
I'd also advise you to download a diagnostic tool (preferably each drive manufacturer's diagnostic tool) to check just the SMART data and see if there's anything unusual. Don't run any tests yet as this might be damaging to your data if one of your drives is having issues.
Another thing you could try is to transfer the same file to an external drive both from the HDD and from the SSD to see which one of them will give you the unusually low speed.

Hope that helps. Please let me know how everything goes.
