NUC7i5BNH upgraded to BIOS 72 and all of a sudden my M2 EVO 970 PRO SSD started backing up at 126MB per second down from about 440MB.Same with Samsung Magician test.

Reinstalled BIOS 71 and now back to almost the same performance.

Win10PRO Insider build 18305

 Updated using .bio F7 method.

So all is OK now.

Reinstall this BIOS 72, but this time do so via the jumper-based BIOS Recovery method (which is documented here: http://www.intel.com/content/www/us/en/support/boards-and-kits/000005532.html?wapkw=bios+recovery).

 

It has been suggested that removing the SSD while performing the update may be more effective than leaving it in. This is being investigated. In the meantime, I would suggest that you do so.

 

Hope this helps,

I have used F7 without issue since I got my NUCabout 6 months ago. The only thing changed is that I upgraded windows from Home to Pro. I might re-download and do another test with F7 and if I get a problem again I'll go back to 71 it works fine.

Ironically 72 is supposed to have M2 fixes in it not introduce M2 problems.
