New build with a GA-Z170X-Designare, I bought an Intel 750 (U.2) plus four 850 EVO's.
One of four shows as not in AHCI mode.
Exercising them while waiting for a replacement MB (a whole different story), noticing one benchmarked slightly different (say about 8%) than the others, I downloaded Samsung Magician and looked at it. It says it is not in AHCI mode (it is).
The other three are fine; I've cycled them through in turn. On same port and cable three always say AHCI, one does not.
I've read lots of threads about Anniversary update and AHCI, as well as numerous ones about whether one is really using AHCI setup, drivers, etc. This seems different, in that it is specific to one drive (not port, drive). To those, I am not in secure boot mode, and it is set to SATA/AHCI in bios; both working and non-working drives show driver "disk.sys", "EhStorClass.sys" and "patmgr" under the device manager, driver, details.
All four drives verify in Magician as "genuine". All four drives function, more or less normally. The suspect drive runs a bit slower, maybe 1-3% on most stuff, about 9% on 4K CrystalDiskMark. That's not significant to me and is not my concern per se, only that it is a possible symptom as it is quite consistent between it and the other 3.
All four have the same firmware.
This is a new build, now is the simplest time to replace it if it may indicate a hardware issue....
Any ideas? Any steps you would take to ensure this is not a symptom of a pending problem?

PS. These are specifically MZ-75E2T0B/AM drives, 2TB, all from Amazon; I don't know how to get a manufacture date or anything, but power on hours in S.M.A.R.T. shows they were all at least approximately new.
