Both drives are nvme as W1zzard noted; perhaps the native nvme driver is being used which forces FUA? If .NET framework is used during Office installation with Force Unit Access enabled, the queued performance rates can drop wildly. Try running AS SSD (.NET base) on a NVMe drive with the native Win10 nvme driver. Yikes.

I just double checked. By default the "Enable write caching on the device" checkbox is checked on the Samsung 950 Pro.

Also I ran an additional test with "Turn off Windows write-cache buffer flushing on the device". No difference. Office still over 3 minutes.

That won't make a difference on the Samsung. You need to actually load Samsungs NVMe driver, which forces FUA off.
