Are you sure that something else is not responsible for the increase in the 4K read benchmark result? That same difference from 40MB/s to 60MB/s can be accomplished by using the Windows High Performance Power Plan, or configuring the Minimum processor state entry in the power plan advanced option, and disabling all the CPU power saving options in the UEFI/BIOS. So it does not make sense that an AHCI driver should affect the performance of an NVMe SSD. The NVMe controller chip is part of the 960 EVO itself, while the SATA controller is part of the system's chipset, whether external like Intel's and older AMD platforms, or part of the Ryzen SOC, and some Intel SOC type processors. NVMe and SATA are two different, non-interchangeable protocols. You'll find an entry in Device Manager under Storage Controllers for the NVMe controller, showing the NVMe driver that is installed.

It uses either the Microsoft NVMe driver, or Samsung's NVMe driver. The Samsung 960 EVO, being an NVMe SSD, does not use the SATA AHCI driver. Default Microsoft I get 40 MB/s read for 4K with my Samsung 960 EVO but now it's at 60 MB/s read. They only have it for Windows 8 / Windows 7 but my 4K scores went up slightly after using the AMD. In the AMD chipset all in one package, I installed the AHCI drivers (updated in device manager over Microsoft 2006 ones). That sounds like typical excuses from Samsung about problems with the Magician software. Of course, AMD has multiple AHCI drivers for at least three different chipset now. In the past, the Magician software did not support the AMD AHCI driver until recently. It has been used since Windows 8, and seems to simply be a rename of the older msahci AHCI driver. I'm surprised the Magician software is not recommending the Microsoft storahci AHCI driver. The Windows 10 storahci driver will be installed during the installation, but you should be able to manually update it in Device Manager. Might that be poor 4K random read and write speed performance on SSDs? You seem to be looking for a Windows 10 AM4 AHCI driver for a particular reason. I am using RAID mode on my X370 board, so cannot tell you what AHCI driver I have installed, since I obviously have the RAID driver installed. It may be difficult finding the AHCI driver among all the files in this download. You have said the 17.10 'chipset driver' but have you checked or used the AMD 'All in One' driver package? It's the same version provided with any ASRock AM4 board, so this link is just to the AM4 board I have:
