SSD Swap Slow Performace
I recently swapped out my base drive in my Latitude 7330 Rugged to a Samsung 990 Pro. Unfortunately, I am getting really poor performance in every category. I also see that Samsung Magician cannot detect my "Interface type" or "NVME Driver". On every other computer I have, these normally populate.
Steps taken:
- Update all drivers using Windows Update and Dell Command
- Attempted to change to AHCI mode (This caused an instant crash, I had to move back to RAID for it to boot)
- Install Intel RST Driver
- Reboot multiple times
- Update Samsung 990 Pro Firmware
The computer works, but the drive isn't performing where it should be. Is this just an issue with Samsung drives? Any suggestions?

To change SATA operation mode from RAID to AHCI without reinstallation of Windows, there are 2 common methods:
First method, you can make change to enable AHCI in BIOS settings and allowing the system to crash (BSOD) 2 times. On the third BSOD, Windows RE (recovery environment) will be displayed. Select Advanced Troubleshooting, select Startup Repair, then select option 4 to start Windows in Safe Mode. Once the computer start in Safe Mode, AHCI driver will be installed automatically in the background. Just select to restart system and computer will boot in normal mode with AHCI driver.
Second method, using command line:
- Click on Start button and type cmd
- Select the result Run as administrator to run elevated command
- Type or copy/paste this command: bcdedit /set {current} safeboot minimal
- Restart the computer and select F2 to enter BIOS Setup
- Change the SATA Operation mode from RAID to AHCI/NVME
- Save changes and exit Setup and Windows will automatically boot to Safe Mode.
- Run elevated command cmd again.
- Type or copy/paste this command: bcdedit /deletevalue {current} safeboot
- Reboot the computer and Windows will automatically start with AHCI drivers enabled.

@Chino de Oro I'll give it a try soon. Dell XPS 8930. Changed boot drive to 990 PRO.

If the drive is operating in Intel RST (RAID) mode, it won't be seen by Samsung Magician -- that needs the drive running in AHCI mode.
Neither will the Samsung NVMe driver load with the drive running in IRST mode.
