Ok, everything is working fine on the new drive. Here’s what I did, for anyone else going down this path: Cloning:1. Put one new blank M2 NVMe drive in a USB enclosure and plugged it in to the laptop.2. Cloned the existing RAID volume (all partitions) to the new drive using Macrium Reflect 8 Free (not Trial), as per here: [URL] (note that you have an option in Reflect 8 to expand to fit, which automatically expanded my Windows partition to fit the extra space on the larger drive…I didn’t need to do the complicated manual partition sizing shown in many youtube tutorials based in older versions of Reflect).3. Removed the old M2 drives and installed the new one per here: slot 1: [URL] and slot 2 [URL] .4. Optional: I had a second new drive too, so initialized and quick formatted the new non-boot drive in the second slot. Removed RAID as in this video, super easy: [URL] Here’s the steps for that:5.. Booted up computer using new drive, then ran cmd as administrator, typed in at prompt without quotes “bcdedit/set safeboot minimal” . You should get confirmation “operation was completed successfully”. 6. Restart computer 7. Spam F12 during startup to go into BIOS, select BIOS Settings > System Configuration > SATA Operation and change from RAID On to AHCI, confirm. 8. Esc to exit and boot into Windows safe mode. Run cmd as administrator again. Type “bcdedit/deletevalue safeboot” . Should get same confirmation message. 9. Restart computer, should boot into regular Windows.  10. Worked fine on generic Intel drivers, but I then downloaded the latest driver installer from the drive manufacturer’s website (Samsung in my case) and also their drive monitor and diagnostic tool (Samsung Magician). Ran driver installer and restarted computer. Working great now, no problems.
I have an Area-51m R1 that came with 2 x 256gb M2 SSD’s in RAID 0.   I’m out of space, and ordered 2 1TB M2s.  I’ve heard that RAID 0 doesn’t really add any performance with NVMe drives, but increases risk because if one drive fails, you lose everything.  So my intention is to clone the current RAID 0 drive to a single 1TB stick, which will be my new boot drive, and the other will be for storage.  I have purchased an external enclosure to hold the clone destination drive, and intend to use Macrium Reflect to create the clone.   This will be my first cloning of a boot drive, and could use some advice on procedure.  Unfortunately, I haven’t seen anything on the forums here that is the same scenario…what I’ve found has 2.5” SATA drives or other RAID configs involved.  Can anyone direct me to a good tutorial for my situation, or outline the steps I will need to do this? Cloning via Reflect 8 seems pretty straightforward (I’m assuming the RAID won’t matter, it will see it as just one drive with the usual partitions). I’m most concerned about making the correct changes to BIOS settings, and getting the clone to boot successfully.  I also saw that one Reflect tutorial said I needed to make a Windows recovery drive to successfully boot from the new clone the first time, but they never used it in the video or mentioned again, so I’m missing some details in the process like that.  Thank for any help!
Area-51m R1, upgrade M.2 from RAID 0 to JBOD
