RAID 1 Array: SATA vs PCIe controller

[BobSmith]

I originally had 2xSATA SSDs setup in a RAID 1 array. I recently replaced both drives with PCIe NVMe SSDs. I was able to do the migration just fine by removing and rebuilding one drive at a time. My question is, the RAID 1 array was originally setup using the SATA controller option in "Create RAID Volume". Now that I have NVMe drives, should I break the RAID 1 array and recreate it using the PCIe controller option in "Create RAID Volume"? Are there any performance benefits of SATA vs PCIe controller?

Thank you.

I also have the same problem on an MSI Pro b760 MP motherboard where it is not possible to configure Raid 1 with PCI Express disks.
