Hi [NAME]  Support for Alienware m15 Ryzen Edition R5, Internal slots says only M.2 solid-state drives can be installed and PCIe Gen3 x4 NVMe is reiterated in Storage.   PCIe slots can accept M.2 SATA and NVMe SSD cards. M.2 SATA SSD is not detected in Alienware 15 R4 and Alienware 17 R5 | Dell US However, the m15 R5 documentation makes no mention of M.2 SATA SSD cards being accepted by the motherboard. Have a look beneath the M.2 cards to see it there is any text that shows what will be recognised.  I have installed M.2 SATA SSD in my 17 R5 in PCIe slot that does not accept it and there was no damage, so presume seeing if M.2 SATA SSD can be accepted in m15 R5 PCIe slot will not damage anything.

The NVME slots on some systems can be configured to be backwards compatible with SATA drives. Sometimes this is automatic, sometimes configured in the BIOS. Is this possible to do this with an m15 R5? I ask because I have an extra 2TB m.2 SATA and it would be nice to use it as a 2nd drive (it will be a data drive where speed isn't nearly as important). P.S. I know that NVME never works in a SATA slot -- the pins are even configured to block an accidental insertion. But NVME is intentionally configured so that you can insert a SATA SSD -- it just needs to be supported by the board to work. Thanks in advance!
m15 R5, M.2, is it possible to use a SATA drive instead of PCIe NVME?
