Hi [NAME] welcome to this free user-to-user Alienware laptop discussion forum.  Please install Alienware m15 NVMe drive within your other PC spare PCIe slot to see if this drive is one half of RAID or a singleton drive. 
last weekend my faithful alienware m15 died.  it was running when I went to bed and was dead in the morning.  I attempted to resuscitate it by discharging the battery and trying to restart, but no luck.  The power cable jack illuminated, but the laptop itself was dead with no lights of any kind.  I brought it into the local Best Buy and they confirmed my speculation that it was probably not the battery, but the motherboard and it would be costly to diagnose and repair it.  So I resigned myself to recovering the data from the hard drive and moving on to a new laptop.  Which brings me to my question... When I went to remove the harddrive, I discovered that there isn't one!  It has two nvme ssds.  My hope was that I'd be able to simply mount the hard drive to my desktop pc to recover data, but the dual nvme setup presents a little challenge.  I'm not sure whether these were raid configured, in which case I suspect I would need to find a dual port nvme enclosure that supports an intel raid configuration?  I haven't been able to find such a thing. Is there a way I can confirm whether these were set up as a raid array?  If they weren't, that would be great!  I could just get an nvme enclosure and copy the data off each drive that way.  I -think- there was only one hard drive on my laptop (it was a secondary computer that I only used periodically and I can't be sure.), which suggests to me they were probably set up in a raid array.  At any rate... if there's any advice to be had for recovering data off these alienware m15 nvme ssds, I would certainly appreciate it!
