m15 R3, RAID 0 DATA Recovery

I have a Dell Alienware M15 R3 laptop purchased a few years ago. It had been functioning well, until a few days ago when I was watching some videos, I saw a flash/spark inside the laptop and the screen turned black and I heard noise in the earbuds. I thought something might burned and I shut down the machine immediately. After a few minutes I tried to restart the laptop, and it wouldn't turn on. The power button flashes in an unusual pattern indicating error, and the screen remains black, and I couldn't not hear the sound from the fan. 

Since I was planning to switch laptop anyway, my roommate suggested me to remove the SSDs from the board and copy the data to another computer (we share this laptop together). And here comes the problems. I have three SSDs in the laptop, one smaller one (Nvme 2230) and two larger ones (both Nvme 2280).  I put the smaller one into an enclosure with USB cord and successfully copied the data to another device. But when I tried to do the larger ones, they cannot be recognized. I then checked the laptop information carefully and found that those two larger SSDs are actually under RAID structure, probably RAID0. My roommate then used some data recovery softwares to attempt to recover data from one of the SSDs, but the recovered files are most corrupted and cannot be opened, and I guess we must read the two SSDs together to get the intact files. 

I wonder if in this case there is still chance to save the data from my SSDs. There are some important data on it and some confidential information too. These data are so important they are actually 4 years of work in graduate school. If I knew that RAID0 is so dangerous I would never choose product using that. If I repair the mother board or replace the old mother board, and then plug the SSDs back in, would they still work? The worst part is we cannot determine the order of those two SSDs now since they all look the same, does that matter?

Thank you so much for help!
