Mounting a RAID-0 pair of M.2 drives from older PC

My laptop uses two M.2 drives in RAID 0 as the main drive. This was stock configuration (an Acer Predator GX-792 laptop). I reformatted and installed Ubuntu 14.04 on it (using ext3 file system) with no issues and have been running it for 6 months. I did not need to set up RAID 0 in Linux. From memory, I just pointed the installer at the single existing virtual drive mountpoint and it worked immediately. (I can't remember the full details, since it was easy. I did NOT configure any RAID options in the installer or Linux though.)
Unfortunately, months later, the laptop hardware has died from a power supply issue. I now want to access the files on that boot drive. An easy solution would be to simply swap the M.2 drives with another similar laptop, but the laptop is not a common one and finding one locally is not easy.
I do have a SATA SSD based running Linux Ubuntu 14.04 desktop system which has two M.2 slots available, so I can plug both laptop M.2 drives into it.
What's the next step to MOUNT those drives? Is RAID 0 formatting standard or does it really depend on my laptop's specific controller?
I don't want to FORMAT the drives for RAID 0... I just want to access the files that already exist on them.
I assume I'd get two (unmounted) drives showing up as something like /dev/sdb1 and /dev/sdb2 and I'd start with something like
mdadm --examine /dev/sdb1
but even after studying mdadm I'm not sure how to MOUNT them or if mdadm can mount drives that it didn't format itself [is RAID 0 striping proprietary?]
I'm asking for advice before I begin since it would be tragedy to accidentally corrupt the data using a wrong strategy.
Thanks!
