Crucial MX300 m2 Dead

[managerharry]

Trying to recover data off a Crucial MX300 m2 CT1050MX300SSD4 SSD. This drive was part of a RAID 0 volume with another matching MX300 drive which is OK and has been imaged. Drive does not identify itself or respond to SMART diagnostics.

Does anyone have guidance on test points to check or common failures on these models. Since I do have another matching functional drive it gives me options as far as testing and comparison.

Here are some photos

I can't see the part markings, plus there appear to be additional power components under the sticker.
