Of-the-shelf SSDs are optimized for speed and price.
Flight recorders are typically specified to withstand an impact of 3400 g and temperatures of over 1,000 °C (1,830 °F), exposure to salt water, and high pressure if it sinks to the bottom of the sea as required by EUROCAE ED-112.
Maybe you could design a flight recorder that uses SSDs, but then you must get it certified again for the new hardware, which will cost a lot of money nobody wants to spend.
The next step in flight recorders is to also send a live feed of telemetric data back to some ground station so the last position of the plane is known - with a flight recorder you only get this data after you found the wreck. Currently submitting this signal is optional and can be turned of by the pilot, which is the reason why Malaysia Airlines Flight 370 is still missing.

Maybe? Really?
I think this is probably more of the answer. Capitalism 101.
