If they were my drives, I'd be performing a post mortem examination.http://www.notebookcheck.com/uploads/pics/chips_seite1_adata_s510.jpghttp://ssd.thessdreview.com/wp-content/uploads/2011/11/PCBFrontC.jpg
On the rear of the PCB are several (3 or 4) switchmode power supplies. I would measure their output voltages. I could help you with this if you know how to use a multimeter.
There also appears to be a protection (?) device near the +5V pins at the SATA power connector.
AFAICT, your board does not appear to have any backup capacitors, so your SSD's design may be vulnerable to corruption from power interruptions.
