Case summary
The SSD became increasingly slow, then stopped allowing file access.
The failed SATA SSD required a controlled recovery plan. Unlike many hard drives, modern SSDs combine controller behavior, firmware, NAND condition, encryption, and tool support into one tightly connected recovery problem.
Device
Samsung 850 PRO 128GB SATA SSD.
Failure
Long-term slow operation followed by sudden loss of access.
Main challenge
Internal encryption and controller dependence limited direct NAND options.
Recovery path
Board access, professional diagnostics, stabilization, and controlled extraction.
What made it difficult
Removing NAND chips does not automatically produce usable files.
Controller-managed translation and encryption meant the original SSD electronics remained important to recovery. The case required a path matched to the controller and failure state rather than a generic software scan.
Outcome
The accessible data was recovered and verified.
Careful diagnosis preserved the available recovery path and allowed the recovered files to be validated before return.
