We have produced a Whitepaper covering Solid State Drives, why they fail, how they fail and what some of the recovery options are.
Generally speaking Solid State Drives are more robust than traditional hard drives. However, robustness does not always equal reliability. Bianca Schroeder from the University of Toronto, Raghav Lagisetty and Arif Mechant, Google Inc. presented their research at the 14th USENIX Conference on File and Storage Technologies (FAST’16). The study has shown that while Solid State Drives have experienced a significantly lower replacement rates than mechanical hard drives, they also have experienced higher rates of uncorrectable errors. Their research has furthermore shown that between 20–63% of Solid State Drives experience at least one uncorrectable error during their first four years in use.
Therefore, while switching from hard drives to Solid State Drives does seem to provide certain benefits, it in reality would be faulty to assume that this will guarantee a mitigated failure or data loss rate.
There are several type of failures that can affect Solid State Drives. The Whitepaper will cover the most common failure types, together with the challenges and the recovery solutions if data needs to be salvaged from a damaged SSD.
