Abstract EN
Solid-state drive (SSD) becomes popular as the main storage device.
However, over time, the reliability of SSD degrades due to bit errors, which poses a serious issue.
The periodic remapping (PR) has been suggested to overcome the issue, but it still has a critical weakness as PR increases lifetime loss.
Therefore, we propose the conditional remapping invocation method (CRIM) to sustain reliability without lifetime loss.
CRIM uses a probability-based threshold to determine the condition of invoking remapping operation.
We evaluate the effectiveness of CRIM using the real workload trace data.
In our experiments, we show that CRIM can extend a lifetime of SSD more than PR by up to 12.6% to 17.9% of 5-year warranty time.
In addition, we show that CRIM can reduce the bit error probability of SSD by up to 73 times in terms of typical bit error rate in comparison with PR.
