4.2. Reliability
The SSD provides a very high number of hours for Mean Time Between Failures (MTBF). Exact
times are density dependent, as described in Table 12.
Performance assessments are based on Telcordia SR-332, GB, 25°C. A detailed MTBF report
can be provided upon customer request.
Note: The information in this section is relevant for SSD units with firmware version 1.07 and
4.3. Embedded Error Detection and Error Correction Code
The SSD has embedded error detection and error correction hardware and software mechanisms.
The EDC/ECC uses the BCH algorithm, which can detect up to 5 errors in 512 bytes of data, and
correct up to 4 errors.
