1.2.9. Endurance
The IDE 4000 provides 2,000,000 write/erase cycles and an unlimited number of read cycles.
Performance is enhanced by the following features:
• Wear-Leveling Algorithm: This algorithm guarantees the use of all flash components at the
same level of the write/erase cycle.
• EDC/ECC (Error Detection Code/Error Correction): The enhanced Reed-Solomon
EDC/ECC extends disk endurance by detecting and then fixing flash blocks.
1.2.10. Mean Time Between Failures (MTBF)
Table 6 summarizes the MTBF prediction results for various IDE 4000 configurations. The
analysis was performed using a RAM Commander™ failure rate prediction.
