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.
