Title: ARRANGING SSD RESOURCES BASED ON ESTIMATED ENDURANCE
Abstract:
A technique for managing SSDs in a data storage system generates an endurance value for each of multiple SSDs and arranges the SSDs in RAID groups based at least in part on the generated endurance values. As a result of such arranging, some RAID groups may include only SSDs with higher endurance values while other RAID groups may include only SSDs with lower endurance values. The data storage system may then run RAID groups with higher endurance values at higher speeds and may run RAID groups with lower endurance values at lower speeds.
