RAID F1
Compared with traditional RAID, RAID F1 distributes uneven workload to SSDs to prevent all drives from wearing out simultaneously.

Flash volume deduplication

Leverage volume-wide deduplication to remove duplicate data on all-flash arrays and greatly increase storage efficiency. Eliminate redundant data to save up to 65% of storage space use in applications like virtual desktop infrastructure and virtual machines.2
