Data Integrity

High Performance

The 2nd Generation ASIC controller of DERA D6436/ D6456 NVMe SSD is developed by DERA with software-hardware co-designed methodology, achieved enterprise-class data integrity, many built-in hardware acceleration units, sophisticated NAND flash management, and performance aggregation in a power-efficient way. Architected with advanced YMTC 128-layer 3D TLC NAND, D6436/ D6456 deliver reliable and high performance NVMe storage solution. D6436/ D6456 offer endurance and capacity options of 3.84TB, 7.68TB at 1 DWPD (5yrs), and 3.2TB, 6.4TB at 3 DWPD (5yrs).

DERA D6436/ D6456 NVMe SSD realized intense hardware LDPC units, end-to-end protection on the whole data paths against silent errors, adaptive redundancy protection among independent NAND units, and protection against unexpected power-losses, which are forged into an integrated protection for user data. In addition, D6436/ D6456 NVMe SSD constantly sense drive's healthy and react in time accordingly, which is available for host management software to perceive and handle potential drive failure.

DERA D6436/ D6456 NVMe SSD achieved high performance with low latency. Sustained random write IOPS up to 400K, random read/ write latency low to 79/ 11us. Optimized FTL algorithm sufficiently anticipate the extreme conditions of highly-intense workloads and workload variations with sophisticated scheduling and controls over front-end I/O demands and FTL backend activities, ensuring a stable performance in all cases. D6436/ D6456 NVMe SSD deliver a performance consistency above 90% in significantly heavy random I/O workloads.
