[15] Enhanced Power Loss Imminent – Designed-in firmware check to validate data is saved accurately upon power restoration. Unclear if others provide this additional firmware check. Robust End-to-End Data Protection – Built-in redundancy where both ECC and CRC can be active at the same time. Protecting all critical storage arrays within the controller – instruction cache, data cache, indirection buffers and phy buffers. ECC coverage of SRAM to over 99% of array is among the highest in the industry.
[16] Solidigm drives are tested at the neutron source at Los Alamos National Labs to measure Silent Data Corruption susceptibility to 1E-23 and modeled to 1E-25. Test prefills drives with a certain data pattern. Next, the neutron beam is focused on the center of the drive controller while IO commands are continuously issued and checked for accuracy. If the drive fails and hangs/bricks, the test script powers down the drives and the neutron beam. The drive is subsequently rebooted, and data integrity is checked to analyze the cause of failure. SDC can be observed during run time causing a power down command or after reboot if the neutron beam has hit the control logic hanging the drive as a result of inflight data corruption. Because drives go into a disable logical (brick) state when they cannot guarantee data integrity, brick AFR is used as the measure of error handling effectiveness. Solidigm drives have used this testing procedure across 4 generations. Cumulative testing time across generations is the equivalent of over 6M years of operational life in which zero SDC errors have been detected. The most recent testing used the Solidigm D5-P5520 drives which served as a proxy for the Solidigm D5-P5430 drives since they share the same controller and similar firmware. Competitor drives tested were the Samsung 983 ZET, Samsung PM9A3, Samsung PM1733, Micron 7400, Micron 7450, Kioxia XD6, Toshiba XD5 and, WD SN840.
[17] Uncorrectable Bit Error Rate (UBER) - tested to 10X higher than JEDEC specification. Solidigm drives are tested to 1E-17 under full range of conditions and cycle counts throughout the life of the drive which is 10X higher than 1E-16 specified in JEDEC – Solid State Drive Requirements and Endurance Test Method (JESD218). https://www.jedec.org/standards-documents/focus/flash/solid-state-drives. Silent Data Corruption (SDC) - modeled to 1E-25. Typical Reliability Demonstration Test involves 1K drives for 1K hours to model levels down to 1E-18. Solidigm drives are tested at the neutron source at Los Alamos National Labs to measure SDC susceptibility to 1E-23 with modeling to 1E-25.
