3D NAND is well on its way to become the main NAND player in the flash memory market. This next-generation NAND flash promises greater capacities and performance and is now available in a fully industrial-grade package. The Innodisk solid state drive (SSD) series is designed to tackle the tough conditions seen in many embedded environments and to handle the challenges of edge computing.

The Innodisk range uses pure industrial-grade 3D TLC NAND from Toshiba, with  3000 P/E cycles which ensures lasting endurance as required by many embedded applications. The firmware is also optimized for industrial use and the SSDs avoids SLC caching to evade performance drops and increase write amplification that lower P/E cycle numbers through excessive data transfers within the SSD.

The series includes two models: 3TE7 and 3TG6-P, with the former being DRAM-less and the latter uses an external DRAM chip and a Marvell controller. The modules can incorporate AES encryption for data security and End-to-End Data Path Protection to ensure error correction at every point of data transfer. The modules can also be fitted with Innodisk’s trio of power stabilizing technologies iCell™, iPower Guard™ and iData Guard™ to further strengthen data integrity in areas susceptible to power fluctuations.

Both ranges work in Direct TLC mode. Direct mode is able to provide stable and linear performance without sudden performance drop as well as reduce the WAF. So throughput might be slower the performance is consistent with no drop off after a few minutes of operation –  a key feature for heavy workloads.

Supply longevity

3D NAND is relatively new to the industrial sector so will naturally evolve. Established 2D NAND such as SLC and MLC which is still in high demand, will not be replaced by 3D NAND anytime soon with SLC and MLC supply guaranteed until 2023.
