Toshiba Memory introduces SSDs using 96-layer 3D flash memory for PC, server and embedded applications



Toshiba Memory America Inc., the U.S.-based subsidiary of Toshiba Memory Corp., introduced on Monday a new lineup of solid state drives (SSDs) that are based on its 96-layer, BiCS FLASH 3D flash memory. The initial SSD to use this technology is targeted to the client PC, high-performance mobile, embedded, and gaming segments – as well as data center environments for boot drives in servers, caching and logging, and commodity storage.

The introduction of the XG6 series paves the way for Toshiba client, data center and enterprise SSDs to migrate to 96-layer technology. Toshiba Memory is driven to continually push the boundaries of what is possible – and move the technology forward. Its 3-bit-per-cell (triple-level cell, TLC) BiCS FLASH technology improves the performance, density and efficiency of SSDs.

Its 96-layer stacking process combines with advanced circuit and manufacturing technology to achieve a capacity increase of approximately 40 percent per unit chip size over 64-layer 3D flash memory.

Speaking to the capabilities of the company’s continued enhancements to BiCS FLASH, Jeremy Werner, vice president of SSD marketing and product planning for Toshiba Memory, noted, “Toshiba Memory is at the forefront of 3D flash memory development with 96-layer BiCS FLASH. SSDs pose the most formidable flash design challenge, and becoming the first company in the world to bring an SSD to market with the most advanced flash node is an achievement that is only possible due to our years of commitment to advancing our SSD technology.”

The XG6 series is available in an M.2 2280 single-sided form factor and supports PCI Express Generation 3×4 lane and NVM Express revision 1.3a. A combination of efficiency and performance is a hallmark of the XG6 series, which consumes 4.7W or less of power and reaches up to 3,180MB/sec of sequential read and nearly 3,000MB/sec of sequential write, and up to 355,000 random read and 365,000 random write IOPS. Achieved by optimizing SoCs, the sequential write performance of the XG6 series leads the industry.

The series include Pyrite or self-encrypting drive models supporting TCG Opal Version 2.01, as well as support for block SID and digital signature;

support for user-selectable over provisioning feature through NVMe command; top-of-the-class sequential performance (client class); and enhanced SLC buffer to improve drive performance for client workloads.

“The industry continues to transition to higher densities of 3D flash technology, with 3D NAND petabytes growing at a CAGR of 75 percent out to 2022,” said Greg Wong, founder and principal analyst of Forward Insights. “The introduction of 96-layer is an important milestone for flash to meet the increasing demand for faster and denser storage.”

Ideal to a range of read-intensive applications that prioritize power efficiency, burst performance and a compact footprint, the XG6 series will be available in capacities of 256, 512 and 1,024 gigabytes. The new SSDs are currently sampling to select OEM customers.
