Toshiba Introduces First Enterprise-Class SSDs With 64-Layer 3D Flash Memory
Toshiba America Electronic Components, Inc. (TAEC), a committed technology leader, today unveiled the development of two new flagship enterprise solid state drive (SSD) solutions, the TMC PM5 12Gbit/s SAS series and the CM5 NVM Express® (NVMe™) series. Development is expected to be completed in the fourth quarter. Both product lines are built with TMC’s latest 64 layer, 3-bit-per-cell enterprise-class TLC (triple-level cell) BiCS FLASH, making it possible for today’s demanding storage environments to expand the use of flash with cost-optimized 3D flash memory. With all-new, advanced features, the innovative CM5 and PM5 series raise the bar in performance capabilities and create new opportunities for businesses to leverage the power of flash storage.

Offering up to 30.72TB in a 2.5-inch form factor, the TMC PM5 series introduces a full range of endurance and capacity SAS SSDs enabling data centers to effectively address big data demands while streamlining storage deployments. With the industry’s first MultiLink SAS™ architecture, the PM5 series is able to deliver the fastest performance the market has seen from a SAS-based SSD with up to 3,350 MB/s of sequential read and 2,720 MB/s of sequential write in MultiLink mode and up to 400,000 random read IOPS in narrow or MultiLink mode. The PM5 series’ 4-port MultiLink design is an additional technology to achieve high performance, close to PCI EXPRESS® (PCIe®) SSDs, enabling legacy infrastructures to increase productivity without having to be re-architected from the ground up. Furthermore, PM5 SSDs support multi-stream write technology, a feature that intelligently manages and groups data types to minimize write amplification and minimize garbage collection, translating into reduced latency, improved endurance, increased performance and Quality of Service (QoS).

Western Digital Corp. today announced its successful development of four bits per cell, X4, flash memory architecture offering on 64-layer 3D NAND, BiCS3, technology. Building on its pioneering innovation of X4 for 2D NAND technology and past success in commercializing it, the company has now developed X4 for 3D NAND by leveraging its deep vertical integration capabilities. These include silicon wafer processing, device engineering to provide sixteen distinct data levels in every storage node, and system expertise for overall flash management. BiCS3 X4 technology delivers an industry-leading storage capacity of 768 gigabits on a single chip, a 50 percent increase from the prior 512 gigabit chip that was enabled with the three bits per cell (X3) architecture. Western Digital will showcase removable products and solid-state drives built with BiCS3 X4 and systems capabilities in August at the Flash Memory Summit in Santa Clara, California.
