Toshiba Introduces TR200 SSD Series With 64-Layer 3D Flash Memory
Toshiba America Electronic Components, Inc. (TAEC), a committed technology leader, today unveiled the TR200 SATA solid state drive (SSD) series for the retail market. Leveraging Toshiba’s latest 3-bit-per-cell TLC (triple-level cell) BiCS FLASH, the TR200 series offers PC gamers and DIY enthusiasts Toshiba’s first upgrade SSD with 64-layer 3D flash memory.

Toshiba TR200 SSDs are an easy and affordable way to enhance notebook or desktop experiences by increasing system responsiveness and productivity over traditional hard disk drives (HDDs). With a 6Gbit/s SATA interface, the TR200 series is rated for sequential read/write speeds of up to 550MB/s and 525MB/s and random read/write performances of up to 80,000 and 87,000 input/output operations per second (IOPS). In addition to excellent SATA performance, TR200 SSDs provide low power consumption that translates into a longer battery life for on-the-go users.

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.
