IRVINE, Calif.--()--Toshiba Storage Products, Business Unit of Toshiba America Electronic Components, Inc., a committed technology leader, today announced a new lineup of solid state drives (SSDs) that provides both high performance and energy efficiency for the most data-intensive and energy-sensitive applications. The THNSNF drives are the world’s first to take advantage of 19nm process NAND flash memory, which delivers major advances in power consumption and performance. Continuing Toshiba’s long history of innovation in NAND flash memory — 2012 marks the 25th anniversary of Toshiba’s invention of NAND flash — the THNSNF series provides an ideal storage solution for high-end and thin and light notebooks, all-in-one desktop computers, embedded systems and external storage devices for consumer and industrial PCs.

The THNSNF series employs Toggle MLC (multi-level cell) NAND flash, which delivers significantly faster performance than competing SSDs using synchronous or asynchronous NAND flash. Clocking in at around twice the speed of Toshiba’s HG3 series SSDs, the THNSNF series will be available in four capacities (64, 128, 256, and 512 GB) and in three form factors:

  • THNSNFxxxGBSS - 9.5 mm height, SATA 6Gb/s
  • THNSNFxxxGCSS -7.0 mm height, SATA 6Gb/s

Toshiba’s unique integrated SSD design and manufacturing capability ensures that key components of the SSD, from firmware to controllers, as well as NAND flash, are designed by Toshiba, further underscoring Toshiba’s vertical integration and leadership strengths in the growing SSD market. Toshiba’s innovation with the THNSNF series includes data protection through use of Quadruple Swing-By Code (QSBCTM), Toshiba’s robust and highly efficient error correction code technology.

The THNSNF series delivers efficient power utilization of less than 0.1 W, exceeding the Business Applications Performance Corporation MobileMark® 2007 benchmark for battery life, a critical standard for next-generation ultrathin notebook PCs as well as current notebook PCs. The THNSNF series employs Advanced Power Management (APM) technology to control power consumption, and offers optional Automatic Thermal Control to reduce power consumption in response to drive temperatures.

“Our customers are increasingly looking to SSDs as a storage solution across multiple products and markets because of the performance and reliability they deliver,” said Joel Hagberg, vice president of marketing at Toshiba’s Storage Products Business Unit. “The THNSNF series provides not only great performance, but also extremely low power consumption across a broad range of form factors and capacities. These are critical features for our customers as they design the next generation of PCs and embedded systems.”

Mass production for the THNSNF series will begin in August 2012.

1. One Gigabyte (1GB) means 109 = 1,000,000,000 bytes using powers of 10. A computer operating system, however, reports storage capacity using powers of 2 for the definition of 1GB = 230 = 1,073,741,824 bytes and therefore shows less storage capacity. Available storage capacity (including examples of various media files) will vary based on file size, formatting, settings, software and operating system, such as Microsoft Operating System and/or pre-installed software applications, or media content. Actual formatted capacity may vary.

2. Toshiba Semiconductor & Storage Products Company defines “RoHS Directive” as the Directive 2002/95/EC of the European Parliament and of the Council of 27 January 2003 on the restriction of the use of certain hazardous substances in electrical and electronic equipment.

3. Toshiba Semiconductor & Storage Products Company defines Halogen-Free/Antimony-Free solid state drive (SSD) or hard disk drive (HDD) products as those meeting all of the following requirements:

(a) containing bromine (Br) and chlorine (Cl) in no more than 900 parts per million (ppm) by weight for each element, and containing bromine and chlorine in an aggregate amount not exceeding 1500 ppm by weight; and (b) containing no more than 1000 ppm antimony (Sb) by weight.
