Incorporates new TDK GBDriver GS1 controller for high reliability SATA Gen. 3 SSDs

  • Integrated power supply protection circuit
  • Support for SLC, MLC, pSLC flash memory

TDK Corporation announces the new CAS1B series of 6 Gbps serial ATA compatible CFast type solid state drives for industrial applications, featuring the NAND flash memory controller chip GBDriver GS1. The new products will be available from January 2016.

Recently, the use of highly reliable and robust card type storage devices with high capacity is increasing in industrial applications, as operating systems tend to have higher overheads and ease of handling is also an important factor. In response to such demands, TDK has developed a new series of CFast cards, which boast 3.2 times faster read and 1.9 faster write speed than the existing CAG3B series, while maintaining the excellent reliability that we are renowned for.

Industrial applications also increasingly call for solid state drives with MLC NAND type memory. In such cases, improved data retention capability as well as high reliability becomes important considerations along with the regular benchmark test results. To meet such requirements, the new controller not only features the recovery and refresh functions implemented by the existing GBDriver series of controllers, but also comes standard with a highly acclaimed power interruption tolerance algorithm as well as an integrated power supply protection circuit. This assures highly robust data reliability both with SLC and with MLC NAND type flash memory.

The standard lineup also provides the choice of pSLC flash memory, which offers higher robustness than MLC and lower cost per bit than SLC, resulting in a good balance of reliability and cost.

Data security has also been enhanced. In addition to the standard ATA security complement, AES*1 128-bit and 256-bit encryption and a TDK proprietary security function are also available. This makes it possible to store data in the NAND type flash memory in encrypted form, to guard against the risk of data leaks and tampering, resulting in highly robust storage security.

The new CAS1B series will be exhibited at the “Embedded Technology 2015” and “IoT Technology 2015” to be held at the Pacifico Yokohama from November 18 to 20 this year.
