TDK Corp. has introduced the CAS1B series of 6Gb/s serial ATA compatible CFast type solid state drives (SSDs) for industrial applications. Featuring the NAND flash memory controller chip GBDriver GS1, the devices boast 3.2 times faster read and 1.9 faster write speed than the existing CAG3B series, while maintaining the excellent reliability, stated the company.

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.

Industrial applications also increasingly call for SSDs 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 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, noted the company. 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 128bit and 256bit 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.

Some applications of the SSDs include factory automation equipment; railway and transport equipment; cashless registers and other point-of-sales (POS) equipment; office equipment; base station equipment for 4G/LTE systems; smart grid equipment; and security and surveillance equipment.

The new products will be available from January 2016
