New ATA-compatible 2.5-inch solid-state drives target industrial applications

08-05-2015 | TDK | Subs & Systems

TDK's new SDS1B series of 6Gbps serial ATA-compatible 2.5-inch solid-state
drives for industrial applications, feature the NAND flash memory controller
chip GBDriver GS1.

Recently, the need for fast, high-volume data storage is on the rise, driven
by developments such as larger operating system overheads and the trend
towards high-definition large-capacity data applications as exemplified by
4K and 8K full high-resolution data broadcasting. As data volumes increase,
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 become 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.

Without incorporating a DRAM or other type of cache, the new product
achieves read access speeds up to 440 MByte/second and write access speeds
up to 220 MByte/second*1. The results are SSD products with significantly
improved access speeds, reflecting TDK's extensive experience and in-depth
knowledge of the realities of industrial applications.

Data security has also been enhanced. In addition to the standard ATA
security complement, AES*2 128-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, says the company.
