TDK Launches SATA II SSDs

TDK Corp. will be launching its SDG3B series of serial ATA II compatible industrial solid state drives (SSDs), with a maximum capacity of 128GB, in late September. The SDG3B drives use the TDK GBDriver RS3 series of SSD controller ICs. The drives support an effective read speed of 160MBps even though they are not equipped with cache memory.

TDK enhanced the SSDs' data reliability, a key requirement for embedded SSDs. In addition to the existing auto-recovery functions and the power interruption tolerance algorithm, the SSDs are also equipped with a powerful error-correction function scalable to 44-bit/sector error correction code (ECC) and an auto-refresh function to provide powerful tolerance against power supply problems.

In addition, TDK substantially improved the SSD lifespan. An advanced static wear leveling function and a new data randomizer function, both developed by TDK, distribute data writing among all of the flash memory blocks, maximizing the lifespan of the semiconductor storage. Also, SMART (self-monitoring and analysis reporting technology) data makes it possible to determine in real time the number of times each memory block is rewritten (erased), facilitating quantitative assessment and projection of drive life on user systems.

The drives also feature an advanced encryption function using the 128-bit AES encryption that has been registered as United States Department of Commerce Federal Information Processing Standards FIPS PUB 197. Data is automatically encrypted before writing to the flash memory, preventing data leaks and tampering. Furthermore, the drives provide a high level of storage security, preventing unauthorized copying and other data risks by using the ATA standard security functions.

The TDK SDG3B series of industrial SSDs are SATA flash memory drives ideal for use as replacements for hard disc drives in industrial equipment and embedded devices. They provide high-speed performance, data reliability, storage lifespan, and data security at the highest levels in the industry.
