TDK's new SDS1B series 6Gbps serial ATA compatible 2.5-inch solid-state drive is suitable for industrial applications, with NAND flash controller chip GBDriver GS1.
In recent years, the demand for fast, large-capacity data storage is increasing due to developments such as greater operating system overhead and HD high-capacity data application trends (such as 4K and 8K full high-resolution data broadcasting). . As the amount of data increases, industrial applications also increasingly require solid state drives with MLC NAND-type memories. In this case, along with conventional benchmark results, improved data retention and high reliability become important considerations.
To meet these requirements, the new controller not only has the recovery and refresh functions implemented by the existing GBDriver series controllers, but also comes standard with a well-accepted power interrupt tolerance algorithm and integrated power protection circuits. This ensures that both SLC and MLC NAND-type flash memories have highly robust data reliability. The new product does not require integrated DRAM or other types of caches to achieve read access speeds of up to 440 MB / s and write access speeds of up to 220 MB / s. * 1. As a result, the access speed of solid-state hard disk products has been greatly improved, which reflects TDK's rich experience and in-depth understanding of the realities of industrial applications.
Data security has also been enhanced. In addition to standard ATA security supplements, AES * 2 128-bit and 256-bit encryption and TDK's proprietary security features are also available. The company said that this makes it possible to store data in NAND-type flash memory in encrypted form to prevent the risk of data leakage and tampering, thereby achieving highly reliable storage security.
