TDK Corp. has announced the launch of the SHG4A series of half slim type solid-state drive (SSD) modules for industrial applications. The new NAND flash memory modules support the serial ATA II standard and enable storage capacities of up to 128GB also with SLC type NAND flash memory. The modules are about one half the size of a 1.8” hard disk drive (HDD).
The SHG4A series of half slim type industrial SSDs employs the standard SATA connector also used for 2.5” type SSDs, which eliminates the need for a special connector at the customer's host side. The GBDriver power interruption tolerance algorithm which has won high acclaim especially among industrial users, and an integrated power supply protection circuit are standard features, making this compact SATA flash drive resistant against power supply problems, a highly desirable characteristic for demanding industrial applications. The modules measure approximately 54mm * 40mm.
The addition of the Enhanced ECC function and a read retry function for enhancing data reliability are major advantages of the new products, augmented by features of the existing GBDriver series such as auto recovery, data randomizer, and auto refresh. Integrated control of these functions enables the product to easily accommodate coming trends in flash memory.
The sophisticated static wear leveling algorithm averages the write and erase process over all blocks of the memory area, thereby drastically improving the lifespan of installed flash memory. SMART (self-monitoring & analysis reporting technology) provides information about the number of times that memory blocks have been programmed (erased), which facilitates quantitative lifespan management of flash storage.
Data security has been further enhanced by the addition of AES 128-bit encryption and a TDK proprietary security function to the standard ATA security complement. 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 SHG4A series of half slim type industrial SSDs are SATA flash memory drives ideally suited for use as replacements for hard disk drives in industrial equipment and embedded devices. They provide excellent performance in all vital aspects, including high-speed performance, data reliability, long storage lifespan, and data security.
