TDK Announces SD3GB SSDs Are Coming In September w/ TDK GBDriver RS3 Controller
The SSD market just got a little more interesting as TDK Corporation recently announced that they will be launching a brand new SATA II drive called the SDG3B series in late September 2011. These new 2.5″ SSDs are considered industrial SSDs and they use a new TDK GBDriver RS3 controller on them. We aren’t sure about the specifics on this controller, but they are not equipped with cache memory, do feature 128-bit AES encryption and support an effective read speed of 160 MB/s. If you dive into the performance numbers you will quickly see that these drivers are not aimed at enthusiasts as drives equpped with MLC NAND Flash top out at just 25 MB/s on write speeds!
TDK enhanced 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.
