Samsung Electronics on Thursday introduced the first solid state drive (SSD) utilizing high-performance toggle-mode DDR NAND. The new drive, which will initially be available in 512GB capacity offers rather unprecedented performance; besides, the world’s largest maker of flash memory also promises improved reliability and advanced security.

“Early introduction of this state-of-the-art toggle DDR solution will enable Samsung to play a major role in securing faster market acceptance of the new wave of high-end SSD technology,” said Dong-Soo Jun, executive vice president of memory marketing at Samsung Electronics.

The SSD utilizes 30nm-class 32Gb chips that the company began producing last November. The toggle-mode DDR structure generates a maximum sequential read speed of 250MB/s and a 220MB/s sequential write speed. The latest SSD from Samsung can also be equipped with 256-bit AES (advanced encryption standard) encryption engine to ensure higher security. As all the latest drives, the novelty fully supports Trim command that preserves performance of SSDs in the long run.

The new drives are based on low-power controller specifically for toggle-mode DDR NAND. The resulting power throttling capability enables the drive's high-performance levels without any increase in power consumption over a 40nm-class 16Gb NAND-based 256GB SSD. The controller also analyzes frequency of use and preferences of the user to automatically activate a low-power mode that can extend a notebook's battery life for an hour or more.

Samsung plans to begin volume production of the 512GB SSD next month. Even though initially toggle-mode DDR NAND-based SSDs will be available at premium price-points and with premium capacities, over time it can be expected that they will become more affordable and address mainstream capacity points.

"The highly advanced features and characteristics of our new SSD were obtained as a direct result of an aggressive push for further development of our NAND flash technology, our SSD controller and our supportive SSD firmware," added Mr. Dong-Soo Jun.
