Samsung Introduces 512GB SSD Utilizing Toggle-mode DDR NAND Memory


Samsung today introduced the first solid state drive (SSD) utilizing high-performance toggle-mode DDR NAND.

"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," said Dong-Soo Jun, executive vice president, memory marketing, Samsung Electronics. "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," he added.

The new 512GB SSD makes use of a 30 nanometer-class 32 gigabit chip that the company began producing last November. The toggle-mode DDR structure together with the SATA 3.0Gbps interface generates a maximum sequential read speed of 250 Megabyte per second (MBps) and a 220MBps sequential write speed, both of which provide three-fold the performance of a typical hard disk drive. At these speeds, two standard length (apprx. 4GB each) DVD movies can be stored in just a minute.

Samsung provides further gains in power efficiency by having developed a 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.

The Samsung 512GB SSD makes use of 256bit AES (advanced encryption standard) encryption to ensure higher security.

Samsung also provides streamlined boot time and application access with this new SSD, showing an approximately nine-fold improvement in random performance over HDDs. Also, an intelligent operation management function optimizes the SSD?s background working environment. Coupled with the popular Windows 7 TRIM feature the operation management function secures the reliability of the drive in write mode.

Samsung plans to begin volume production of the 512GB SSD next month. The new capacity extends Samsung?s range of SSD densities from 64GB to 512GB.
