512GB SSD achieves 250MBit/s read speed

Samsung Electronics Co. Ltd has developed what is claimed to be the first solid-state drive (SSD) using high-performance toggle-mode DDR NAND.

The latest 512GB SSD provides electronic data processing application designers with advanced performance and reliability for premium-value notebooks.

The 512GB SSD makes use of a 30nm-class 32Gbit chip that the company began producing last November.

The toggle-mode DDR structure together with the SATA 3.0 interface generates a maximum sequential read speed of 250MBit/s and a 220MBit/s sequential write speed, both of which provide three-fold the performance of a typical hard disk drive. At these speeds, two standard length (approx. 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 16Gbit 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 reinforced 256bit AES encryption to ensure higher security, protecting personal data against online hackers or undesired access when its host PC is misplaced and lost.

The company also provides streamlined boot time and application access with the 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.
