According to Samsung, 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; lab testing has shown it can reach reading speeds of 250 Megabytes per second, and a sequential writing speed of 220 Megabytes per second; both of provide three-fold the performance of a typical hard disk drive. Such speeds allow storing a standard DVD movie within 30 seconds.

“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. Due to the high-end specifications, experts estimate that companies that manufacture premium notebooks would show interest in the new product.

The new SSD makes use of reinforced 256bit AES (advanced encryption standard) encryption to ensure higher security, protecting personal data against online hackers or undesired access when its host PC is misplaced and/or lost. Another feature Samsung introduced is improved power efficiency. By developing a low-power controller specifically for toggle-mode DDR NAND, they managed to have the drive work with high-performance without increasing power consumption. The new controller also analyzes frequency of use and preferences of the user to automatically activate a low-power mode that can extend any given notebook’s battery life, for at least an hour.

Jun says that Samsung has put an effort to provide streamlined boot time and application access – resulting in an approximately nine-fold improvement (when comparing to regular hard drives). The design includes an intelligent operation management function, which optimizes the SSD’s background working environment. When coupled with the popular Windows 7 TRIM feature, the operation management function secures the reliability of the drive in write mode.

“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,” Jun concludes. Currently, no retail price was announced, since the product is yet to be delivered to stores.

TFOT also covered Toshiba’s 512GB SSD and OWC’s New SSD Storage Solution, a portable hard-drive that supports both USB and FireWire.
