Samsung Electronics Co., Ltd., the world leader in advanced
semiconductor technology solutions, today introduced the first solid
state drive (SSD) utilizing high-performance toggle-mode DDR NAND. The
new 512 gigabyte (GB) SSD provides electronic data processing
application designers with advanced performance and reliability for
notebooks with premium value.
“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 DVD
movies (approximately 4GB each) 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
The Samsung 512GB 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 lost.
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.
