Samsung has unveiled a new 512GB SSD to its range that makes use of its new toggle-mode DDR NAND storage. The use of DDR allows the bandwidth to be doubled without increasing power consumption, allowing for an improved power efficient controller that uses this DDR NAND.
The 512GB model makes use of Samsung’s 30nm 32Gb NAND chips, which it began producing last November. The SSD features sequential sequential read and write speeds of up to 250MB/s and 220MB/s, respectively, with roughly a 9-fold improvement in random access performance of hard disks and with Windows 7 TRIM support.
For security, the 512GB SSD uses internal 256bit AES encryption, such that once a drive password is set, hackers will not be able to extract data directly from the NAND chips.
So far no pricing information has been announced, but with SSDs priced proportional to the capacity due to the high cost of NAND, expect the price to be roughly their 256GB model. Further information can be found in this MyCE story and on Samsung’s press release.
