Toshiba introduces 32nm DDR NAND with 133Mbps speeds, or MT/s if you prefer
It doesn't quite have the efficiency and capacity of this 25nm process, and it's not half as speedy as that planned 400Mbps, but Toshiba is moving up in the world with today's reveal of 32nm, 133Mbps toggle-mode DDR NAND. The new flash memory chips will go head to head with the similar 30nm toggle-mode NAND used in Samsung's 512GB SSD and the 166Mbps ONFi 2.1 chips that power Crucial's RealSSD C300 drive; each of the tiny black chips can store up to 32 gigabytes. Shame there's no word on when we'll see these speeding our PCs and iPods, nor any mention of price. PR after the break.
Samsung's high-speed 512GB SSD to begin volume production next month
Does jargon like "Toggle-mode DDR NAND" mean anything to you? No, but a maximum sequential read speed of 250MBps and 220MBps sequential write speed scampering past a SATA 3.0Gbps interface should. Samsung claims that its new SSD is just as power efficient as its 40nm-class SSDs thanks to 30nm-class 32Gb chips and a low-power controller designed specifically for the toggle-mode DDR. Encryption? You betcha: 256bit AES. Expect to see the 512GB SSD hit production lines next month for an unknown (but not cheap) price.
