Samsung is set to ship a new high-speed solid-state drive that can hold 512GB of data, as these drives begin to standardize at higher levels of capacity.
Samsung, currently considered the leader in solid-state drive market share and technology, is touting a new development called "toggle-mode DDR (double data rate) NAND," which the company says allows high-performance without a corresponding increase in power consumption. (NAND technology is synonymous with flash memory, used widely in high-end smartphones such as Apple's iPhone.)
"Toggle mode NAND uses a synchronous interface as opposed to an asynchronous interface of standard NAND thereby permitting a larger bandwidth," said Gregory Wong, president of Forward Insights, a consulting and market research company, which specializes in NAND memory.
Wong continued. "The standard NAND interface is about 40 Mbps (megabits per second) and is a performance bottleneck for performance-oriented systems such as SSDs. The toggle mode DDR2 NAND is 200Mbps. This means that you can achieve the same SSD performance with toggle-mode NAND as with a standard NAND interface with a lower-power footprint," he said.
Intel and Micron Technology offer analogous technology with their SSDs, Wong said. … Read more
