Toshiba Touts New DDR Toggle Mode NAND
Getting down the technical nitty gritty, Toshiba claims its new chips can shuffle data around at 133 megatransfers per second (MT/s), which is more than three times the 40MT/s of current generation SLC chips. A threefold increase is nothing to sneeze at, folks, and could render a good many currently-shipping SSDs obsolete, at least in SLC form.

As Toshiba explains it, the asynchronous interface means there's no need for a clock signal, and that's how these chips consume less power with a simpler system design compared to synchronous NAND alternatives. Toshiba also says it managed to reduce crosstalk, a problem that typically creeps up at faster speeds.
"Scalability to future high-frequency operation is enabled as a result of the bi-directional data signal," Toshiba explains.
Toshiba didn't offer up any details on ship times, but did say it will have 32Gb (4GB), 64Gb (8GB), and 128Gb (16GB) capacity chips in SLC form, and 64Gb (8GB), 128Gb (16GB), and 256Gb (32GB) in MLC form.
