Next MacBook Air to Adopt Faster, More Power Efficient SSD
The Japanese website Macotakara claims that the new MacBook Air will include SSD drive with adopted a new Toggle DDR 2.0 type of NAND Flash Memory.
Current SSD device Blade X-gale supporting SATA 2.6 will be abolished and new 19nm flash memory will be packaged into smaller chip and will be soldered on base circuit directly.
The new Flash chips will be built directly in the MacBook Air's motherboard; they support speeds of 400Mb/s, and will allow future controllers to run faster than today’s SSDs with "half the number of channels, providing both a cost and space savings", and could improve battery life for an hour or more.
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 more.
