MacBook Air refresh could be sporting ultrafast 19nm Flash memory

The 2011 refresh may be incorporating NAND flash SSDs with transfer speeds of up to 400Mbps

More rumors are inbound on the inevitable MacBook Air 2011 lineup, this time dealing with special NAND flash chips supposedly embedded into the new models.

The new flash memory, according to AppleInsider, is said to be offering transfer speeds of up to 400Mbps. Called “Toggle DDR 2.0”, the 19nm chips may be soldered directly onto the motherboard and could replace Toshiba’s Blade X-gate SSD technology found in the current lineup of MBA models. Apparently, Apple will be one of the first major manufacturers to embrace Toggle DDR 2.0, as AppleInsider sources claim that most companies have yet to make devices compatible with the required standards and specifications.

Reports earlier in the year indicated that Apple silently updated some 2010 MBA models with a faster SSD supporting Native Command Queuing. If the Toggle DDR 2.0 rumors prove to be true, the 2011 lineup may see significant gains in boot up times and overall responsiveness compared to its previous generations.

The 2011 MacBook Air is reportedly already in production and could launch by the end of the month. By now, the refresh is practically no longer a secret, so here’s hoping Apple will officially announce the new generation of Air notebooks sooner rather than later.
