“The new MacBook Airs are due any day now, and I’m excited about them, especially if reports are true about some high-end tech they’ll be using,” Dennis Sellers reports for MacNews.
“Apple will adopt ‘Toggle DDR 2.0,’ a 19-nanometer process for NAND flash memory, according to a a report from the ‘Macotakara’ web site,” Sellers reports. “Toggle DDR 2.0, an industry first, sports 64-gigabit flash chips manufactured using 20nm processes that boast a 400Mbps transfer rate. That makes these toggle DDR 2.0 chips about three times faster than toggle DDR 1.0 (a 133Mbps interface) — or 10 times faster than the 40Mbps SDR NAND flash currently in use.”

Sellers reports, “Apple’s current SSDs offer read and write speeds of over 200MB/s, more than four times the 400Mb/s — or 50MB/s — offered by Toggle DDR 2.0. Apple would be chaining multiple chips together, however, providing the performance required to match or exceed today’s technology, according to the ‘thinq’ web site.”
