The teardown experts at iFixit have just taken apart the new 13-inch Mid-2013 MacBook Air that was announced at Apple’s Worldwide Developers Conference keynote yesterday, and while there aren’t too many drastic changes in the internals there are a few differences that are worth noting.
The team found that the PCIe-based SSD module from Samsung is smaller than the previous model’s Toshiba SATA module, which also means that the drive is not compatible with previous MacBook Air models. As noted earlier by AnandTech, the read/write speeds of the flash storage approach 800 MB/s.

When Apple announced the Haswell-based MacBook Airs yesterday, perhaps the main highlight of the introduction was the “all-day” battery life topping out at 12 hours for the 13-inch model. And while the processors are a large part of the claimed all-day battery life, iFixit found that the new Airs also sport batteries with increased capacity driven by higher voltages: increasing from a 7.3 V, 6700 mAh power battery to a 7.6 V 7150 mAh power battery.
Other changes that the iFixit team found include a redesigned AirPort card that provides 802.11ac Wi-Fi and an expanded heat sink covering both the CPU and platform controller hub (PCH), although the PCH does not have any thermal compound applied to assist with transferring heat to the heat sink.
The 11-inch MacBook Air starts at $999 with a 128 GB hard drive, while the 13-inch MacBook Air starts at $1099 with a 128 GB hard drive. Both lines are available at Apple’s Online Store and at the company’s retail outlets.
