Updated MacBook Air to Offer Minimum of 128 GB SSD and 4 GB RAM?

Concord Securities analyst Ming-Chi Kuo today reported to AppleInsider that "industry checks" within Apple's supply chain suggest that the company is boosting the specs on its MacBook Air in the expected refresh to a minimum of 128 GB of solid state storage and 4 GB of RAM. That refresh has been widely rumored for some time, with Apple reportedly holding off until OS X Lion is released to the public to launch the new MacBook Air.

In a communication to AppleInsider on Thursday, Concord Securities analyst Ming-Chi Kuo said his industry checks suggest Apple is no longer placing orders MacBook Airs with 2GB of RAM. Instead, those checks indicate that all new 11.6- and 13.3-inch models will include 4GB of RAM as standard, as it will improve performance of Mac OS X Lion, also due to ship on each model.

Similarly, Kuo cited the same checks in suggesting that Airs with just 64GB solid-state-drives may go away in favor of Apple shipping only 128GB and 256GB models as standard, given that the bulk of Apple's shipments have been for models containing those larger drives.

The current MacBook Air models all carry 2 GB of RAM in their stock configurations, although they can be upgraded to 4 GB for $100 on build-to-order configurations. On the storage side, Apple's entry-level 11.6-inch model offers 64 GB of solid state storage, with users able to step up to 128 GB on the high-end model. The 13.3-inch MacBook Air already offers a minimum of 128 GB with the high-end model sporting 256 GB.

Kuo also indicates that Apple will continue to use a separate board for the solid state drive rather than shifting to new technology soldered directly onto the motherboard. He also suggests that Apple will likely adopt the following Sandy Bridge chips from Intel for the updated MacBook Air models: 1.6 GHz Core i5-2467M, 1.7 GHz Core i7-2637M, and 1.8 GHz Core i7-2677M.

Kuo has proven to have solid connections when it comes to MacBook Air information, as evidenced by his revelation last July that Apple was working on an 11.6-inch model, a machine that appeared alongside a revamped 13.3-inch model in October.
