Hi, new member here, got my i5/8/128 haswell MBA today. The Blackmagic disk test shows 306-317 Write and 717 Read. Is the write speed low? However the macbook seems to be ultra fast, with 16+ hours battery life by the virgin boot! No choppiness at all, may be a little on huge facebook scrollings . The question is: Let's say I would like to install Mavericks soon. But I want to install software on here (Mountain Lion). Is there a way to move the software from MLion to Mavericks during the installation? Thanks, sorry for my English.
