First of all, hi to all i'm new to this forum. I want to explain my ssd experience. Last week i buy a G-Monster Photofast SSD 64GB ZIF 40pin for my macbook air rev.A and it works like a charm!! Macbook air now is a lot faster in all application and i get more battery life (about 20 minutes). I'm really happy with it and i haven't any kind of problem to install it (this ssd has the same dimension and connector of the original samsung HDD 80GB installed in macbook air rev. A). This is the only ssd 100% compatible with macbook air rev.A that i found. It's write also in their site that is compatible. Excuse me if my english is not perfect but i'm italian.
