Pros: - Fits snugly into the MacBook Air (13.3") SD card port - you can barely tell the port has something in it. With the card in place, the laptop goes into the snuggest case without a problem. - (Although writing speed is a bit slow), once the data is on the card, retrieving it quickly is no problem - I have played music and videos off it without any problem at all. - The price difference between the 128GB and 256GB versions of the MacBook Air (on Amazon) is over 20,000 rupees. This card gives you that same additional storage at barely 30% of that amount. What's not to like? :)
Cons: - Writing speed is a bit slow. - (Downside of the snug fit) Taking the card out is NOT easy, since one can get hardly any purchase on it. My idea is to leave it in place, but it is not ideal for anyone who wants to keep taking it out often.
