I was working on a little project, getting more storage into the MacBook Air. The 13" MacBook Air has the SD Card slot, as you all know. When I bought it I thought I'd just pop a 32GB SD in it permanently and leave it there. However, to my surprise, it stuck out half way and this killed the purpose. So I did some googling around for a while and couldn't figure anything out. There was another topic on here that said to get a Micro SD / USB / SD card adapter and cut the USB half off and it would fit flush and use a Micro SD card with it. This sounded like a good idea however the OCX card they were looking for was out of stock everywhere, nowhere to be found. And then I found an alternative on eBay from Norcent. Step 1. Buy this: http://cgi.ebay.com/ws/eBayISAPI.dl...85688&ssPageName=STRK:MEWNX:IT#ht_1971wt_1156 It's $8. Step 2. Buy a 32GB Micro SD. I got a Lexor 32GB Class 10 from Amazon for 90$ however you can get a class 4 for around $50. Or get a 16GB if that's all you need. Step 3. Cut the USB end off the Norcent adapter. With scissors. And maybe sand it down to make it smooth if needed. Step 4. Put the Micro SD card in the Norcent adapter. Step 5. Put the Norcent adapter in your SD card slot. You will need Tweezers to remove it, but it fits flush and is great for some extra permanent storage for those of you that might run low especially with the 128GB SSD. And yes, I've done this, and it works. Supports SD, SDHC, etc. My Lexor 32GB Class 10 works like a champ.
