While 30GB doesn't sound like much storage space, I use that particular machine only for writing and it's always been optimized to reduce the load on CPU, HD and battery.

My wife (with a little hint) ordered a 30GB ZIF SSD kit for about $100 as a Christmas gift. I didn't have to look much further than OWC, the company that supplied the SSD I reviewed earlier. Besides, I've always wanted an excuse to open it up and see what makes it tick. It's a pain tracking down a suitable replacement, but given the fact that the current generation of this model of notebook starts at around $1300, I figured it was worth looking around. This is a first generation model, pretty pokey and with a small capacity hard drive that uses a hard to find ZIF connector.

Neither can be used for Bootcamp BTW, much to my disappointment.Following the success I had with upgrading my MacBook Pro's hard drive with a SSD (solid state drive), I decided to to try the same thing with my MacBook Air. The OS complains about improper ejection if I go through a shutdown, so I am wary about leaving irreplaceable data or complex running programs on either of them. The SD card seems able to shut itself down when not being accessed, hence minimal battery impact, so I leave it plugged in. The USB3 dongle is more versatile but my impression is it uses more battery, so I tend to leave it unplugged, and keep it in my bag. Also I can sell them on / use them on other computers. They're not perfect, but they do what I want for storing large files at the cost of a bit of battery life on my Air and a few mm of space. I have both the 128GB PNY storedge low profile SD card, and a 128GB mini USB3 sandisk low profile flash drive, both of which sell for a few dozen dollars. Probably would be cheaper to sell your Air and buy another 2013 model with the SSD space you want.

And if they are, either now or in the future, likely to be very expensive for what you get.
