Can I upgrade my MBA to a larger than 256GB SSD? Specs are: 2.17Ghz 8GB 256GB

Here’s a 480 GB drive that should work for you: http://eshop.macsales.com/item/OWC/SSDAP

The SSD is proprietary and changes every year, but yes it can be done. You will need to match the year up to get the right SSD or use the model number to make sure you are buying the right one. To open the laptop, you will need a P5 Pentalobe screwdriver.
