In early November, 2012, Apple issued a graphics update for all mid-2012 MacBooks. In a continued streak of stupidity, however, this update forces your Mac to use "Safe Sleep". This means that the entire contents of your RAM is written to your disk every time you put your Mac to sleep.
This is retarded on the scale of the Titanic's navigational plan for two reasons:
1) Your Mac likely has 8 or 16GB of RAM. This is a ton of wasted disk space; especially on MacBook Airs that ship with only 256GB SSDs to begin with.
2) SSDs wear out as you write to them. Each cell of a SSD can only be written to a certain number of times before it becomes read-only. If you put your computer to sleep many times a day, OS X is slowly but surely destroying your SSD with unneeded write cycles.

It took me some time to arrange things to work properly so I wanted to share my work in case it helps anybody.
