The instructions on tumblr are quite heady, so it will help to be computer hardware and programming geek.

In a nutshell, the DIY set up allows the first megabyte of data to be read from the SSD and then the rest of the data is read from the HDD. That ability combines the best of both worlds giving users the speed of a SSD combined with the high storage capacity of the average traditional hard drive.

Apple's Fusion Drive tech gives Mac users a 128 GB SSD and a larger hard drive ranging from 1 to 3 TB of capacity. Software on the Mac computer keeps track of which files and applications are used frequently and physically moves those files and applications from the hard drive to the faster SSD to improve system performance.
