Apple's fancy new Fusion Drive promises to couple an SSD with a traditional hard drive for large-scale storage with lightning fast boot up and program launches. But a developer found Mountain Lion already packs support for Fusion Drive, meaning that with an SSD, a hard drive, and a bit of Terminal magic, you can create your own homebrew Fusion Drive right now for your old Mac.
The process, well, it isn’t exactly plug-and-play, and you'll need to know what you're doing with the Terminal version of Disk Utility, but it doesn't sound that complicated. There's no telling whether Apple'll give you an easier way to do it in the future -- a Fusion Drive utility of some sorts -- or whether some enterprising developer will create a tool for us all, but I wouldn't use this for your primary setup just now.
Still, a speed boost for your old Mac without having to fork out horrendous sums on a large SSD sounds like a great plan to me, especially if the Fusion Drive actually works as promised, unlike other lame-duck SSD-hard drive hybrids. [Patrick Stein via Apple Insider]
