Fusion Drive, no one needs your fragile combination of storage technologies anymore. If Apple had really believed in you, they would have made you the default storage system on a Mac, any Mac. Instead you were neglected to a build-to-order-option. Even the top-of-the-line 27 inch iMac never shipped with a Fusion Drive standard. Fusion Drive, we will always remember you for the fast plentiful storage you promised. A great idea whose time came too late. - Egg Feckles
Two weeks ago I removed my MacBook Pro’s optical drive and replaced it with a home made Fusion Drive. A 256GB SSD in the hard drive slot, and a 750GB platter instead of the Superdrive. Combined I’ve now got a blazing fast 1TB MacBook Pro.
So, although I’m still convinced my classic MacBook Pro will be removed from the line-up once the new Retina MacBook Pro’s are released, for now, this machine (it’s a late 2012 model) is my favourite MacBook Pro ever. It’s fast, has every port I need, and runs stable and smooth.
Sure I want retina, sure I want all day battery live, sure I want a machine half as heavy. But given this machine is based on old school technology, and still run this smooth, I can see where Apple’s Fusion Drive technology originates from. If you want and need as many storage as I want, and don’t want the complexity of external drives, Fusion is the way to go.
The machine boots almost as fast as an Air, so the illusion of SD speed is there, but it gives you plenty of storage for a reasonable price.
And the so called risk? Well, if I didn’t create the Fusion Drive I would probably either have only an SSD or a HD. If it breaks I need to fix it. So nothing changes here. One drive, one point of failure, and plenty of backups to run too.
So all in all, I'm a big fan of this technology. It’s thinking different at its fullest.
Note: If anyone’s interested, I’ve created a Fusion Drive with recovery partition included. I’ll post the recipe later.
