Does it make things faster: yes Do you have to buy it: no I don't understand how people write long articles about Apple's pricing strategy. They can charge whatever they want and people will pay whatever it's worth to them. From the technical point of view: There is a nice Ars Technica post on how Intels SRT differs from fusion drive: http://arstechnica.com/apple/2012/10/more-on-fusion-drive-how-it-works-and-how-to-roll-your-own/ http://arstechnica.com/apple/2012/10/more-on-fusion-drive-ho... An excerpt: > Intel SRT does not handle writes this way—whether it's operating as write-back or write-through cache, SRT mirrors writes (immediately or within a short amount of time) down to the hard disk, which is not the observed behavior. Plus, as has been noted, SRT currently doesn't work with SSDs larger than 64GB. It is absolutely clear that Fusion Drive does not use SRT. As you can see, Apple does what it's best at: 1. Take existing technology 2. Improve it 3. Polish it 4. Sell it. It's this final touch, attention to detail and hassle free operation that people seem to be willing to pay premium for.
