It makes so much sense that the data your Mac wants most should be kept on faster-access media, and it seems silly to pay the higher price for SSD capacity to store lots of files which are seldom even read. But we know how Apple is: it'll be pretty solid out of the gate and then, assuming it's something the company wants to pay attention to, it will get remarkably better over the next 6 to 12 months, too.I’ve long been an enthusiastic user of Fusion Drives. The real benefit, of course, is dependent on how Apple has set up its algorithms to manage all this.

There are other hybrid models of blending SSD and mechanical disks to save money, but none of them are able to integrate with the OS and do it as intelligently as Apple is able to with Fusion Drive. This may be one of the biggest announcements of the day. But the benefit is that writes happen really fast because they're all going to the SSD. Then, of course, if the OS decides they belong better on the mechanical disk, that data will be moved at another time. Since the set up is already there, Apple added a v1.0 iteration (something I love): all write operations are first saved to the SSD. You'd have to reconfigure Fusion Drive, and it should work, but of course Apple's not going to support that. On the subject of replacement drives, Apple did indicate that there's nothing special (or, well different) about the drives in this iMac, so if your 3TB drive failed and you wanted to replace it you could, in theory, do so with 3rd party stuff. But if you don't have a backup, this setup (unlike a RAID) means you could go in and extract files from the working disk, though I would expect that to be a bit of a chore.

If you lose one of your drives (the SSD or the mechanical) you would need to do a full restore, according to Apple.

Well, Time Machine will back this up as one volume. Phil Schiller Demonstrates Fusion Drive Concept It does announce just one disk to the user (and to Applications), which means the OS does the management and you don't have to worry about it (but you should still back up). Disk Utility sees two physical disks, and the OS simply marries them together with Fusion Drive as a layer on top. This truly is the fusion of all the space on two separate disks.Īs I said before, this is all being done at the level of the operating system. If you have a 1TB mechanical drive paired with the 128GB SSD, you have a 1.12 TB storage platform. Cache would imply that the data on the SSD is duplicated, and it's not. To be clear, this is not a caching concept, at least not in the current use of the word. It will also take stuff that you aren't using all that often and moves it to the mechanical drive. This is not a simple RAID, however, as 100% of the "magic" is done within OS X itself. What Fusion Drive does is it watches what files and applications you run most regularly and it moves them to the SSD. Apple's initial incarnation puts a 128GB SSD in with either a 1TB or a 3TB mechanical drive. In a nutshell, Fusion Drive combines TWO drives, a solid state drive (SSD) and a mechanical drive. One of the more interesting things released today at Apple's event was the new "Fusion Drive" in the new iMac (and yes, it's only for the new iMac and new Mac mini models so far). Fusion Drive is Apple's take on solving the "I want the speed of an SSD but I have way more stuff than I can fit on the SSD I could afford" problem.
