    Amongst the many new products Apple introduced today, they also announced a new storage option called Fusion Drive. Apple's website describes how the drive works:
    Some thought the drive might be Apple's implementation of a Hybrid drive which uses SSD as a caching system, but it appears that Apple's system is distinct. The MacObserver digs into some details and clarifies:
    Ars Technica compares it to an enterprise feature called Automated Tiered Storage.
    The Mac Observer reports that there are two separate drives that appear as one logical partition. As a result, if your Hard Drive fails, it could be replaced with a 3rd party drive and reconfigured as a Fusion Drive.

    Meanwhile, they note that all writes take place on the SSD drive, and are later moved to the mechanical drive if needed, resulting in faster initial writes. The Fusion will be available for the new iMac and new Mac mini models announced today.

    This feature is perfect during this HD to SDD transitional period. It'll keep things affordable while still supplying great performance.

    Personally, an SSD boot drive and separate large HD seems more practical. No need to "fuse" them into one volume. Just seems like asking for trouble.

    According to Apple's specs page, it's also configurable on the high end 21.5" iMac as well.

    The way I see it, this is a variation of what OS X has been using for a long time: moving frequently used files to the faster "hot zone" on the outside of the drive (faster rotational speed). But here, the "hot zone" is a separate flash storage drive instead of being on the same hard disk. But sounds like cool technology. Is it all contained in a single unit? Can it be replaced easily, or as a single unit?

    Unfortunately, where I need speed is for my ~150 GB of RAW photos, and it looks like the flash storage component is too small to fully benefit me there. The hard drive on my 2011 iMac is deathly slow, my MacBook Air is WAY faster, despite technically being much lower-specced. That SSD makes all the difference in the world.

    Very interesting, though I'm wondering what if one of those drives fail. Is your data retrievable from the other one?

    The higher end 21.5 iMac can be configured with a 1 TB fusion drive as well.

    I really hope this feature becomes available to other macs that have an SSD and HDD already installed. Even the previous generation iMacs you could have an SSD and HDD installed by Apple. If they open it up to other computers, I'll look forward to installing it on my Macbook Pro with the dual drives instead of the optical drive.

    Don't mistake it though. You'll still lose all your data.

    prices of SSDs went down heavily

    This is actually not needed if apple went with 256GB as standard :rolleyes:

    The fusion drive is just software to automatically handle that. Most consumers probably don't want to have to deal with having a boot drive and a data drive. Some things can be tricky to get onto an external drive, like iTunes and iPhoto libraries.

    Exactly my thoughts... good temp solution.

    Way cool technology aside, is anyone else curious how VMWare feels about the name?

    Outside of the drive spins faster, but I know what you mean.

    How would having a 256GB SSD replacing having a 1TB or 3TB hard drive?

    Wonder why no larger SSD option, especially since you can get a much bigger SSD alone. There must be some sort of balance between the SSD and HDD components in the Fusion configuration.

    I agree. Perfect for now until SSDs drop in price.

    most of us do not need that bigger size as main drive, you always need to backup the data into some external drive.

    I hope they make this available for existing products. I'd love to replace the drive in my 2012 mac mini. It sounded like it was mountain lion doing all the work and not new hardware, other than the drive. Does anybody know if this is the case.

    I'm not too happy with the current price for the fusion upgrade ($250 for the mac mini). I hope it will be less for the 27" iMac...but I'm not going to hold my breath.

    Will I get the upgrade? Yes... Getting the stand alone SSD is not enough space for what I need and this seems like a good solution for the time being.

    Excited to see some benchmarks about this! I currently use a drive like this and wonder if this one is any better! :cool:

    It looks like Intel's Smart Response Technology (SRT)

    and most likely that's exactly what it is. It has been available on PCs for a while.

    Yeah, sorry about that, I realized my mistake and already fixed it.

    It does seem to be more of a software solution then. Wonder if it will be something that is added to Disk Utility to be able to do on other systems with dual drives. Nah... This is Apple so probably not :)
