    Hello,
    In a few weeks I`m planning to buy my first ever Mac computer, the 27 inch 5k iMac. My main concern is the disc - should I get the HDD or SSD version? I know that the SSD is much faster, but will it actually affect performance apart from faster boot speeds/some apps loading faster etc? And if it does, then how big is the impact? I`m not looking for read/write speeds, I know that the HDD has much lower i/o speeds - I want to know exactly how it will affect my experience with the computer.

    Get one with the SSD or Fusion drive. It does make a noticeable difference with general system performance.

    Here's a tidbit:

    ! have a late 2013 iMac with a Fusion drive. In most respects, it's just as fast as an SSD-based computer for everyday use. A couple of days ago, the HDD started to generate bad clusters and I had to revert to a clone backup on a Thunderbolt-based HDD, which should be just as fast as a non-Fusion, non-SSD, iMac.

    Considerable difference in performance, especially watching it boot up.

    The only drawback I see with Fusion drives is that it's more complex - and with two pieces of critical hardware, your chances of a failure go up. In my case, it happened to me. I just got lucky and caught it in time and brought it in. Where, by the way, Apple has the most hilarious test software:

    SSDs are pretty unlikely to fail as far as I know, so it's really just one part (the platter drive) you have to worry about.

    With my experience with other flash based memory, any failure is likely to be catastrophic - though I have yet to suffer a failure of an SSD. I've been able to coax a lot of data off of failing platter drives. I do agree that an SSD will likely outlast an HDD - and in certain applications like laptops, they are a no-brainer.

    Any new machines I purchase in the future will be SSD based. My 2012 rMBP sold me on that.

    ...just this week, I bought an iMac. And, this is coming from someone that has never owned a Mac. I bought the 27", cheaper model, with the SATA 1TB drive. I was under the impression with the extra processing power, up from a MacBook Pro (I bought that last week), it would help.

    As soon as I powered it on, I noticed how s l o w the iMac was. I got an SSD from work, and used an enclosure, closed the OS from the 1TB drive, and used the SSD as a the default drive. Talk about night and day, or Apples to Oranges.

    Get it with SSD, even more so 'for the future'. To give you an example:
    Boot with SSD = 27.36 seconds
    Boot with 1TB SATA = 34.22
    Opening Outlook 2016, with SSD = 5.0
    Opening Outlook 2016, with 1TB SATA = 8.63

    I know you weren't looking for 'stats', but...
