    Does anybody know, whether the Fusion Drive's HD part runs at 7,200 rpm in the 27 iMac?

    Thank you

    Doubt it. After all from what I understand. most the time the data comes off the 'ssd' bit anyway.

    I think it's safe to assume that it is, in fact, 7200rpm. The specs list the non-Fusion HDs as 7200rpm. I seriously doubt they'd pull a switcheroo and use different, slower drives for the Fusion options, given that the upgrade cost to Fusion is the same $250 as it is for all the 21" iMac and Mac mini configurations for which it's available.

    Another reason: the reason Mac mini and 21" iMac use 5400rpm drives is because they're using 2.5" laptop drives in those. The 27" is using 3.5" drives (the existence of a 3 TB option proves this) and with 3.5" drives there's no real cost saving in using a 5400rpm.

    Yeah, I was just wondering because of bootcamp, where the SSD of the Fusion doesn't work.


    Thanks, but it doesn't really answer the question, or did I miss something in the video?


    Thank you, sounds very reasonable, hope you're right for the sake of Bootcamp.

    Fusion is effectively an SSD bolt-on to an existing 1TB drive (5400rpm in the 21-in, 7200 rpm in the 27-in) or 3TB drive.

    So yes, the HDD component of the Fusion setup would run at 7200 rpm in the 27-in systems.
