    Hello MacRumors friends. What happens if you remove the hardisk of a Fusion drive and made it into an external drive?

    Fusion drive between NVMe and SATA SSD?

    My late-2015 27" iMac has been feeling slow lately when there's a lot of disk access going on (like when running VMWare). It's pretty clear the bottleneck is the existing 2.2TB fusion drive. I was thinking of replacing the stock drive components with a 2TB NVMe, but then was wondering if some...
