Alex Rettig Posted August 6, 2018 Share Posted August 6, 2018 (edited) Thinking to Fusion Drive of two internal SSD. There are some interesting cases: On iMac Fusion Drive: The original Fusion Drive SSD replaced with SSD NVMe PCIe plus adapter, and SSD SATA in replace of HDD. On Mac Pro: One SSD SATA with OWC Mount Pro plus a SSD NVMe with PCIe card adapter. This configuration allow a Mac Pro (2006 to 2012 models) to take true benefit from NVMe PCIe SSD: Since The Mac Pro can not boot from NVMe (there are rEFInd and Clover "patches", but Fusion Drive give us better data integrity and usability, and is the easier configuration) Concerns: NVMe SSD can be more fast (and more big) than the original Apple's Fusion Drive on iMac. NVMe SSD can be more big than the HDD drive on Mac Pro. Both cases contradict the Fusion Drive argument supposed to be: "SSD is always the small disk and the faster one, HDD is always the big disk and the slower one" So, how does Apple Fusion Drive technology to detect the fastest drive and to optimize the resulting logical volume? Any detailed Apple specs document of how fusion drive technology optimization works? (Please share documented answers, thanks!)
