So I've pieced together a solution that works on Yosemite (Mac OS 10.10). Frankly I don’t recommend this.Seemingly simple, but couldn't get any of Google-able methods to work with my Macbook Pro.

If you really want fully isolated MacOS and Windows environments you could partition the blade SSD into two partitions.

This is where I would partition the drive into two volumes one for macOS (GUID) and the other FAT32, exFAT or NTFS (depending on what your needs are under Windows). The next aspect is where you store your apps & stuff! Here you want to limit the blade SSD to host your OS’s & Apps, leaving most of the drive empty! Then use your SATA SSD as your data store for both macOS & Windows. I would leverage the PCIe/NVMe drive as a dual boot running BootCamp so you can run both macOS & Windows on it. I would recommend you re-think your config. While that solves the drive config, you’ll still have issues with running macOS and Windows in the way you want. Mount the EFI partition of the OS X disk and copy your ist and kexts to the. This is because of a disagreement about time-keeping methodology between Windows and Unix-based operating systems. No matter how you change the clock in one OS, it doesn’t fix the problem with the other OS. So a single SATA or even PCIe/NVMe SSD’s limit is over come. This is a guide on how to get Windows 7 installed as a separate partition on an Intel MacBoot Camp Drivers:Boot Camp 4. After the installer is created, boot into it and install your OS X. If your system dual boots both Windows and macOS, you might notice that it’s impossible to get the system clocks to sync. This then gets into RAID where you aggregate multiple drives to gain better throughput.

So what you can see here is if you want something faster than SATA you need to get to a faster I/O channel in this case Thunderbolt, but that in its self doesn’t overcome the limits of the discreet drive’s I/O and its technology. The problem you are facing is the I/O speed of the interfaces (not the drives in this case) becomes the bottleneck! How to achieve the best transfer speeds with external drives, while this is more focused on external drives the I/O issues is the same internally as well. You will need to break the Fusion Drive set before you start and I also recommend you make a fresh TimeMachine backup as well to be safe.Īnd no, you don’t want a dual SSD Fusion Drive, that would be slower than running each discreetly. Here’s the guide you’ll need to follow to put it in iMac Intel 27' Retina 5K Display Blade SSD Replacement Yes, you can use the OWC Aura Pro X2 in your system.
