Upgrading from 2TB Fusion Drive to NVMe/SSD Blade/PCIe SSD/M.2
I am considering buying a used late 2015 iMac. The specs are:
- 2TB Fusion Drive
- 24GB RAM
- AMD M395
- i5 3.3 GHz
I currently have a MacBook Pro Retina, with SSD blade, and it is fast! I'm afraid that the late 2015 iMac would be slower in terms of read/write speed, since it has a HDD (Hybrid: HDD and SSD).
My Questions are:
- Is it possible to upgrade the iMac´s Fusion Drive to a for example Samsung 960, or do I need a specific Apple NVMe flash drive for this? And in addition have an SSD to replace the HDD
- Does the Mac come with the SSD slot?
- If the iMac is equipped with Fusion Drive, does that mean that the iMac already has the SSD Blade installed? If so, how many GB is it?
One more Question
- I read the the 1TB Fusion comes with a flash drive, but only 24GB, and the 2TB comes with 128GB.
My question is, is it possible to "Separate" the drives, so that in finder, I can have two volumes.
I "accidentally" split the Fusion Drive. And wasn´t even necessary using Terminals. Take a look:
I just selected "Fusion Drive" from Disk Utility, then did a 128GB partition. After that, I got two separate disks - separating the HDD and SSD. Erased both drives to APFS.
So I named the SSD "MacOS". Installed the OS to that. Then moved my "Home" directory to HDD.
This configuration now makes sense to me. Got all my programs on the SSD, then movies, documents, pictures etc are "automatically" re-directed to my 2TB HDD.
Don´t think I need to upgrade the hardware.
