Hmm so if I bought a new m1x with 2tb internal SSD, you're saying it's better not to have a core template using that 2tb internal SSD but to use it on a "template" external SSD?If the "internal" hard drive is the same that runs your system I highly suggest you not use it as your sample library hard drive.
The system drive, no matter the architecture of the processor, works a lot in the background, even if you're not using it. Running the operating system, the applications, the updates, the notifications, and everything that requires storage or virtual memory.
Having the sample libraries on the system drive, no matter the size means to slow and/or reduce the computer performance. Also, you have to consider that the sample libraries are data that every time you use gets read, and rewritten. This means that when you're using an X GB library you're subtracting that amount of GB from your system that has to "find" another spot for the background applications.
Having a bigger hard drive is not a solution, because the computer has to find the data necessary for its functionality in a bigger space.
The best solution is to have an internal hard drive big enough to contain OS + applications + 20% of free space. That's why you still have options to buy a new Mac with 256GB. Everything else should be located on external hard drives.
I personally have this configuration: System Drive + Time Machine, Projects Drive + 2 Backup, Library Drive + 2 Backup, Documents + 2 Backup. Every drive is 1TB. I'm still on spinning disks cause I still can't afford SSDs but I'm slowly upgrading my system. The concept does not change.
I hope this is helpful
Oh haven't heard of this. So I would have the Symlink folder pointing to an external SSD which I would plug in?Since you're on Mac, you can use symlinks to have all your libraries appear in one place regardless of where they are physically.
