run macos from external harddrive

[Cupar19]

would running macos from an external usb 3.0 drive be usable, similar to running normally. the drive gtes an average of 80MB - 105 MB transfer speeds (dont know if that matters though)

OSX on any HDD is gonna be slow. But a usb won't be much slower than a internal ones. Get a ssd.

 

You can't comapare the sequentical speeds, the os looks at random iops, and there much slower than any ssd.

These are sequential read speeds. When dealing with many small files, you're not going to get these kind of speeds. You would also need to take a look at the IOPS.

 

I wouldn't run from it from an external drive. The performance is usually not satisfactory.
