2017 iMac fusion vs Samsung T5 ssd

[Jungles999]

hi all

I just bought a 2017 iMac with 1tb fusion and I’m happy with its performance for my needs

But I’m getting the chance to buy a Samsung T5 500GB ssd for very cheap

Would I be better off

1. Booting the os and everything on the external ssd

2. Leaving the boot drive and applications on the fusion drive and using my external ssd for files.

I know the thunderbolt 3 drives are the best to use but they’re too expensive in England and I don’t know if I need that kind of speed.

It all depends on your apps and file sizes. Booting from a T5 will be slower for most users than the fusion when new. When the FD gets too full or your files are too big then the FD will be slower.
