Ahaa, gotcha. The reason why I was a bit ‘confused’ about an external meaning, is whether it MUST be external by means.
On the other hand, the whole idea here is just to keep specific files (cache in this case) on a different drive, disregarding their ‘physical’ appearance.
With that said, for a cache, you will definitely see a difference with SSD over HDD. Take a look at this article, conclusions section: AE Disk Cache Performance
1. Use at least an SSD for your After Effects Disk Cache. Not only will you be able to finish writing to the
disk cache 2-3 times faster than if you were to use a platter drive, but you will also be able to play both
cached and uncached compositions significantly faster (anywhere from 15-30% on average)
2. Faster NVMe drives can give moderate performance gains in some situations. It certainly is not across the board,
but faster NVMe drives can allow you to finish writing to the disk cache up to ~20% faster
and may let you play uncached compositions a bit faster (~5%)
Now talking about USB 3.0 vs Thunderbolt – maybe someone has an objective opinion, as I haven’t ran any comparisons myself, nor am familiar with both.
