Editting with SSD external drive

Thats a broad question indeed. My workflow is a s follows on one of my Mac Pros:

3 x Samsung EVO SSD's. One for OS, one for footage files brought into AE & NLE and the other as the scratch disk for PP, AE, C4D etc etc

If your external SSD dies not house your OS as I expect it doesn't then use it as either the drive your footage is on (which will help with speed). Or if you have another SSD thats reading your footage files use that external as a Scratch Disk

I think you probably will be using it to store footage files and read from that.

Please let me know

Thanks
