At the end of the video you mentioned that Firewire fits in with eSATA port, right? From work experience I know that USB fits into eSATA port. You said you could connect some things interchangeably, but Fire and USB are incompatible with one another
A+ Storage Devices Part 1 - Firewire, eSATA, USB
Thanks for pointing this out! I'm now thinking this was a mistake I made intending to say that USB and eSATA were able to be directly used but meaning to differentiate this against Firewire800...but that's not what came out. Irony here though, I thought maybe I looked it up (googled it) to see if you could connect esata to firewire, today. I found this link: http://firmtek.stores.yahoo.net/spyderhub.html This was interesting to me. I'll post and errata to show soon.
p.s. with no additional activity on this post, I'm marking it as solved.
