guys im just a noob to mac. A little helo without sacasm would be appreciated.
But the screenshot you took was on the page, which explained what Thunderbolt is. Is that not understandable?
Simple explanation: It is an interface to connect a computer with an external HDD, just like USB 2.0/3.0 or Firewire 400/800, but offers much faster speeds than USB or Firewire. Therefore those external HDD enclosures using Thunderbolt come with several HDDs, that way they can be used in RAID (combining several HDDs into one) to get faster read and write speeds.
USB 2.0 offers 35 MB/s, Firewire 800 offers 65 to 75 MB/s, Thunderbolt offers almost 1 TB/s.
The other advantage is also connecting several Thunderbolt devices in a chain (daisy chaining) and still have fast transfer speeds.
Is the above understandable?
The below is from the same page you already visited:
And a hello without sarcasm is rare, especially with cases, where a simple answer can be found via search (which is faster than creating a thread here, or registering here) or reading the contents of the site you already visited and took a screenshot of. How can we know, what kind of knowledge you have. Maybe you don't know anything about computers, thus not understand anything on the Thunderbolt page (the one you visited and took a screenshot of). If that is the case, you may never need the Thunderbolt port.
