There's none. It's kind of like the "hello world" or "empty program" example for arrays.
What this page shows is that the CREATE ... DOES> construct is similar to a closure, except it can only capture one address (or reference in languages that don't want you to dirty your hands with addresses ;-) and it is always a global symbol (like almost always in Forth). It is still useful to encapsulate implementation details, though.
Some people have said it is a basis for objects, which is a bit euphoric IMHO. You know, "closures are the poor man's objects, and objects are the poor man's closures".
SATA ports are often rated for only tens to hundreds of cycles, so they're often made out of fallapartium.
If you're replacing one, it's easiest to cut all of the plastic off first, then desolder the contacts one at a time. Sometimes you can even pull the plastic off, without damaging it. It's usually necessary to preheat the board.
Things like that are often the only through-hole components on a PCB.
I like to melt the original solder one contact or area at a time, add a little bit of fresh flux-containing solder if needed, and as soon as it gets to the consistency of mercury, vacuum it clean out with a good soldersucker.
