Seriously people, get a clue. Unless you win the lotto, that is not an option.

And holy shit - the guy defrags an SSD? (thats bad if you know anything about SSDs)

Dont' get me wrong, I'm excited about SSDs too, and can't wait for them to be affordable. But that video.... oh man. Talk about off the mark.

The guy defraged an SSD that did not cost him anything and he was willing to jump and down on a trampoline with. True SSD'd do not need degfragging they can access all parts of the drive at the same time. Defrag writes like crazy and would just get you closer to your write limit.

The only unreasonable hardware might be the custom memory other than that most of the stuff on there is not that far out of reach. I have had top of the line computers before and am looking at building one now. The only unrealistic thing is well 24 drives at $700 a pop.

Defragging rearranges the data in sequential chunks.

The file structure on SSD's are mapped to relatively random locations due to wear leveling techniques used by the manufacturers to increase the lifespan of the SSD. If you defrag, you'll be doing a whole bunch of reading and writing to move stuff from one random order to another random order, causing wear to the flash in the process.

Not to mention SSDs dont overwrite the data stored in the cells(normaly) so if you format and/or defrag a drive you will see reduced performance since the drive will have to first empty the cell being written to and then write to it. It's actualy quite a large problem with the current technology.

I'm not sure if they've fixed that with the new generation coming out, but it was still a problem 5 months ago when I bought mine from Vertex.
