somebody is not telling me the whole story:
Quote:

Researchers aren't the only ones excited about blazing data speeds. This record speed of 6.63Gbps is equivalent to transferring a full-length DVD movie in four seconds




9G is full DVD length, right?
9/6,63 is lot less than four...
would say, really close to 1,3s

Well, think they are just approximating. Not many full length movies take up the full 9GB. Some only take about 5GB.

Overall though pretty darn fast.

no.
got me wrong.
if it takes the normal size, around 4-6G, it will be transferred in 1 seconds.
if the maximum available size used (9G) it will take less than 2 seconds.

so what is that estimate all about?

[censored], I think you've got your math wrong :-)

6 Gbit per second is less than 600 MByte per second due to protocol overhead. A rule of thumb is that to transmit 8 raw bits the equivalent of 10 transmission bits are needed.

Thus, assuming 4GByte per DVD movie, you'd have 6-7 seconds for the transmittal.

First off, I feel that J00el is abusing his admin rights on this board by adding his name to the blacklist.

I don't really think the 10 bit word applies here. That is normally just for async serial protocols.

well, to really use my calc and count, say you have 9G disc with full of video data.
taken that media size is not really 9GB but 9 billion bytes and that the media can hold approx only 8,5G it comes to 68 billion bits.
which on turn comes to 10 seconds of transmission time, taken that the wire can transfer that 6,6G/s all the time without slowing down.

and yes, I wasn't thinking that B/b [censored] at first.

well, I'm not.
they all ready had small networks around 1996-98 that transferred 30G per sec just fine.
where are those gone?

Maybe its an every day stuff for you Jooel cause you are deeply involved and you follow the outgoing of technology but if you isolate its meaning it is the third news I belive as "really important", before this one was the first teletransporte atom and before the nanotechnology.

If we make a salad of all this we have "future".
