[Dclug] Question about Speed: data transmission vs write-to-disk

I hope this is not considered OT; it is somewhat theoretical.
Data, over very fast trunk routers, comes at one very fast, what
with frequence of light carrier waves, and ever-increasing modulation
technology. If the output of some such pipe has to be written
to disk, can the writing to disk keep up? Will it always be
My thought: RAID has, in my hearing, always been discussed as a
security/safety measure, so that data can be recovered even in case
of a disk crash. But are writes to a RAID system, by say a multi-processor
machine, faster than straight writes to a single disk?
Any thoughts much appreciated; extra credit for detailed knowledge!<G>
