Funny, we just had this argument on the Google cloud computing list.
Scalable and fast are not synonyms.

Faster disks and faster computer raises the amount of work you can do on
a single computer, but still doesn't scale. When the cycles are gone,
the cycles are gone.

Another way to look at the problem is this: If you have 100 GB worth of
memory to put on a network, does it make sense to structure it as a disk
on a single computer or spread it around as a big distributed L2 cache?
