SQUID itself won't benefit of multi CPU configuration, but the rest of OS
and diskd/aufs spool (using threads or different processes) will.

Where did you get this? Your speed will be smaller when using RAID0, and
when you loose one of disks, you will loose whole cache with RAID0, instead
of just part of it.

So, please tell me who provided you the informations that RAID0 (HS or SW)
is better?

It doesn't need to be separate box, if the CPU's are enough. If you have 2
CPUs in squid machine, you'll get one of them used only a bit, so you can
put DG onto the same machine, if the CPU is fast enough and you have enough
of memory.
