How high can you go by mirroring or striping 2, 3, 4 harddrives?
mirroring - the same, just with 2 processes reading both can get the
bandwidth. make sure you use -s high enough (like 1048576) doing

So if I will put 6 hard drives with stripping each of them is 85MB/s (in the
beginning sectors) I will get 6X85MB/s=4.08Gb/s?
Is it reasonable to expect this kind of speed? Something tells me that there
will be some other

You are limited by the bus speed and controller buffer speed
(whichever is slower).
My motherboard has PCI Express v2.0, that is 500MB/s limitation.
Also it has HD/RAID controller Intel ICH10R

Highly unscientific measurement here, but I seem to be getting a max of
~160 MB/s by striping two Seagate 500Gb drives.
