"its" linearly faster for reading ... but also linearly slower for writing
:-)
"it" is the proper raid config ...
if you only write once and read it back a gazillion times like google,
than it'd make sense to use stripping

stripping by itself does NOT allow you to read data 2x as faster
sripping ( raid0 ) makes two 80GB look like one bigger 160GB disks
( if the data is only written once, you probably can't read all data
( 2x faster across 2 different disks ..
mirroring ( raid1 ) plus stripping across 2 raid1 does allow you
read 2x faster ... but you lose 1/2 of your disks to duplicate
data ( "mirrors" )
what you'd want is raid01 or raid10 ( slightly different )
more fun stuff ( raid differences )
