Man page on split:
"NAME
       split - split a file into pieces
 
SYNOPSIS
       split [OPTION] [INPUT [PREFIX]]
 
DESCRIPTION
       Output  fixed-size  pieces of INPUT to PREFIXaa, PREFIXab, ...; 
default
       PREFIX is `x'.  With no INPUT, or when INPUT is -, read standard 
input.
 
"

So maybe ...
dd if=/dev/sdb | split -b 640m
for i in `ls x??`
do
    cat $i | tee /path_1/$i /path_2/$i_2 2>&1 /dev/null
done
...maybe?
