with linear read it will get speed of one drive, linear write - a bit
slower (2 writes must be done but in parallel).
BUT:
with 100 processes reading different things from it it could be up to 6
times faster (actually bit less as it will never get spread evenly) than
single drive. writes near 3 times faster.
