You can compute the maximum possible sequential I/O rate. It's easy: Look at how many blocks are in one track and how long it takes the disk to make one revolution (at 7200 RPM) then you will know how many bits per second fly under the read/write head. This places an upper bound on the sustained I/O rate.
Generally the XFS file systems gives fastest result.
To make faster read operations, make a separate partition on your drive, possibly at the beginning of the drive (as the beginning of the drive is faster)
