We analyze, within a dipole model, the final, inclusive HERA DIS cross section data in the low x region, using fully correlated errors. We show that these highest precision data are very well described within the dipole model framework starting from Q(2) values of 3.5 GeV2 to the highest values of Q(2) = 250 GeV2. To analyze the saturation effects we evaluated the data including also the very low 0.35 < Q(2) GeV2 region. The fits including this region show a preference of the saturation ansatz.
