Next goes the read operation. Here’s the table:

And the diagrams:

The Hitachi HTS548040M9AT00 reads the Install pattern at the highest speed. The other drive from Hitachi, the DK23FB model, keeps up this family tradition, being quite good in this test, too.

The advantage of the Hitachi HTS548040M9AT00 is even more conspicuous in the ISO pattern. The Toshiba 4026GAX offered some competition to the Hitachi duo, leaving behind the drives from Fujitsu, Samsung and Seagate.

The drives from Hitachi couldn’t keep their leadership, yielding it to the Fujitsu MHT2040AH. Another Fujitsu, the MHT2040BH model, took the third place.

The Hitachi team is again the best when reading files of the Programs and Windows patterns.
