WinBench 99

Here is the data-transfer diagram for the Hitachi HTS721010G9AT00 drive:

The speed is over 50MB/s at the beginning, the shape of the graph betraying no defects.

We will first check the drives in FAT32 by creating one 32GB partition on them. It is High-End Disk WinMark that is the more important of the two WinBench scores.

So, the Hitachi HTS721010G9AT00 beats its opponents, including its own Serial ATA version. It has the highest High-End Disk WinMark as well as the highest Business Disk WinMark score. The difference in the performance of the Hitachi drives with Parallel ATA and Serial ATA interfaces is too big to be disregarded as a measurement error.

But what if we use NTFS?

The Hitachi HTS721010G9AT00 is again victorious. Its High-End Disk WinMark and Business Disk WinMark scores are both higher than its opponents’.

The last diagram in this section shows the read speed at the beginning and end of each drive. Note that both the drives from Hitachi have almost identical speeds, and they are both faster than the drives from Seagate.
