HD Tune is a Hard Disk utility which has the following functions:

- Benchmark: measures the performance
- Info: shows detailed information
- Health: checks the health status by using SMART
- Error Scan: scans the surface for errors
- Temperature display

HD Tune Pro gives us accurate read, write and access time results and for the last couple of years has been gaining popularity amongst reviewers. It is now considered a must have application for storage device testing.

Read Tests

The group of performance numbers on the bottom shows us what the drive is capable of running at. Ideally we would see similar results for the two sets of numbers on the top, but it doesn't look like that is going to happen today.

When it really comes down to it, both USB 3.0 cards limit our maximum speeds and on the performance graph it was very obvious since we just saw a straight line that held its ground over half of the benchmark.

The Vantec USB 3.0 PCIe Host Card is limited more than the ASUS U3S6 by more than 20MB/s at peak and around 16MB/s on average.

Write Tests

The write speeds of the Vantec USB 3.0 PCIe Host Card are also severely limited. Here we see a 20 to 25 MB/s difference between the ASUS U3S6 and the Vantec card.
