HD Tune Pro
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
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.
There was no question about the SoloPRO being able to outperform the first generation Solo since the interface has so much more available bandwidth. Here we see exactly how much faster eSATA is over USB 2.0.
The same is true with the write test across the disk. On average we see a three times speed increase with eSATA, but it should be closer to four times faster.
Remember back when I told you that most motherboards implementation of eSATA had a few drawbacks? - In this write performance graph we see a large area where the write speed is static from left to right. A proper graph will show the hard drive slowly winding down like it does at the end of the graph on the right side. This is caused by the eSATA bridge chip that most motherboard companies are using; generally a JMicron chip, AKA the kings of subpar performance.
If you want to get the maximum performance out of your ioSafe SoloPRO, you want to spend three Dollars and get an adapter bracket. I'm actually kind of surprised ioSafe didn't include one with the SoloPRO.
