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
- 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.
Our current chart has six SandForce SF-1200 drives on it and we have tested eight to date. When it comes to performance the main difference in speed comes from the firmware used and the chart represents four different firmware versions.
The Inferno arrived with a stock version called MP1, the first Mass Produced firmware for SandForce drives. Other than the OCZ Vertex 2 with its exclusive high 4K IOPS firmware and the Corsair Force which used an early beta firmware with a few bugs ironed out by Corsair engineers to achieve high 4K IOPS, the other firmware versions we tested were beta, pre-release but close enough to test.
When it comes to read speeds across the drives the only real standout on this chart is the Crucial RealSSD C300, the only SATA 6G SSD at this time.
The Patriot Inferno produces an excellent flat performance graph once the initial Windows cache is passed. Looking at our charts, you can see this by how close the maximum and average read speeds are.
When it comes to writing data the same is true for the Patriot Inferno. Here we see the maximum and average speed together in a tight group and they stay that way after the initial 1ms of Windows cache is passed.
If you are currently comparing the RealSSD C300 to the Inferno, this is a good place to point out that the 128GB version of the C300 has a reduced write speed limit when compared to the 256GB C300 we initially looked at right after CES. At this time we are recommending SandForce over the C300 in the 100 to 128GB capacity range / price point.
