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 gained popularity amongst reviewers. It is now considered a must have application for storage device testing.
Also like the other capacity sizes, the SanDisk Extreme II makes its presence known on the charts right away. Extreme II 480GB pushed the sequential bar a little higher. I didn't really expect to see anything knock 840 Pro off the top step with SATA III since we're butting up against the real-world limits of SATA 6Gb, but Extreme II managed to raise the bar.
When writing sequential data, Vector is a little faster at peak, but the Extreme II has a slightly higher average write speed with this type of data.
HD Tach - Sequential Write Performance after Random Writes
After hitting the Extreme II 480GB with a realistic amount of random writes, we measured the sequential read and write performance again. Extreme II only drops below 200MB/s once in this test.
