About PassMark PerformanceTest 7.0

This Advanced Disk Test, which is part of PerformanceTest, measures the data transfer speed when reading or writing data to one or more disks. The speed that data can be transferred between memory and a hard disk drive is one of a system's most important performance aspects. There are quite a few factors which have a bearing on this speed and the Advanced Disk Drive Test allows the user to vary most of these factors and compare the results.

The test supports any drive that can be mounted under Windows. Including IDE drives, SCSI, RAID, USB key drives, SATA, networked shared drives and external drives.

Users have the ability to test multiple drives at the same time using multiple threads, and specify:

- The size of the test file used. Larger files mean that the system cache has less of an effect on the test types, which use caching (see below).
- The size of the data block used for each read or write request. Larger blocks mean less requests and can lead to an improvement in performance.
- The choice of four access methods - C/C++ API, Win32 API cached / uncached and raw disk access.
- Sequential or random access (seeking plus reading and writing)
- Synchronous and Asynchronous access
- The split between reading and writing

The results of all completed tests may be graphed using our custom graphing components.

PassMark PerformanceTest 7.0's Advanced Disk Test, unlike HD Tune Pro 4.60, generates some awesome graphs right out of the box. It also provides valuable insight in simulating real world performance applications. To make things clear to you, the first graph simulates a database server, followed by a file server, web server, and workstation. Obviously, PassMark PerformanceTest 7.0 uses highly compressible data in most tests that SandForce based SSDs can really take advantage of. However, it also requires high IOPS capabilities for the best score, and as such, the Vector makes an interesting comparison candidate against best scoring drives like the OCZ Vertex 3 Max IOPS 240GB and Kingston HyperX 3K 240GB. I will even throw in the OCZ Vertex 4 256GB to the mix. One thing clear is the OCZ Vector provides incredibly flat and consistent graphs, which is excellent if you are looking for consistent performance. Its average numbers are also among the best. For the first test, it handily beat the SandForce pair, while just a few megabytes behind the Vertex 4. For the second test, it completely destroyed the Vertex 4, but breaks even with the Kingston HyperX 3K and OCZ Vertex 3 Max IOPS. For the third test, the Vector is the winner by a huge margin -- an epic 60MB/s lead over the next closest. While did not beat out the SandForce duo in the last test, it still remained quite a bit ahead of the Vertex 4.
