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, but the OCZ Vertex 4 256GB has much higher IOPS capabilities than any SF-2281 drives we have ever tested. Compared against the OCZ Vertex 3 Max IOPS 240GB, the Vertex 4 256GB posted better numbers than its predecessor only in the database server simulation. Once again, SandForce drives have an inherent advantage over other drives due to the way the controller is designed, but this may not always be indicative of an SSD's true performance with different controllers.
