About PassMark PerformanceTest 8.0

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.

Finally, we get to a benchmark that generates some nice graphs right out of the box! PassMark PerformanceTest 8.0's Advanced Disk Test provides valuable insight in simulating more real world performance applications. The first graph simulates a database server, followed by a file server, web server, and workstation, in that order. PassMark PerformanceTest 8.0 uses highly compressible data in most tests, so once again, SandForce based SSDs will really take advantage of this. However, it also requires high IOPS capabilities for the best score. While the OCZ ARC 100 240GB does not provide the highest of IOPS, it will be interesting to see how it handles actual day-to-day situations. It is good to see generally flat graphs across all of the results, as this demonstrates consistent behavior. Unfortunately, since PerformanceTest 8.0 was updated more recently, we cannot compare it to past drives of similar audience target, as they were tested with Performance Test 7.0. However, looking at some recent drives provide some interesting results. For example, in the database test, the OCZ ARC 100 pulls similar numbers to the SanDisk Extreme PRO 480GB. It is even better than the Extreme PRO for the file server test. Otherwise, the OCZ Vertex 460 and Vector 150 ran circles around the little brother ARC 100. What a bunch of bullies, haha.
