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. These real world performance simulations finally started to differentiate the Agility 3 and Vertex 3 Max IOPS. With numbers like 135.9MB/s, 404.8MB/s, 356.6MB/s, and 105.5MB/s, respectively, we can finally see why the OCZ Vertex 3 Max IOPS is $100 more in the retail market at press time. The latter posts results of 153.9MB/s, 460.7MB/s, 409.3MB/s, and 89.0MB/s, respectively; and that's quite a significant margin of difference.
With that in mind, the OCZ Agility 3 240GB is by no means slow. Let's pull up our previous SSD reviews with comparable results. In our G.SKILL Phoenix EVO 115GB, an SF-1222 based SSD with 25nm NAND flash, posted numbers of 76.8MB/s, 209.8MB/s, 185.6MB/s, and 76.4MB/s, respectively. In our OCZ Vertex 2 160GB 25nm review, the results turned out to be 75.1MB/s, 217.0MB/s, 197.8MB/s, and 78.3MB/s, respectively. Meanwhile, the original OCZ Vertex 2 60GB posted numbers of 81.1MB/s, 233.1MB/s, 208.7MB/s, and 52.4MB/s, respectively, for your reference.
