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.

PassMark PerformanceTest 8.0'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 8.0 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 SanDisk Extreme PRO 480GB is an interesting candidate. One thing clear is the Extreme PRO provides incredibly flat graphs, which is excellent if you are looking for strong consistent performance. Overall, this SATA solid state drive is really good, even if it does not have the inherent SandForce advantage. If we look at the OCZ Vector 150 240GB, one of the best drives in the segment (Which is actually Indilinx Barefoot 3, by the way), delivered 142.09MB/s, 426.34MB/s, 475.82MB/s, and 73.10MB/s, respectively. The Extreme PRO 480GB came in at 101.31MB/s, 297.43MB/s, 481.05MB/s, and 81.77MB/s in the same corresponding order. The Vector 150 is better in the database server and file server tests by a pretty good margin, but the Extreme PRO wins back in the web server and workstation simulations. That said, it is still a bump up from the SanDisk Extreme II 240GB at 101.77MB/s, 279.75MB/s, 476.35MB/s, and 75.36MB/s, respectively.
