About PassMark PerformanceTest 9.0

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 9.0's Advanced Disk Test generates some superb 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 9.0 uses highly compressible data in most tests some controllers can really take advantage of. However, it also requires high IOPS capabilities for the best score. In the past, Marvell and Indilinx based drives perform pretty well in this test.

Overall, the Gigabyte UD PRO 256GB's performance was acceptable, but fell behind the competition. With results of 100.34MB/s, 307.69MB/s, 447.29MB/s, and 65.47MB/s, the scores were average at best. For comparison, these marks were traded between the Kingston UV500 240GB SATA, which gave marks of 76.80MB/s, 343.02MB/s, 422.85MB/s, 80.60MB/s. The UV400's numbers were 82.56MB/s, 340.70MB/s, 397.98MB/s, and 67.05MB/s. The Crucial MX500 500GB bested all of the UD PRO's marks with results of 155.76MB/s, 434.76MB/s, 488.07MB/s, and 73.11MB/s, in the same corresponding order. Meanwhile, the Crucial BX300 240GB was class-leading at 115.56MB/s, 432.77MB/s, 493.12MB/s, and 93.13 MB/s, respectively.
