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 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. One thing clear is the Toshiba OCZ TL100 240GB provided flat graphs, which is great if you are looking for consistent performance.
Overall, this SATA solid state drive's performance was quite a bit slower compared to its peers. With results of 42.17MB/s, 313.40MB/s, 364.40MB/s, and 78.02MB/s, respectively, this was mostly behind all of its competitors, with the exception of the last test. To put these numbers in perspective, the OCZ Trion 100 480GB was at speeds of 98.78MB/s, 336.53MB/s, 402.22MB/s, and 70.08MB/s. Similarly, the OCZ Trion 150 480GB produced speeds of 106.41MB/s, 343.49MB/s, 493.98MB/s, and 70.19MB/s. Moving on, the TLC NAND SanDisk Ultra II 240GB posted results of 105.59MB/s, 345.68MB/s, 433.65MB/s, and 88.68MB/s, respectively. The budget Crucial BX100 500GB came in at 120.63MB/s, 363.14MB/s, 401.65MB/s, and 67.86MB/s, respectively. Finally, the most recent budget drive of interest, the Kingston SSDNow UV400 480GB gave results of 82.56MB/s, 340.70MB/s, 397.98MB/s, 67.05MB/s, in the corresponding order. At the time of the UV400 review, we already considered its numbers to be not very competitive. Whether it was the lack of DRAM or another reason, the Toshiba OCZ TL100 240GB results are quite disappointing. In case you are curious, 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), it delivered 142.09MB/s, 426.34MB/s, 475.82MB/s, and 73.10MB/s, respectively.
