This might be on accident, or as part of a deliberate PR strategy to obfuscate the real world performance behind a 'holy' unified metric. SSDs in general have been getting more complex, so there are more ways for benchmarks to end up being misleading or unrealistic. A lot has changed in the SSD market over the past several years, and our SSD testing methods need to change in response to those trends. The results of all completed tests may be graphed using our custom graphing components.The last major update to our consumer SSD benchmark suite was introduced in 2017.

Sequential or random access (seeking plus reading and writing).

The choice of four access methods - C/C++ API, Win32 API cached / uncached and raw disk access.

Larger blocks mean less requests and can lead to an improvement in performance.

The size of the data block used for each read or write request.

Larger files mean that the system cache has less of an effect on the test types, which use caching (see below). Users have the ability to test multiple drives at the same time using multiple threads, and specify:

Including IDE drives, SCSI, RAID, USB key drives, SATA, networked shared drives and external drives.

The test supports any drive that can be mounted under Windows. 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 speed that data can be transferred between memory and a hard disk drive is one of a system's most important performance aspects. This Advanced Disk Test, which is part of PerformanceTest, measures the data transfer speed when reading or writing data to one or more disks. Advanced Disk Test - Hard drive benchmark
