CrystalDiskMark is designed to quickly test the performance of your hard drives. Currently, the program allows to measure sequential and random read/write speeds.
Anvil's Storage Utilities
The Standard Storage Benchmark performs a series of tests, you can run the full test or just the read or the write test or you can run a single test like i.e. 4K QD16.
The synthetic tests to determine the sequential and random read and write performance of the SSD. These tests are carried out without using the operating system caches. In Seq-test measures the program how long it takes to read a full 1 GB of file to write respectively. In the 4K test the read and write performance for random 4K blocks is determined. The 4K-64-THRD-test corresponds to the 4K procedure except that here distributes the read and write operations on 64 threads. This test should be SSDs with Native Command Queuing (NCQ) differences between the IDE operation mode where NCQ is not supported, and represent the AHCI mode. The additional compression test can measure the performance of the SSD as a function of compressibility of the data. This is especially the controllers that are used to increase the performance and life of the cell compression is important.
