AS determines the performance of Solid State Drives (SSD). The tool contains four synthetic as well as three practice tests. The synthetic tests are to determine the sequential and random read and write performance of the SSD. These tests are carried out without the use of the operating system caches.


In all synthetic tests the test file size is 1GB. AS can also determine the access time of the SSD, the access of which the drive is determined to read through the entire capacity of the SSD (Full Stroke). The write access test is only to be met with a 1 GB big test file. At the end of the tests three values for the read and write as well as the overall performance will be issued. In addition to the calculated values which are shown in MB/s, they are also represented in IO per seconds (IOPS).


Note: AS SSD is a great benchmark for many tests, but since Crystal Disk Mark covers a broader range of 4K tests and HD Tune Pro covering sequential speeds, we will only use the Copy Benchmark from AS SSD.


- Copy Benchmark




There is more to computing than just your day-to-day tasks even though they are very important. We have a philosophy for the copy test that is fairly unique in the industry. The larger your drive the more optional data you'll keep in it. With smaller drives, especially those under 100GB, you don't have a lot of space for music, movies or images after you install the OS, Office and essential boot drive items. That means the larger the drive the more you'll transfers files to and from your drive so this test has a higher degree of importance with larger drives.


Looking at the chart we see that the Plextor M3 Pro 256GB is a brute when transferring data.
