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
The one area that we criticize SandForce controlled drives in is in how they handle compressed data. Ironically the controller's ability to compress data is also one of the reasons why they are so fast and should have a longer lifespan when compared to other products on the market.
In the AS SSD File Copy Test we see that moving data from one area of the drive to another has 100GB Patriot Inferno running slightly behind the Crucial RealSSD C300 128GB in the Program test, but the C300 does pull further away in the other tests. Most users move data around on their HDD, but not so much that it negates the gains of typical Windows uses like application loading.
