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.

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 the OCZ Vertex 2 running slightly behind the Crucial RealSSD C300 128GB in the Program test, but once we start mixing compressed data in we see a 20MB/s divide in the Game test and a large 60MB/s lead going to the C300 in the ISO test.


Once again the capacity of the drives comes into play here. At 100 / 120 / 128GB you are not going to be keeping a large amount of data on the OS boot drive to transfer around. The larger capacity size is a different story. We will get into more details on this in the conclusion.
