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 write speed difference of the 60GB capacity Vertex 2 E does show up in the copy tests. We have seen SandForce drives lost out to some other SSDs in these tests because of the way SandForce drives handle compressed data. In some ways the SF-1200's strongest feature is also its biggest detractor, but only in some situations where data is already compressed.
For the last few months I have spent a great deal of time pondering over just how much compressed data is kept on a smaller drive. With smaller drives you will keep less music, movies and compressed files since the space is just not available to keep much of that data to begin with.
