AS SSD 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.

To be honest this test really threw me for a loop. The Caviar Green didn't perform nearly as well as I expected it would. Most people aren't ever going to use the Caviar Green as a boot drive. Let's just cut the marketing stuff and get down to it; most 2 and 3TB drives will be used to store data for the time being. That makes this test very important. With that in mind, we really have to wonder what the heck is going on with this drive.


The above retest was performed using the GIGABYTE X58A-UD7's on board Marvell controller. As you can see, the Western Digital Caviar Green 3TB received a significant boost in performance even though the Marvell controller was also running the operating system drive.

Even with the faster configuration, the Caviar Green 3TB was slower than the other two drives, but the gap was reduced.
