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.

Transferring files from one partition of the drive to another, the simulated test inside AS SSD left us with a desire for more performance when comparing the 5K4000 to the WD Red. When you overlook the Red and 10K RPM Raptor 1TB, the 5K4000 does a good job. Just knowing that the Red does a better job in this test that is very important for storage drives is enough to give us some second thoughts, though. The Red isn't offered in 4TB either, a big plus for the HGST 5K4000.
