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
To make things a little more interesting, we ran AS SSD's copy benchmark two ways. Here we see the HDD in the ioSafe Portable Rugged connected to a USB 3.0 port. The performance is in line with other portable devices that use similar HDDs over USB 3.0.
In this test we removed the Seagate drive from the Rugged Portable and connected it to the motherboards native SATA interface. Ideally the two benchmark runs should be very close to each other, but as you can see, the Rugged Portable's USB 3.0 to SATA bridge slows the drive down a bit.
