HD Tune – Sequential reading test
I present the graph below for comparison with other recently tested drives.
A good performance from the ADATA SP900.
ATTO disk benchmark
ATTO has become a standard tool for measuring the data throughput of HDD and SSD. It measures the performance of reading and writing, using different file sizes and block sizes.
As expected, ATTO was able to show the maximum performance that the ADATA SP900 can achieve.
Crystal Disk Mark is quite a handy benchmarking application, as it focuses on the file sizes that can cause a problem on a system drive.
The default setting on CrystalDiskMark is to use random data, and that gives a more realistic view on the performance of any drive. The overall performance of the ADATA SP900 is good,
AS SSD Benchmark
AS SSD benchmark is a benchmarking tool specifically designed to test SSDs. The application tests sequential reading and writing performance, 4K random reading and writing performance.
AS SSD benchmark also tests 4K threaded performance. This is very exciting, as this test is the first available test that I am aware of, that simulates how a PC operating system actually works. A modern PC and OS, such as Windows Vista/7 does not just run a single thread at a time, it runs many threads. The AS SSD benchmark "4K 64Thrd" tests run 64 threads simultaneously throughout the test. If this result is good, then you can be pretty sure the drive will perform extremely well as a system drive.
After the tests complete, AS SSD benchmark derives a total score for the drive being tested. This is based on all aspects of the test results, and gives an indication of how the drive is performing overall.
Now let’s look at the results for the ADATA SP900 128GB SSD in the form of a screenshot. All our other comparison drives’ results are presented in the form of a graph.
In this test, the ADATA SP900 SSD is in the middle, with an average score of 446MB/s.
The ADATA SP900 SSD has good overall performance..
Let's head to the next page for our IOMeter test results.....
