BENCHMARK PROTOCOL AND THE TEST BENCH
In testing, our main objective is to obtain results as pure and as accurate as possible and we want to ensure that no anomalies slip through. Simply put, we want to provide you with the absolute best results the tested hardware can provide. Repetition in testing is standard and, if necessary, we may conduct specific tests in Windows 7 safe mode to ensure the OS has little to no influence on the end result.
In order to validate and confirm our findings, testing is supported by industry accepted benchmark programs. All results are displayed through capture of the actual benchmark for better understanding of the testing process by the reader.
Software used for testing by The SSD Review consists of ATTO Disk Benchmark, Crystal DiskMark, AS SSD, Anvil Storage Utilities, HDTune along with FutureMark PCMark Vantage. We are even going to throw in a bit of a bonus with Samsung Magician performance testing.
All do a great job of showing us the numbers that we want to see, or dont want to see in some cases, while PCMark Vantage x64 is an excellent program which recreates tests that mimic the average users activity, all the while providing a medium to measure each.
Benchmark software used by The SSD Review can be obtained by clicking on the title of each application as all may be downloaded without cost to the consumer.
ATTO Disk Benchmark is perhaps one of the oldest benchmarks going and is definitely the main staple for manufacturer performance specifications. ATTO uses RAW or compressible data and, for our benchmarks, we use a set length of 256mb and test both the read and write performance of various transfer sizes ranging from 0.5 to 8192kb. Manufacturers prefer this method of testing as it deals with raw (compressible) data rather than random (includes incompressible data) which, although more realistic, results in lower performance results.
Crystal Disk Benchmark is used to measure read and write performance through sampling of raw (0/1 Fill/compressible) or random data which is, for the most part, incompressible. Samsung SSDs have similar results regardless of the sample data and our test below shows the worst case test scenario with random or ‘highly incompressible’ data being transferred during the test.
