PERFORMANCE AND HEAT DISSIPATION
The Samsung SSD SM825 speaks of ‘sustained performance’ at 260MB/s read and 235MB/s write with 35,000 IOPS read and 10,000 IOPS write. The key to this statement is ‘sustained performance’ where these values may be lower than we might see in a consumer drive but firmware is set so this same performance will be seen on the last day of service just as it was on its introduction and through any number of conditions. This type of reliability just isn’t possible in most drives today.
Power consumption for the SM825 is listed at 1.3W idle and 1.8W active and there are thermal pads on either side of the PCB that allow for the heat to be channeled to the exterior metal case where it dissipates through data center cooling. Last but not least, the SM825 has full AES-256 bit encryption and an amazing 2 million hours MTBF.
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, and Anvil Storage Utilities. We would normally use PCMark Vantage HDD Suite testing in our benchmark comparisons as it is based on eight typical user scenarios, however, the fact that it was based on this gave us just reason to exclude it in this review.
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.
