Samsung SSD 845DC EVO Solid State Drive Review
SANDRA and ATTO Disk Benchmark
Next we ran SiSoft SANDRA 2014, the the System ANalyzer, Diagnostic and Reporting Assistant. Here, we used the Physical Disk test suite and provide the results from our comparison SSDs. The benchmarks were run on unformatted drives and read and write performance metrics are detailed below.
Read performance was very good on both of the Samsung SSD 845DC EVO drives we tested. The 960GB drive also put up strong write numbers, though the 240GB couldn't keep up obviously.
ATTO is another "quick and dirty" type of disk benchmark that measures transfer speeds across a specific volume length. It measures raw transfer rates for both reads and writes and graphs them out in an easily interpreted chart. We chose .5kb through 8192kb transfer sizes and a queue depth of 6 over a total max volume length of 256MB. ATTO's workloads are sequential in nature and measure raw bandwidth, rather than I/O response time, access latency, etc.
Once again we see strong read performance from the Samsung SSD 845DC EVO drives. Writes were also very competitive across the entire range of transfer sizes.
