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.
The deltas separating the drives were relatively small, but the Samsung SSD 850 drives technically led the pack in our SiSoft SANDRA testing. The Vector 180 was right there alongside them, however.
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.
We witnessed a few dips in performance with the Vector 180 according to the ATTO Disk Benchmark, which were repeatable on our test system. With the vast majority of block sizes, however, the Vector 180’s performance was solid.
