SANDRA and ATTO Disk Benchmark
Next we ran SiSoft SANDRA 2014, the the System ANalyzer, Diagnostic and Reporting Assistant. First, 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. In the File System test, however, the drives were partitioned and formatted.
The Intel SSD DC P3700 outpaced all of the other drives by a wide margin in the read test, and while it didn't lead in the write test, it finished very close to the top.
In the File System benchmark, the Intel SSD DC P3700 once again dominated the rest of the pack.
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.
It's not until transfer sizes exceed the 256K mark in the ATTO read benchmark that the Intel SSD DC P3700 can really stretch its legs, but when it does, it's significantly faster than all other drives we have tested. In the write test, however, the Intel SSD DC P3700 shoots into the lead at 4K and stays there throughout.
