WD Blue SN500 SSD - SANDRA And ATTO Benchmarks

Next we used SiSoft SANDRA, the the System ANalyzer, Diagnostic and Reporting Assistant for some quick tests. Here, we used the Physical Disk test suite and provide the results from our comparison SSDs. The benchmarks were run on clean drives that lacked any partitions. Read and write performance metrics are detailed below.

The WD Blue SN500's write speeds barely edged out the Intel SSD 760P, but its read performance trails the pack.
ATTO Disk Benchmark

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 64MB 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.

The WD SN500 Blue generally trailed the Crucial P1 here, until hitting the higher transfer sizes, where the P1's performance dropped off.
