SANDRA and ATTO Disk Benchmarks
Next we ran SiSoft SANDRA 2014, the the System ANalyzer, Diagnostic and Reporting Assistant. Here, we used the File System test suite and provide the results from our comparison SSDs. The benchmarks were run on fully formatted drives, with software RAID 0 configured on the DC P3608. Read and write performance metrics are detailed below.
The Intel SSD DC P3608 nearly doubled the performance of the P3700 series drive here in the read test, and offered up 2GB/s (on average) or write bandwidth, which also led 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 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 Intel SSD DC P3608 doesn't hit its stride until about the 8K transfer size mark in the Write test and 128K mark in the Read test. Before those points, the drive trails the others we tested, but really pulls away--especially in reads--with larger transfer sizes.
