Intel Optane SSD 905P Review: Seriously Fast Storage For Enthusiasts
Intel Optane SSD 905P: SANDRA And ATTO Benchmarks
Next we ran SiSoft SANDRA 2017, 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 clean drives that lacked any partions. Read and write performance metrics are detailed below.

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.
With the smallest transfer sizes (4K and below), the Intel Optane drives lead the pack. The 905P (and the 900P) specifically maintain that lead until about the 32K mark, where their top-end sequential transfer speeds are hit and they ultimately end up trailing the faster, NAND-based drives.
