Intel Optane SSD 800P Review: A Speedy M.2 Solid State Drive With 3D XPoint For The Masses
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 SSD 800P series drives trail only the higher-end Optane SSD 900P series drive. Once the transfer sizes increase, however, the Optane SSD 800P series drives attain their rated 1.4GB/s / 600MB/s read and write speeds, before tapering off with the largest transfer sizes. Once again, sequential transfers likes these aren't the 800P's strong suite, and the drives end up trailing for the most part in ATTO.
