Intel SSD DC P3520 Series NVMe PCIe Enterprise Solid State Drive Review
SANDRA and ATTO Disk Benchmarks
Next we ran SiSoft SANDRA, 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 partitions that spanned the entire capacity. Read and write performance metrics are detailed below.
The Intel SSD DC P3520 2TB drive hit numbers exactly in-line with Intel's sequential read and write performance ratings here -- 1.7GB/s average reads and 1.35GB/s average writes.
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 P3520 2TB drive performed relatively well with all of the transfer sizes in the ATTO's write test, and trailed the higher-end P3700 series drive by only a small margin. In the read test, the P3520 didn't fare as well with smaller transfer sizes, but performance shot back up once it got past the 1MB mark.
