ATTO is one of the oldest drive benchmarks still being used today and is still very relevant in the SSD world. ATTO measures transfers across a specific volume length. It measures raw transfer rates for both reads and writes and places the data into graphs that can be very easily interpreted. The test was run with the default runs of 0.5KB through 64MB transfer sizes with the total length being 256MB.
Benchmark Results: ATTO Disk Benchmark had the Intel Optane SSD 905P 960GB PCIe NVMe drive reaching speeds of up to 2,717 MB/s read and 2,391 MB/s write in the standard overlapped I/O benchmark. Intel rated this drive as having sequential speeds of up to 2600 MB/s read and 2200 MB/s write and we were able to easily exceed those speeds on out Intel Z370 test platform.
Benchmark Results: Compared to some other SATA III and PCIe NVMe SSDs, the 905P 960GB drive performs well when it comes to sequential read, but a handful of series have now topped 3000 MB/s.
Benchmark Results: The ATTO sequential write performance numbers on the Intel Optane SSD 905P 960GB drive are solid, but are not the fastest available.
CrystalDiskMark is a small benchmark utility for drives and enables rapid measurement of sequential and random read/write speeds. Note that CDM only supports Native Command Queuing (NCQ) with a queue depth of 32 (as noted) and shows the highest score of five runs.
Benchmark Results: The 905P 960GB drive topped out at 2700 MB/s read and 2385 MB/s write in the standard sequential write test that is done at QD32. Random 4K QD1 performance was 212.7 MB/s read and 193.3 MB/s write. The sequential read/write numbers are not that exciting, but the Random 4K performance is impressive.
