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 SSD 660p 1TB PCIe NVMe drive reaching speeds of up to 1,931 MB/s read and 1,819 MB/s write in the standard overlapped I/O benchmark. Intel rated this drive as having sequential speeds of up to 1800 MB/s read and 1800 MB/s write, so we are able to perform better than that on our Intel Z370 test platform.
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 660p 1TB drive topped out at 1934 MB/s read and 1814 MB/s write in the standard sequential write test that is done at QD32. Random 4K QD1 performance was 57.8 MB/s read and 147.0 MB/s write. These are solid scores for a value drive!
