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: On ATTO Disk Benchmark the Silicon Power US70 1TB model is hit speeds of up 5.22 GB/s read and 3.97 GB/s write as our primary boot drive filled to 55% capacity.
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.

Real Performance Preset
Benchmark Results: The SP US70 1TB NVMe SSD finished this benchmark at 5,006 MB/s read and 4,285 MB/s write on CrystalDiskMark 7! The Random 4K performance at QD1 was 60 MB/s read and 213 MB/s write. The official speed ratings on CrystalDiskmark are up to 5,000 MB/s read and 4,200 MB/s wrote, so we are happy with these numbers.
