CystalDiskMark:īenchmark Results: The Samsung SSD 980 Pro 1TB drive came in with scores of 6753 MB/s read and 4952 MB/s write on CrystalDiskMark 7. 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. CrystalDiskMark 7.0.0 圆4ĬrystalDiskMark is a small benchmark utility for drives and enables rapid measurement of sequential and random read/write speeds. The write speed in ATTO Disk benchmark puts the Samsung SSD 980 Pro at least 1GB/s ahead of the nearest competitor, but at 128KB the read speeds are on par with other PCIe Gen 4.0 SSDs like the Corsair Force MP600 and the Sabrent Rocket PCIe 4.0 drives. The write speeds on both drives peaked at the I/O size of 128KB! The Samsung SSD 980 Pro 500GB topped out at 4.88 GB/s write and and 6.46 GB/s read. ATTO Disk Benchmark:īenchmark Results: On ATTO Disk Benchmark found that the Samsung SSD 980 Pro 1TB NVMe SSD reached 5.11 GB/s write and and 6.31 GB/s read at the standard queue depth of 4. The test was run with the default runs of 0.5KB through 64MB transfer sizes with the total length being 256MB. It measures raw transfer rates for both reads and writes and places the data into graphs that can be very easily interpreted. ATTO measures transfers across a specific volume length. ATTO is one of the oldest drive benchmarks still being used today and is still very relevant in the SSD world.
