Samsung SSD 980 Pro Review – 1TB & 500GB Capacities Benchmarked

ATTO & CrystalDiskMark

ATTO v4.01.0f1

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.

ATTO Disk Benchmark:

Benchmark 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 Samsung SSD 980 Pro 500GB topped out at 4.88 GB/s write and and 6.46 GB/s read. The write speeds on both drives peaked at the I/O size of 128KB!

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.

CrystalDiskMark 7.0.0 x64

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.

CystalDiskMark:

Peak Performance Preset

Real Performance Preset

Benchmark 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. The smaller SSD 980 Pro 500GB model was able to finish the benchmark with seeds of 6784 MB/s read and 4874 MB/s write! The 1TB model is rated at 7000 MB/s read and 5000 MB/s write so we were just below the drives rated speeds. Random 4K performance was also excellent with ~85 MB/s read and ~192 MB/s write on both drives at a queue depth of 1.
