Samsung 980 PRO 2TB NVMe SSD Review

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 2TB NVMe SSD reached 5.07 GB/s write and and 6.27 GB/s read at the standard queue depth of 4. 

The two drives with the Phison E18 controller top this chart with ease, but the Samsung 980 PRO series is just behind as is the WD_BLACK SN850.

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.


Peak Performance Preset


Real Performance Preset

Benchmark Results: The Samsung SSD 980 Pro 2TB drive came in with scores of 6754 MB/s read and 5019 MB/s write on CrystalDiskMark 7. The 1TB model is rated at 7000 MB/s read and 5100 MB/s write so we were just below the drives rated speeds. Keep in mind that this is with the Microsoft Windows 10 NVMe driver. The Samsung NVMe driver is said to be not needed for this series. Random 4K performance was also excellent with ~82 MB/s read and ~192 MB/s write on both drives at a queue depth of 1.

Let’s look at some other benchmarks!
