Samsung 960 Pro 2TB NVMe M.2 PCIe SSD Review

ATTO & CrystalDiskMark

ATTO v3.05

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 – Samsung SSD 960 Pro 2TB:

Benchmark Results: ATTO showed the Samsung SSD 960 Pro 2TB M.2 NVMe drive topped out at 3,460 MB/s read and 2,1309 MB/s write in the standard overlapped I/O benchmark. These are the highest speeds we have seen from any consumer SSD or HDD.

CrystalDiskMark 5.1.2 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) for the last listed benchmark score. This can skew some results in favor of controllers that also do not support NCQ.

CystalDiskmark – Samsung SSD 960 PRO 2TB:

Benchmark Results: The Samsung SSD 960 Pro 2TB drive reached 2,610 MB/s read and 2,136 MB/s write in the standard sequential write test. The Random 4K performance was 58 MB/s read and 206 MB/s write. At a Queue Depth (QD) of 32 with 1 Thread the sequential performance of the drive shot up to 3,535 MB/s read and 2,139 MB/s write! When we ran the test again set to 0Fill mode and all the scores remained basically the same, but the sequential performance did improve a bit more than we expected.

Samsung rates this particular model at up to 3,500 MB/s read and 2,100 MB/s write when it comes to sequential performance and we were able to surpass those marks in our testing.

Let’s look at some other benchmarks!
