Samsung 860 PRO SSD Review – 2TB Drive Tested

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 860 PRO 2TB:

Benchmark Results: ATTO showed the Samsung SSD 860 PRO 2TB drive reaching speeds of up to 564 MB/s read and 534 MB/s write in the standard overlapped I/O benchmark. This drive is rated at up to 560 MB/s max sequential read and 530 MB/s max sequential write, so we exceeded both of those scores on our test platform. We did notice that the read score was lower than the write score at 8 KB and this anomaly was repeatable on other platforms. 

Benchmark Results: Compared to some other SATA III SSDs we can quickly see that there isn’t much difference with regards to sequential read/write performance. 

 

 

CrystalDiskMark 6.0.0 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 – Samsung SSD 860 PRO 2TB:

Benchmark Results: The Samsung SSD 860 PTO 2TB drive reached 563MB/s read and 532 MB/s write in the standard sequential write test and Random 4K performance was 44.85 MB/s read and 110.2 MB/s write. 

Let’s look at some other benchmarks!
