Samsung 980 PRO 250GB M.2 SSD

We put the Samsung NVMe M.2 SSD through a detailed test. You can find the test result / test report here:

AS SSD Benchmark

Standard performance test

The standard test was performed with a 5 GB file. A total score of 6542 points was achieved.

AS SSD	Read:	Write:
Seq in megabytes per second	5,278.81 MB/s	2,537.23 MB/s
4K in megabytes per second	76.87 MB/s	172.76 MB/s
4K-64Thrd in megabytes per second	1,884.48 MB/s	2,479.87 MB/s
Access time in milliseconds	0.022 ms	0.125 ms
Score	2489	2906
Total score	6542

Copy performance test

A common everyday scenario is simulated here. Three test folders are created:

• ISO (folder with two large files)
• Program (folder with many small files)
• Game (folder with small and large files)

The three folders are copied using the Windows copy command (cache remains enabled). The real-world test from 02 November 2020 shows performance during simultaneous write and read operations. The lower the duration, the better.

AS SSD Copy Benchmark	Transfer rate:	Duration:
ISO two large files	1,905.38 MB/s	0.56 s
Program typical program folder with many small files	764.90 MB/s	1.84 s
Game a game folder with small and large files	1,413.65 MB/s	0.98 s

Compression performance test

Here, speed is measured depending on how compressible the data is.

CrystalDiskMark Benchmark

Similar to AS SSD, two sequential and two random performance tests are carried out here and the write and read speed (manufacturer specs: 6400 MB/s and 2700 MB/s) the Samsung SSD is measured.

CDM	Read [MB/s]	Write [MB/s]
SEQ1M Q8T1	6,465.43	2,690.93
SEQ1M Q1T1	3,794.56	2,698.61
RND4K Q32T16	2,290.51	2,602.78
RND4K Q1T1	85.19	198.97

HD Tune Pro Benchmark

HD Tune writes a 5 GB file to the Samsung NVMe M.2 SSD. The transfer data of the read speed is displayed graphically. The minimum, maximum and average values are also determined. The measured access time and burst rate are also shown.

ATTO Disk Benchmark

Here, a 256 MB file is written to the Samsung NVMe M.2 SSD multiple times. The I/O block size varies (from 512 bytes to 64 megabytes). The larger the blocks, the faster writing and reading usually becomes.

SSD-Z Benchmark

Similar to HD Tune, a 500 MB file is written to the Samsung NVMe M.2 SSD here. The transfer data is displayed. The more consistent the line, the better. Unfortunately, the tool no longer works correctly from around 4,000 MB/s and no line is displayed (and sometimes incorrect min/max data is shown).

The benchmark test review was performed on 02 November 2020.
