The test system used in this review is equipped with an AMD Ryzen 3 3100 CPU, MSI B550 GAMING PLUS motherboard, 16GB (8GB x 2) of Crucial Ballistix 3200 MHz DDR4 memory, Crucial P5 1TB SSD and a GIGABYTE GeForce GTX 1060 WINDFORCE OC 6G graphics card. For the operating system, I used the latest version of Windows 10 Pro.
To test the performance of Samsung's 980 PRO SSD, I ran a series of benchmarks using CrystalDiskMark, HD Tach RW, ATTO Disk Benchmark, AS SSD, HD Tune Pro, Anvil's Storage Utilities, Iometer and PCMark. For comparison, I've also included test results from the ADATA XPG GAMMIX S70, Sabrent Rocket 4 Plus, WD_BLACK SN850, Silicon Power US70, ADATA XPG GAMMIX S50 Lite, Silicon-Power UD70, Crucial P2, SK hynix Gold P31, Crucial P5, ADATA SWORDFISH, ADATA FALCON, Lexar NM610, Silicon Power P34A60, Patriot P300, Plextor M9PG Plus, Plextor M9PY Plus, ADATA XPG SX6000 Pro, Western Digital WD_BLACK SN750, Samsung 970 EVO Plus, ADATA XPG SX8200 Pro, Crucial P1, ADATA XPG SX8200, Western Digital WD_BLACK NVMe, Samsung 970 EVO, Samsung 970 PRO, Plextor M9Pe, Plextor M8Se, Patriot Hellfire, ADATA XPG SX8000, Samsung 960 PRO, Toshiba OCZ RD400, Samsung 950 PRO, Samsung 870 EVO, Samsung 870 QVO, Silicon Power PC60, SK hynix Gold S31, ADATA Ultimate SU750, Samsung 860 QVO, Samsung 860 PRO and Crucial MX500.
As I mentioned earlier, the 980 PRO uses Samsung's Elpis controller chip. Looking at the screenshot above, you can see that it performs equally well with both incompressible (0%) and compressible (100%) data.
CrystalDiskMark 7.0.0:
First, I ran a few quick tests using CrystalDiskMark. This benchmark measures the performance of a storage device by testing its sequential and random read and write speeds. For this test, we're using the peak and real world profiles.
According to Samsung, the 2TB version of the 980 PRO is capable of reading at 7,000 MB/s and writing at 5,100 MB/s. Looking at the screenshot above, you can see that while the drive performed quite well, it came up a bit short of these numbers in CrystalDiskMark's sequential read and write tests.
As you'd expect, the 980 PRO wasn't nearly as fast when tested with the "real world" profile which uses a single thread and a much lower queue depth. Nevertheless, it was still able to read at 4,064 MB/s and write at more than 4,200 MB/s.
HD Tach RW 3.0.4.0:
Next, I used HD Tach to test the 980 PRO's read, write and burst speeds as well as its random access time and CPU usage.
Looking at the screenshot above, you can see that the 980 PRO had average read and write speeds of 2160.9 MB/s and 1738.6 MB/s respectively, as well as a burst speed of 2658.7 MB/s. The screenshot also shows the transition from TurboWrite to what Samsung calls "After TurboWrite" speeds. The 980 PRO starts writing at about 2000 MB/s and then drops to about 1600 MB/s when the consecutive write operation exceeds the size of the SLC buffer.
ATTO Disk Benchmark 4.01:
I also used ATTO Disk Benchmark to test the 980 PRO's sequential read and write speeds. The tests are run using blocks ranging in size from 512B to 64 MB and the total length set to 256MB.
 Samsung 980 PRO 2TB |
 Sabrent Rocket 4 Plus 1TB |
When tested with ATTO, the 980 PRO's read speeds topped out at about 6.38 GB/s and its write speeds at 4.69 GB/s.
