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 870 EVO 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 8. For comparison, I've also included test results from the Samsung 870 QVO, SK hynix Gold S31, ADATA Ultimate SU750, Samsung 860 QVO, Samsung 860 PRO, Crucial MX500, Plextor M8V, Crucial BX300, ADATA Ultimate SU900, Plextor S3C, Toshiba OCZ VX500, ADATA Ultimate SU800, Plextor S2C, Crucial MX300, Plextor M7V, PNY CS1311, OCZ Trion 150, PNY CS2211, Plextor M6V, Crucial BX200, OCZ Trion 100, Kingston HyperX Savage, Crucial MX200, OCZ Vector 180, Kingston BX100, Samsung 850 EVO M.2, Samsung 850 EVO mSATA, AMD Radeon R7, Silicon Power Slim S80, Samsung SSD 850 EVO, OCZ ARC 100, SanDisk Ultra II, Crucial MX100, SanDisk Extreme Pro and Samsung SSD 850 PRO.
As I mentioned earlier, the 870 EVO uses Samsung's MKX 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 1TB version of the 870 EVO is capable of reading at 560 MB/s and writing at 530 MB/s. As you can see, the drive had no problems reaching these speeds in CrystalDiskMark's sequential read and write tests.
As you'd expect, the 870 EVO wasn't 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 and write at more than 523 MB/s.
HD Tach RW 3.0.4.0:
Next, I used HD Tach to test the 870 EVO's read, write and burst speeds as well as its seek times and CPU usage.
Looking at the screenshot above, you can see that the 870 EVO had average read and write speeds of 468.1 MB/s and 447.7 MB/s respectively, as well as a burst speed of 495.9 MB/s.
ATTO Disk Benchmark 4.01:
I also used ATTO Disk Benchmark to test the 870 EVO'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.
When tested with ATTO, the 870 EVO's read speeds topped out at about 538 MB/s and its write speeds at 512 MB/s.
