Random 4K performance was also excellent with ~82 MB/s read and ~192 MB/s write on both drives at a queue depth of 1. There are more screenshots from this benchmark posted on the web than any other, probably due to its clean and simple. It takes eight measurements: the read and write speeds in megabytes per second for sequential, 512KB, random 4KB and 4KB parallel disk operations.
CRYSTAL DISKMARK BENCHMARKS DRIVER
The Samsung NVMe driver is said to be not needed for this series. CrystalDiskMark is a free disk benchmarking utility that is very simple to use. Simply click on the title for a free copy. Advanced load bench-marking can be configured, as well as full drive information and data erasing via secure erase, enhanced secure erase, TRIM and overwriting. Keep in mind that this is with the Microsoft Windows 10 NVMe driver. TxBench is one of our newly discovered benchmarks that we works much the same as Crystal Diskmark, but with several other features. The 1TB model is rated at 7000 MB/s read and 5100 MB/s write so we were just below the drives rated speeds. CystalDiskMark:īenchmark Results: The Samsung SSD 980 Pro 2TB drive came in with scores of 6754 MB/s read and 5019 MB/s write on CrystalDiskMark 7. 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.
CrystalDiskMark 7.0.0 圆4ĬrystalDiskMark is a small benchmark utility for drives and enables rapid measurement of sequential and random read/write speeds. The two drives with the Phison E18 controller top this chart with ease, but the Samsung 980 PRO series is just behind as is the WD_BLACK SN850. ATTO Disk Benchmark:īenchmark Results: On ATTO Disk Benchmark found that the Samsung SSD 980 Pro 2TB NVMe SSD reached 5.07 GB/s write and and 6.27 GB/s read at the standard queue depth of 4. The test was run with the default runs of 0.5KB through 64MB transfer sizes with the total length being 256MB. It measures raw transfer rates for both reads and writes and places the data into graphs that can be very easily interpreted.
ATTO measures transfers across a specific volume length. I will also do the CrystalDiskMark Test of Adata SU650 along with the Spe. ATTO is one of the oldest drive benchmarks still being used today and is still very relevant in the SSD world. I will tell you the specifications of SU650.
