That is something that we are not doing in this review and it takes more time and effort to do it like we are. Many sites test storage drives as an empty secondary drive and disable drive indexing on that drive to improve their benchmark numbers. Please keep in mind that these scores are on the SN850 running as the primary OS drive and it is filled to 55% capacity. It’ll look like this: Across the top, set the first three dropdowns to: 1 the number of test passes you want to run. In this tutorial it is explained how to use Crystal Disk Info, how to get detailed information about your hard drive HDD & solid-state drive SSD and other fl. Very solid scores for an AMD Ryzen 5 3600X system with no optimizations and a standard install of Windows 10. 4KiB Q32T1: Random read and write data on data areas Q is 32, T is 1. 4KiB Q8T8: The data is read randomly on the data areas, with Q being 8 and T being 8. Usually this test mode will give the fastest speed. The Random 4K performance at QD1 was 74 MB/s read and 229 MB/s write. CrystalDiskMark is a tool to check the read and write capabilities of drives such as HDD. CystalDiskMark:īenchmark Results: CrystalDiskMark 7 is pretty much the industry standard to get peak performance numbers and here the WD_Black SN850 2TB PCIe Gen4 x4 SSD topped out at 7,034 MB/s read and 5131 MB/s write at QD8. 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. The Emulation tab shows two pieces of information to focus on: the Document mode (1), and the text below the dropdown list (2). To open the Developer toolbar, press the F12 key and then select Open DevTools. We charted the results of the drive at the 128KB I/O size and found that it had the second highest read speed of any that we have ever tested and the third highest write speed.ĬrystalDiskMark is a small benchmark utility for drives and enables rapid measurement of sequential and random read/write speeds. Use the F12 Developer Toolbar's 'Emulation' tab in IE 11, shown in the next screenshot to investigate the scenario you want to fix. ATTO Disk Benchmark:īenchmark Results: On ATTO Disk Benchmark found that the WD_Black SN850 2TB PCIe Gen4 SSD topped out at 4.79 GB/s write and 6.56 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. ATTO is one of the oldest drive benchmarks still being used today and is still very relevant in the SSD world.
