Read performance remains strong, and performance is very consistent throughout the test. WD Black SN750 500GB ATTO 256MB WD Black SN750 500GB ATTO 256MB ChartĪTTO is always slightly harder on drives than CrystalDiskMark, and that is the case here. ATTO was tested at both 256MB and 8GB file sizes. The ATTO Disk Benchmark has been a staple of drive sequential performance testing for years.
Moving to the larger 8GB test set, reads hold steady but write speeds drop quite a bit. WD Black SN750 500GB CrystalDiskMark 8GB WD Black SN750 500GB CrystalDiskMark 8GB Chart This performance is near the top end of what you can expect from a PCIe 3.0 NVMe SSD for reads, and just slightly behind the top-performing drives in writes. The WD Black SN750 500GB hits the rated 3430 MB/s read and 2600 MB/s write sequential transfer numbers here almost exactly. WD Black SN750 500GB CrystalDiskMark 1GB WD Black SN750 500GB CrystalDiskMark 1GB Chart CrystalDiskMark 7.0.0 圆4ĬrystalDiskMark is used as a basic starting point for benchmarks as it is something commonly run by end-users as a sanity check. Some previously tested QLC-based PCIe 3.0 SSDs do not pass all these tests, and no SATA based drive can do so. WD Black SN750 500GB BlackmagicĪs a PCIe 3.0 NVMe SSD, the WD Black SN750 500GB has a good showing here and handles every format this benchmark can test for. It shows whether a storage device is suitable for throughput required at a given video format. This is a popular speed test in the video community. This allows us to see the difference between lighter and heavier workloads.
We are moving towards using larger test sizes on our benchmarks, but on several tests, we also used the smaller default test sizes.
