Let's retire BlackMagic's Disk Mark and embrance Amorphous Disk. There's plenty of aspects that aren't covered, such as latency, burst performance, power consumed, and mixed random read/writes, but this is a massive step in the right direction for gauging SSD performance on macOS. Also, CrystalDiskMark measures IOPS (Input/Output Operations-per-second), which is similar but also a different measure of disk speed. Usually, an OS wouldn't have that deep of a queue, but the Q1T1 does mimic a singular request. This is a very popular storage benchmarking tool. Download Change List Rebuilt UI (HTML -> GDI) Changed Sequential Benchmark (Block Size 128KiB -> 1MiB) Changed Random Benchmark (Q8T8 -> Q32T16) Added Peak/Real. The default depth is pretty high for the test. All tools were tested on Windows 10 64-bit and are also compatible with Windows 7 and 8. CrystalDiskMark tests random reads and writes both as queued requests and single requests. It takes eight measurements: the read and write speeds in megabytes per second ( MBps) for sequential, 512KB, random 4KB and 4KB parallel disk operations. Random Read and Write tests are as important, if not more so, as many SSDs can deliver fast maximum continuous read and writes but much less so for random small data blocks. CrystalDiskMark is a free disk benchmarking utility that is very simple to use. After multiple runs, CrystalDiskMark will take best reading rather than the average. Let the tests run and watch the various speed fields populate. Chose a drive with the dropdown on the upper right.

This is useful but only measures one aspect of an SSD, and doesn't necessarily mimic accurately how most disk interactions occur. How to use CrystalDiskMark to benchmark your own drive. So why am I always complaining about BlackMagic Disk Speed TestīlackMagic's Disk Speed Test only tests one thing, continuous throughput. While it isn't a direct port, it's heavily inspired by the famed and loved Windows utility, CrystalDiskMark.

The first commenter on FaceBook pointed out that we finally have a good disk benchmark utility AmorphousDiskMark. Awhile back, I made a video about USBc and the classic Mac Pro but lamented yet ago the terrible benchmarking on macOS.
