UPDATE NOTE: However, given the seeming inaccuracy of all speed measurement tools, and the fact that AmorphousDiskMark uses MiB and GiB to define test file size, it is impossible to say whether this software is accurate. Media creators should just use the top line test in most instances. It provides more details that are meaningful to a wider range of users. Once you find a tool you are comfortable using, use it consistently.ĪmorphousDiskMark is another tool we can use to measure storage speeds. I wouldn’t obsess too much over test result variability, provided that tool is essentially accurate. However, consistency does not necessarily mean accuracy. BMD delivers extremely consistent results, while AmorphousDiskMark varies a bit more. The closer standard deviation gets to zero, the less the variation. The Standard Deviation shows the variations between these tests. We are currently unable to tell which software is more accurate.

UPDATE NOTE: However, there is debate currently on the accuracy of Blackmagic Disk Speed Test. As you can see looking at the green fields in this table, write speeds were reported about 8% slower, on average, and read speeds were reported about 2% slower. This table compares the speed of AmorphousDiskMark 4.0 to Blackmagic Disk Speed Test by running three tests each, then averaging the results. Again, I would compare the top line numbers. Make sure you are looking in the correct column before comparing numbers. NOTE: Read and write results are reversed between these two tests. Most of the time, I pay attention to the top line.Ĭomparing AmorphousDiskMark with Blackmagic Disk Speed Test shows variations in speed, so let’s look a bit deeper into those variations. Just click the buttons indicated by the red arrows. However, the last two tests are not generally needed for media creators, so, to save wear and tear on your storage, you don’t need to run these. To run all four tests, click the All button at the top. You can also set the number of tests, but the default setting of 5 is fine. MB will affect reported speeds with MiB up to 8% faster. Computers actually format data as powers of 2, so an MB is 1,024 KB while a GB is 1,024 MB. NOTE: MiB and GiB are marketing labels that define a megabyte as 1,000 KB and a gigabyte as 1,000 MB. Media creators should pick a larger file, around 4 GiB. Testing for databases or office files should pick a small file size, around 64 MiB.

Next, determine the size of the test file. NOTE: Unlike hard drives, SSDs don’t change speed as they fill up. Installation is trivial and works just as you would expect.Īfter starting the application, select the storage you want to test from the popup menu at the top.

If you want a detailed look as how fast your storage is, AmorphousDiskMark 4.0 provides a fast – and free – way to analyze your storage in depth.ĪmorphousDiskMark is available from the Mac App Store. The only downside is that you need to know which results apply to you and ignore those that don’t. What I like about this test is that it provides more detailed results that are applicable to a larger range of users (media creators, database administrators and IT specialists). Running a complete test takes about five minutes and yields results similar to, but slightly lower than, Blackmagic Disk Speed Test. Media creators should pay attention to the top two lines in the on-screen report and ignore the bottom two.

This simple-to-use utility analyzes storage performance two ways: sequential read/write (typical for media creators) and random access (typical for database and small file operations).

I’m running these tests on an M1 MacBook Pro and testing a Samsung T5 PCIe SSD. Katsura Shareware was founded in 2004 to “create shareware that makes your Mac more useful and fun to use.” So far, they’ve published 16 different utilities.ĪmorphousDiskMark was released in January, 2022, and requires macOS 10.9.5 or later. IOPs (input/output operations per second) are more relevant for database or office operations which write or read smaller chunks of data. NOTE: MB/second is more appropriate for media creators because it measures how quickly files will transfer between storage and the computer. It joins Blackmagic Design Disk Speed test, AJA System Test Lite, and Activity Monitor in helping us determine if our storage is fast enough to handle the media we need to process. This free utility measures the speed of Mac-connected storage in both MB/second and IOPs.

This can be compensated for in how the code is written, but there’s no way – from the outside – to tell if this correction is being made.Īfter reading my recent commentary about at the speed differences between Blackmagic Disk Speed Test and AJA System Test Lite, Lee suggested I look into AmorphousDiskMark, a Mac utility from Katsura Software. 15, 2022,): Measuring storage speeds using MiB and GiB, instead of MB and GB, can result in over-stating storage speed by up to 8%.
