Some models of SSD cannot save video data at the speed indicated by the manufacturer because the disk uses hidden data compression to reach these higher write speeds. Important note about Solid State Disk (SSD) speeds

1 stream of 1080p59.94 video at 59.94 fps per stream.

1 stream of 1080p50 video at 50 fps per stream.

2 simultaneous streams of 1080i50 video at 25 fps per stream.

This storage speed is capable of supporting the following video formats: If the result for “HD 1080” is 70, you can run up to 70 frames of HD 1080 video per second. The “How Fast” results panel also enables you to see how many streams of video can be supported by your disk storage. In this example, it would be best if a conventional disk array of hard drives showed performance of at least 30fps to be safe. However conventional hard disks slow down significantly as they fill up and a larger safety margin is required for reliability. SSD storage does not fluctuate much in speed and so an SSD disk array would not need to perform much faster than the video format. A faster disk array or a less demanding video format should be used for reliability. If the “Will it Work?” panel shows a green checkmark for 2K in 10 Bit YUV 4:2:2, but the “How Fast?” panel shows that a maximum of 25fps will be supported, the disk storage performance is too marginal to be reliable. The “How Fast?” results panel shows the frame rates your drive can achieve in frames per second and should be read in conjunction with the “Will it Work?” panel. To stop the test, click the Start button. Notes: The entire test takes about 16 seconds, but it repeats over and over again.

Click the Speed Test Start button and watch as the information loads on the screen.

But you can use third-party software to perform the same task. MacOS doesn’t have any native method to measure the speed of an external hard drive. If required, back up the drive or replace it with a new one. And, if the speed turns out to be slow or abysmal, act appropriately to fix the issue. In this blog, we’ll share a free software method that can help you perform the task efficiently on an external hard drive. Summary: Yes, you can check the read and write speed of your external hard drive on Mac.
