SSDs and HDDs, both have an expiration date. Once the time comes, your SSD and HDD will fail to work and all saved data will likely be lost.
That’s why it is important to check the health of your SSD and HDD once in a while, so you don’t lose your data all of a sudden.
There are plenty of applications to check it on a PC but how can you do it on your Mac?
In this article, I have discussed how to perform an SSD health check on Mac.
Why Disk Health Check Is Important
SSDs have rights of early failure and once the early period is over for an SSD, it can survive for a certain number of write cycles only.
Once the number exceeds the limit, the SSDs will have a total failure and no data recovery is possible from it.
For HDDs, it’s a bit different. HDDs also have a high chance of failure at the start, but if the HDD drive spins up properly at the start, it will last for years until its end of life is reached due to wear-based failure.
This is why it’s important to know how long your SSD or HDD will last, or you risk having complete data lost.
3 Ways Check SSD Health On Mac
There are several ways to track the SSD health on Mac and one of those ways is provided by Apple on your Mac.
I have mentioned all the ways you can do it here so use the method you find best.
1) How To Check SSD Health Using SMART Status System Reports
SMART or Self-Monitoring Analysis and Reporting Technology is a system on your Mac that can automatically check your SSDs and HDDs.
macOS uses SMART to track the status of all drives. You can use this report to check the SSD health on Mac.
So, on Mac check SSD health using the following steps:
- Select the Apple icon located in the upper left corner of the screen. A menu will appear.
- Press the Option key. You will notice that the About this Mac option changed to System Information. Click on it.
- Expand the Hardware section from the left side and click on the Storage option.
- Click on the Drive you want to check and the Smart status will be present on the bottom of the right panel.
You will either see Verified, Failing or Fatal in the SMART status.
Verified means the drive is not reporting any problems, failing means the drive has reported an error and may soon become Fatal, which means near it to back up your data before it completely fails.
2) How To Check SSD Health Using Smartmontools
For those that have Homebrew installed on their Macs, they can install Smartmontools and use it to check the Mac SSD health.
By doing this, they will basically have the SMART status show up on the Terminal.
This will provide a more detailed understanding of the health of your SSD than the three categories your macOS gives on the above method.
Here is how you can do it:
- Open Terminal and write the following command and run it for installing Smartmontools with Homebrew on your Mac:
brew install smartmontools
- Once you have done that, run the command given below to get the drive identifier for the volume that you want to test:
- Or you can look up the drive identifier from System Information in the Storage section next to BSD Name.
- Now write the following command and press Enter to initiate it to learn the SMART status for the drive you want. Remember to enter the actual BSD name of the drive instead of “BSD Name in the command”.
smartctl -a BSD Name
3) How To Check SSD Health Using 3rd Party Tools
The 3rd way you can check the health of your Mac’s SSD is using 3rd party tools.
If you are not satisfied with the information provided by SMART or find it too much work, then you can try their 3rd party applications.
There are plenty of apps out there like DriveDX, Stellar Drive Toolbox, CleanMyMac, etc. See which one you like and use them.
So, there you have it. Now you know how to perform an SSD health check on Mac. If you have any queries regarding this topic, ask them in the comment section below.
