Welcome to this User Tip on how to use DriveDx. DriveDx is a great App for checking the health of storage devices on your Mac.
Getting the DriveDx App
You can get DriveDx here (https://binaryfruit.com/drivedx). For a simple check of your drives, the free trial is fine. No need to pay. However, the premium version does include more features and you can use it indefinitely. You can read more here: DriveDx & DriveDx Store.
Using DriveDx and Uploading the Report
Once you have downloaded DriveDx, open the downloaded App.
In the App, select "Try Now" to start your trial and get the drive information you need.
You will then see a list of devices in the left sidebar. Select the device that you want to get a report for, and click "Save Report". If you have a Fusion Drive, there will be two entries of your internal drive listed, since one is the SSD and the other is the HDD. Click "Save Report" for both in this case.
The report(s) will be saved in a text format.
From here, copy the saved report. You can then use the Additional Text function on Apple Support Communities to paste the DriveDx report. If you have multiple reports, use the Additional Text function multiple times to upload both reports separately.
This should appear:
Give your DriveDx report a Title in the "Title" field, and paste the report in the "Add a note, error log, etc..." area.
This is what the final product of a DriveDx report should look like:

If DriveDx reports your Drive is failing
Should DriveDx report your drive is failing, back up all data immediately. Even if your drive isn't failing, it is still a good idea to have a backup. The best way to create a backup is using Time Machine: Back up your Mac with Time Machine - Apple Support. For Time Machine, you need an external hard drive. Apple sells external hard drives. Here are some options:
Mac computers with USB-A and/or USB-C Connectivity (these drives ship with USB-A and USB-C Cables):
I hope you found this User Tip helpful. If you have any questions, you can ask below, or start a new question thread here on Apple Support Communities.
Great start. One thing to mention, backup your data more frequently if you believe your drive is closer to failure.
Furthermore, considering a drive closer to failure is likely to result in corrupted backup files, make those last backups to a separate medium than the last known good backup.
