Once you have that information in hand, you can research any anomalies with reported data. Because of this, it's important that you know the make and model of the drive you are testing. First off, it's easy to misinterpret the reported data. There are actually two caveats with smartctl.

Instead, your best bet is to run both the short and long tests and verify the health of your drives via those reports. Why? These are both older drives and do not report ID 177 (Wear_Leveling_Count). However, neither report the Wear_Leveling_Count. Both of these drives report similar (and more comprehensive) data. For example, I have a older Intel and Kingston SSD drives attached to the same machine. One thing to keep in mind is that different manufacturers will report different data with smartclt. As you can see, my Samsung SSD is currently at a 99 for Wear_Leveling_Count, which is a very healthy drive. It is important to look at the value and worst value columns.

Wear_Leveling_Count - Stands for the remaining endurance of the drive in percentage (starting from 100 and decreasing linearly as the drive is written to).

If you're using an older drive, this can be an issue. Most modern SSDs have fairly incredible lifespans, so chances are you're not going to bump into the end of life. Each make/model of drive has a recommended 'shelf life' of hours it can be used.

Power_On_Hours - how many hours the drive has been powered on.

The command will print out the results of the test, as well as all of the information you need to verify the health of your SSD ( Figure C).Ī typical health report on a solid state drive.īeyond the Self-test log, there are two values in the output to be examined: To view the results of the test, issue the command sudo smartctl -a /dev/sdX (Where sdX is the name of the drive tested). The short test takes approximately two minutes to complete, whereas the long test will require between 20-60 minutes (depending upon your hardware).

The entire disk is checked (as opposed to just a section).

No time restriction and in the Read/Verify segment.

The long test runs everything included with the short test, while adding:

Read/Verify: A certain area of the disk will be read to verify certain data (the size and position of the region read is unique to each manufacturer).

Mechanical Properties: Servos and positioning mechanisms are tested (also specific to each manufacturer).

Electrical Properties: The controller tests its own electronics, which is different for each manufacturer.

The short test will examine the following:

This can be installed with a single command: sudo apt install smartmontools The smartctl utility is a part of the smartmontools package. The required package is found on all the standard repositories, so adjust the installation command to fit your particular distribution of choice. I will be demonstrating with the Ubuntu platform (Ubuntu 17.10 to be exact). Even with that in mind, you can get a good estimation as to the wear and tear on your drives.

Because of this, you cannot be certain the number of times your SSD chips have been written to. tools aren't always up to date with every SSD drive. Of course, how much mileage you get from the command will depend upon what make/model of SSD you employ. With this command, you can get a quick glimpse of your SSD health. Why? Most of the time, your Linux servers won't include a GUI with the command line, you can easily make use it by secure shelling into your remote Linux server and run your tests from the terminal. Although a GUI solution exists (GNOME Disks), I highly recommend going with a command line tool for this task. How do you check the health of those drives? As with everything in Linux, there are options. The last thing you want to do is fall victim to that particular end of days. Why? Because, even though solid state drives will dramatically outlast rotating platter drives, they do have a finite lifespan. If your data center makes use of Linux machines, one of the administrative tasks you'll want to undertake is regularly checking the health of the SSD drives used on those machines.
