How to Check SSD Health on Mac

The solid-state drive (SSD) on your Mac is the central storage of all your digital files and plays an important role in maintaining the smooth functioning of your system. It is of utmost importance to regularly monitor the health of your SSD to prevent any data loss, ensure system stability, and extend the drive’s lifespan on your Mac device.

This guide provides valuable information on how to use macOS to check drive health to understand SMART attributes, locate drives, and adopt best practices to optimize the performance of your SSD.

S.M.A.R.T Technology and SSD Health on Mac

S.M.A.R.T is an incorporated system in SSDs that monitors different aspects concerning the health and performance of the drive. It consistently tracks the drive’s functionality, identifies possible problems, and supplies data that can signify the overall condition of the drive. Mac OS uses this technology to offer information about the state of the SSD.

S.M.A.R.T attributes are metrics or indicators that the drive continuously monitors and provides reports on. These attributes provide valuable data about the health, potential risks, and overall performance of the drive. By analyzing these attributes, users can predict drive failure, recognize warning signs, and proactively preserve the health and functionality of the SSD on their Mac.

Check SSD Health Mac with Tools

If you want to check the disk of your Macbook, it is a good idea to use the smartctl tool. It is a command-line tool used to query and monitor the SMART attributes of storage drives, including SSDs, on Mac systems. The smartctl allows users to access detailed information about the drive’s health, performance, and potential issues by retrieving and interpreting the SMART data stored within the drive.

Using smartctl for ou to Check Disk Health on Mac

  • 1. Access Terminal

    Open Terminal on your Mac. You can do it by going to Applications > Utilities > Terminal or by using Spotlight Search (Command + Space, then typing "Terminal").

  • 2. Install smartctl on Mac

    If your system doesn't already have smartctl installed, you can obtain it through package managers like Homebrew. You can install Homebrew by following the instructions on their website and then install smartctl by running the command: " brew install smartmontools " .

  • 3. Execute smartctl Command

    To check the SSD health, use the following command in Terminal:

    1. smartctl -a /dev/your_ssd_name
    2. Replace /dev/your_ssd_name with the appropriate identifier for your SSD. It could be something like /dev/disk0.

  • 4. Interpret Results

    Once you execute the command, smartctl will generate a detailed report that shows various attributes of the SSD, including its health, temperature, error rates, and more. Interpret the data to understand the SSD's condition.

Check Drive Health on Mac Using Disk Utility Tool

  • 1. Accessing Disk Utility

    • Using Finder: Go to Finder > Applications > Utilities and then open Disk Utility.
    • Using Spotlight: Use Spotlight Search (Command + Space) and type "Disk Utility," then press Enter to launch the application.

  • 2. Select Drive

    In Disk Utility, a lineup of drives will be visible on the left-hand side. Select the SSD from the list of drives that are currently accessible.

  • 3. Check SMART Status

    Click on the "First Aid" tab within Disk Utility. Here, you can find the SMART status of your drive. If it indicates "Verified," your SSD functions within normal parameters. If it shows any other status, it might indicate a potential issue.

Using Disk Utility provides a user-friendly graphical interface to check Mac disk health, SMART status, and basic health information of your SSD, allowing for quick checks without the need for command-line expertise.

Interpreting Results and Understanding SSD Health Metrics on macOS

When using tools to check SSD health on macOS, interpreting SMART attributes provides crucial insights into the drive’s condition:

Power-On Hours (POH): Tracks the cumulative operational hours of the drive. High values may indicate aging but not necessarily imminent failure.

Reallocated Sectors Count: This represents the number of sectors relocated due to errors. A consistent rise might indicate potential problems with the drive’s health.

SSD Wear Leveling Count: Indicates how evenly data is written to the drive, affecting its longevity.

Temperature: Monitors the drive’s operating temperature. Elevated temperatures can lead to reduced drive lifespan.

Uncorrectable Errors: Reflects errors the drive cannot rectify, signifying potential issues.

Regular monitoring and understanding of these attributes gives a comprehensive overview of the SSD’s health, enabling proactive measures to be taken before significant issues arise.

Identifying Warning Signs and Potential Issues

Recognizing warning signs in the SMART attributes helps in identifying potential issues:

  • Sharp Increase in Reallocated Sectors: A sudden rise might indicate a failing drive.
  • Consistent Write Amplification: High write amplification could accelerate wear on the drive.
  • Persistent High-Temperature Readings: Continuous high temperatures can significantly impact the drive’s lifespan and performance.

Attention to these warning signs assists users in taking necessary steps to prevent data loss or system instability by addressing potential problems early on.

Knowing When to Replace or Upgrade the SSD on Mac

Deciding when to replace or upgrade the SSD is crucial for maintaining system reliability:
Failed MacBook Data Recovery

Suppose S.M.A.R.T attributes consistently indicate deteriorating health, frequent errors, or persisting warning signs despite attempts to resolve them. In that case, it might be time to consider replacement or upgrading to a new SSD.

As SSDs age, their reliability decreases, making proactive replacement or upgrade a smart preventive measure against potential drive failures.

Regularly monitoring and understanding the SMART attributes allows users to make informed decisions regarding the maintenance or replacement of their SSDs, ensuring data safety and system stability on macOS.

Best Practices for Maintaining SSD Health on Mac

Safeguarding your data is paramount. By implementing regular backups and efficient data management practices, you ensure the safety of your crucial information and alleviate unnecessary strain on your SSD.

Regular Backups: Creating frequent backups of your important data is essential. Use macOS’s Time Machine or third-party backup solutions to ensure that if an unexpected SSD failure occurs, your data remains safe and easily recoverable.

Data Management: Practice efficient data management to reduce unnecessary write cycles on the SSD. Deleting unwanted files, utilizing cloud storage, and employing external drives for large files can help minimize the strain on the SSD.

Firmware Updates and Maintenance Tips

To maintain the optimal health of your SSD, keeping the firmware updated is crucial. Additionally, performing routine maintenance tasks and ensuring TRIM support can significantly contribute to your drive’s longevity and performance.

Firmware Updates: Ensure that your SSD firmware is always kept up-to-date. Frequently, manufacturers provide firmware updates to enhance performance, resolve bugs, and tackle any potential issues.

TRIM Support: Ensure TRIM support is active on your Mac. TRIM helps optimize SSD performance by proactively clearing old data, which can enhance the drive’s lifespan and maintain performance over time.

Periodic Maintenance: Regularly perform macOS system maintenance tasks, such as clearing caches, managing startup items, and verifying disk permissions. This assists in optimizing overall system health and indirectly benefits the SSD.
