![]() ![]() What’s more, modern SSDs use wear-leveling technology to distribute data evenly across all physical sectors, prolonging the total lifespan.īecause of all these factors, most estimates put the age limit for SSDs around 10 years. While that may not sound like much, it’s important to realize that SSDs don’t degrade when reading data-only when writing new data. We know that Apple uses Toshiba TLC NAND flash chips for its SSD drives, which should endure up to 3,000 write cycles per physical sector based on the current lithography process. That doesn’t mean that they would instantly become unusable, but their users could experience major stability issues and, in extreme cases, data loss. Recently, several M1 Mac power users have shared alarming usage reports indicating extremely high drive writes over a relatively short time.īased on the wear of the SSD inside his 2 TB M1 Mac, developer Hector Martin calculated that 256 GB models could exceed their TBW in less than half a year. Method 3: Download a Free SSD Health Utility (Disk Drill).Method 2: Use a Paid SSD Drive Checker (DriveDx).Method 1: Check SMART Status on macOS with Disk Utility.All relevant information will be displayed in an extremely intuitive and easy-to-understand manner. While the DriveDx application is open, the application continuously monitors the SMART status to identify any abnormalities or problems that appear on the hard drive in real time. This application can scan all connected drives on the system and provide a complete picture of the health of your storage system.ĭownload DriveDx and install it on your Mac like any other regular application. This is a hard drive health diagnostic tool that can give you the most detailed view of your SSD's health. If you feel that the built-in hard drive testing tool gives a bit of sketchy information, use specialized third-party hard drive monitoring applications, such as DriveDx. In addition, SMART's numerical error code system will also provide you with more information about the specific problem that the hard drive is experiencing. Conversely, a status showing 'Failing' indicates that the hard drive is showing signs of abnormal activity, and may soon enter the 'Fatal' state, which means that the hard drive has failed. The 'Verified' status you see in this example indicates that the device's hard drive is currently in a working state, with no reported problems. You will find the SMART status at the bottom of the list on the right (usually the last item in the list). Next, select the drive that you want to check from the list on the right side. When the 'System Information' screen opens, look for the Storage section in the Hardware section on the left side of the screen. You should see the 'About this Mac' section change to 'System Information'. Click the Apple icon in the top left corner of the screen (in the toolbar), then hold down the Option key. The process of checking SSD health on macOS is generally very simple and fast. In addition, there will also be a number of tools to help you analyze this state with different levels of detail. macOS has a built-in tool that monitors the SMART status of all hard drives on the system by default. By checking the SMART index, you can get an overview of the current status of the hard drive, thereby making the appropriate treatment plan. Self-Monitoring, Analysis and Reporting Technology (SMART) is an automated testing system for SSDs and other traditional hard drives. Check SSD status with SMART Status System Reports This article will show you some effective methods to check the health of SSD drives on your Mac. Therefore, it is extremely necessary to regularly check and monitor the 'health' of the hard drive. Any problems or failures related to the hard drive will cause your computer to stop working completely. The hard drive is one of the extremely important components on any PC system, and the Mac is no exception.
