We will focus here on the Samsung drives as Apple used their ships in MacBooks before. Some popular SSD has been tested in the past. The larger the SSD the bigger TBW it can take. How much the producers declare their SSD can withstand? As I have a 256 GB model I will use value for this model throughout the article. It depends on the size of the SSD, used technology, and quality of chips used for SSD. TLDR: There is nothing to be worried about! In my case, SSD will last from 5 to 50 years! Endurance of the SSDįirst, we have to take a look at how much TBW and SSD can take before they start to fail. In this article, I will show how much data is written to my SSD and if is there anything to be worried about (we will look at the Terabytes written or TBW). I use my Mac for code development, machine learning, and data science for 5 days so my disk is rather used extensively. As I was concerned about my M1 MacBook Air (16GB, 256GB SSD), I decided to actively monitor the use of SDD in my Mac. The worst-case scenario is you’ll need to reinstall macOS in Recovery Mode, which will take some time but will leave all of your files intact.There have been rumors about extensive writes operations to SSD on machines equipped with M1 chip. These instructions were created using macOS Big Sur, but they can also be used in macOS Catalina. If something goes wrong, don’t panic. There are so many times I could’ve saved myself some frustration if I was just more careful with my typing. While the procedure isn’t difficult (if I can do it, you certainly can), since you’re dealing with command line entries, you need to pay a little closer attention to what you’re doing than with apps you usually use on the Mac. In this article, you’ll learn how to set up the Terminal so you can install and run smartmontools. It runs in the Terminal, the command-line interface for the Mac that you’ll find in the Utilities folder inside Applications. It’s not a typical app with an icon that you double-click to launch and menus and windows you navigate. To gain insight into the health of your SSD, you can use a software tool called smartmontools, which taps into the Self-Monitoring, Analysis and Reporting Technology (SMART) system that’s built into SSDs. There is a catch with smartmontools, though. So even if you have a brand new M1 Mac, you might want to check on your drive’s health from time to time. (Earlier this year, there were various reports of Mac SSDs showing advanced wear after just a few months of use, But Apple said this was a data reporting error and fixed the problem in macOS Big Sur 11.4.) While it usually takes a really long time to wear out an SSD-likely far longer than you’ll keep your Mac-problems can arise. Since the SSD is such a vital part of your Mac, it’s a good idea to keeps tabs on its health. But there’s one thing you may not know about SSDs: They wear out over a long period of time. If you have a newer Mac, it likely uses a speedy solid-state drive to store files, apps, music, videos, and a lot of other important stuff.
