It has a set of command line tools that your Mac needs before you can install and run Homebrew, which is a prerequisite for running smartmontools. The first thing you need to do is install Xcode, an Apple app for developers. 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. 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. 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. To gain insight into the health of your SSD, you can use a software tool called But if your drives get a couple hours of idle time daily, it's probably fine.So even if you have a brand new M1 Mac, you might want to check on your drive’s health from time to time. But the drive needs to be powered and idling. So if it's being hammered all the time, it might not be a bad idea to have two drives where it swaps between them on a daily or weekly basis, giving the other one time for garbage collection and wear leveling. One thing with SSD's is they do need some downtime, however, to properly wear level and for garbage collection. I know it sacrifices some file space, but it's better in the long run, especially for lots of writes. This will help with wear leveling as well as maintain speed. If your drive doesn't come with over-provision software, just repartition the drive so there's at least 20% of empty space at the end. It'd be much more cost effective to replace the drive every couple of years with a consumer level drive.Īlso, buy a larger capacity drive, the write endurance is greater, mainly because there's more cells overall, so 2TB of data on a 2TB drive is just one Write cycle, where 2TB on a 512GB drive is four.Īdditionally, be sure to over-provision (OP) your drive if you're using it a lot. But those drives are expensive, and geared more towards enterprise server operations. If you can find an SLC or MLC drive, those have much larger write endurance because it's only one or two bits per cell instead of multiple bits. Yes, best you can do is monitor it on a regular basis. Just make sure to tag the post with the flair and give a little background info/context. On Fridays we'll allow posts that don't normally fit in the usual data-hoarding theme, including posts that would usually be removed by rule 4: “No memes or 'look at this '”
