Your SSD has a hidden write limit, and Windows is counting down to it every single day

Solid-state drives (SSDs) were a premium storage option when I bought my first laptop in 2012. They were fast, and it was one of the reasons for the expensive price tag. Back then, users would prefer to install the OS on a small SSD (128 or 256 GB) while keeping other files on a regular hard drive. As storage became cheaper, SSDs completely phased out HDDs, especially in laptops, which began to include NVMe options. But we rarely think about how the operating system uses it in the background. A casual glance at the Task Manager shows a noticeable spike only when you're installing, copying, or extracting something. It gives a false sense of assurance because the SSD appears idle most of the time. However, your PC keeps hammering zeroes and ones even when you're not using it. Let's explore the reasons behind this approach and the impact on your precious storage. Windows does a lot of stuff in the background Services, telemetry, maintenance, indexing, and more An OS tries to hide its design complexity behind the GUI design. You’re rarely exposed to the actual, continuous resource usage of multiple OS components, such as services, background apps, search indexing, and others. Windows keeps them working silently to offer you the best OS experience possible, and your SSD has to bear some of the brunt due to it. Windows, or rather any OS, tries to keep everything in harmony, be it the services, antivirus scans, event logs, or update installs. While you are busy using apps and your favorite browser, it tries to keep things working on its end by storing event logs, managing paging, and handling temporary files. The OS also rebuilds search indexes for faster search performance, downloads and installs updates, and services system components. Add the incessant file sync from your favorite cloud storage app, the browser trying to update caches and other metadata, applications building thumbnail cache, and it suddenly feels overwhelming for your SSD. Most of these tasks I mentioned above result in tiny but frequent write operations, and you certainly wouldn’t want the SSD to wear out faster than it should. The current memory and storage prices are hard to stomach, and you might have to shell out over $200 to replace a decent NVMe SSD in your laptop or PC. I made the mistake of not buying additional NVMe drives a year ago and waited for a $5-10 drop, which seems insignificant now that prices have quadrupled. But how much can your SSD handle? SSDs can outlast your expectations But endurance ratings matter Credit: Western Digital Not all SSDs are created equal. Just because you have an NVMe Gen-3, 4, or 5 model in your laptop doesn’t make it magically better. One of the key metrics for evaluating your SSD’s lifespan is endurance, measured in Terabytes Written (TBW). It simply tells how much data you can write on the drive before it reaches its rated endurance limit. 600 TBW is a fairly standard number for a typical 1TB TLC SSD, and it means that you can expect to write 600TB of data on it before encountering any failures. It can outlast that number, too, since it's just an estimate, not a definitive measure. On the other hand, SSD models that use QLC NAND flash technology have a lower TBW number. So, an SSD has a limited lifespan, no matter how difficult it seems to achieve that endurance rating. Games and apps have also ballooned in size, and when you deal with an app that writes a huge amount of data in one session, it's not great for your system storage. For example, using video editing software on long footage, using a 3-D modeling tool, running virtual machines in parallel, or frequently installing and removing games can wear out your SSD faster. While these are deliberate actions that you must perform, suppressing the OS-related disk usage can help extend the SSD’s lifespan to some extent. Not all Windows features are helpful Turning off the pesky, unnecessary items Windows has a mix of helpful features and a lot of mildly useful, borderline unnecessary ones. The first course of action should be to disable the ones making a significant dent in the TBW number. I personally disable Fast Startup because it does more harm than good. The feature prevents your PC from completely shutting down and writes to the hiberfil.sys (hibernation file). It can help your PC start a tad faster on the next boot, but the convenience isn't worth it if it writes to the hibernation file every time. On my PC, the hibernation file size is 6.2GB (it varies with RAM size), and I don’t want Fast Startup to perform a write operation every time I do a shutdown. So, you should deactivate Fast Startup, but I wouldn’t suggest disabling hibernation because I use it occasionally, and Windows won’t rewrite the file unless I select the feature in Power settings. You can also turn off any kind of telemetry collection, file indexing (for some volumes), manage startup apps, and disable background services. Apart from the OS side, you can practice preventive measures like using a spare scratch disk for app and game installs and other temporary, large write sessions. I suggest using a free SATA or NVMe slot on your motherboard or a USB connection to the SSD. The same goes for frequent download sessions, rendering huge files in a video editing software, or working with temporary project files. Windows will only focus on managing essential OS features and apps, while most of the heavy lifting will happen on the spare disk. There might be some performance tradeoffs, especially during read-write operations, but it’s worth it. Save your SSD SSDs were cheap for a while, but current market trends have made me realize it's best to avoid excessive wear. I want my main PC to last as long as possible without requiring a hefty component replacement, like a Gen-4 NVMe SSD. You can turn off all the OS-related features that contribute to this problem while also incorporating the habits I discussed above.
