GoKawiilWhen you build a new PC, there are many things to factor in. I personally like to build rigs that, first, are capable of the tasks that I want them to perform, and secondly, are equipped with components and specs that can afford me some amount of future-proofing. In my household, we operate a trickle-down system, where my son inherits my PC bits and pieces when I upgrade parts, so they can’t be too out of date, or I get complaints.
I use my PCs for video editing, streaming, and various other content creation and productivity tasks, but I also use them for some PC gaming fun. There’s always a pull towards going for the biggest and the best when building a gaming PC, so you can have settings dialed up to the max, with incredibly smooth frame rates on a ridiculously expensive monitor with an insane refresh rate. But unfortunately, I don’t have unlimited funds.
Everyone knows that having a higher-end graphics card, with bigger processors and more VRAM, has a direct impact on how your game runs, but what’s not so clear is how much effect your SSD storage pick has on your game's performance metrics. The short answer is that it’s not as important as your CPU or GPU, but it typically only has a slight effect on your game performance, depending on the game you're playing and whether it’s streaming levels or pre-loading them.

The most important thing to first factor in with an SSD is the capacity. Games have grown in size exponentially over the last decade, with some of the latest titles demanding up to 150GB and more just for the one game. My son's Ark: Survival Evolved game with all the added DLC content fills up a 512GB SSD on its own, so if you have a lot of games that you want ready to play at a moment's notice, then you need a larger capacity SSD to have them all installed. In my gaming PC, I have 6TB of storage, which is ample for me, and because I don’t have the fastest internet connection, I prefer to keep my games installed.
If you have an amazingly fast internet connection with high download speed capabilities and don’t need to worry about any kind of metered connection rates, then this will also affect how much storage you need. If you can download any game you want in 5-10 minutes or less, then capacity isn’t as big a concern. You can just uninstall and reinstall a game whenever you want, provided you aren’t in the danger zone with your SSD endurance metrics. The minimum-sized SSD I’d recommend, though, is a 1 TB drive.
If you’re running a traditional hard disk drive for gaming, you should definitely upgrade. An HDD has an average read speed of 100-150 MB/s, compared to the latest PCIe 5.0 SSDs that have peak read speeds of around 14,500 MB/s. Now, although you don’t need read speeds that fast for gaming, the difference is humongous. A game running on an HDD may take 45 seconds to load a level, compared to just a few seconds for the SSD. Even the oldest SSD technology would be an improvement over your optical disk.
When building or upgrading a gaming PC, SSD manufacturer marketing often pushes massive sequential speeds (like 7,000 MB/s or 14,000 MB/s). However, the real-world impact of read and write speeds on actual gameplay is much more nuanced. The effect that a superfast PCIe 5.0 SSD has on frame rates compared to a PCIe 3.0 SSD is virtually imperceptible, as the frame rate rendering is predominantly handled by your GPU, VRAM, CPU, and system RAM. Your PC will use your SSD to load game assets from storage into the VRAM/RAM, and then mostly sit idle during the rendering of the game while you’re playing it.

If you’re playing a game with a massive open world or large levels, there may be the occasional request for assets (textures, models, shaders, etc.), but the most important spec of your SSD in that scenario will be its IOPS speed, or random read speed. Write speeds typically do not affect active gameplay performance, as playing a game predominantly consists of read operations.
