The Ultimate 2024 Guide: How to Add More Storage to Your Gaming PC (The Easy Way)

Leave a Comment / Business software, technology

Ever felt that digital heart-sink? You just bought the latest AAA title, you click “Install,” and Steam hits you with the dreaded “Not Enough Disk Space” error. Your 1TB drive, which felt impossibly huge five years ago, is now a digital closet overflowing with giant games. Modern games like Cyberpunk 2077 or Call of Duty can eat up over 150GB each. Your gaming PC running out of space isn’t just an annoyance; it’s a barrier.

But what if you could fix this, easily, and for less money than you think? This guide is your ultimate resource. We’re not just talking about deleting files. We’re diving deep into the easy, affordable, and performance-boosting ways to add more storage to your gaming PC. We’ll cover everything from simple software tricks to the step-by-step process of installing a new, blazing-fast SSD. No advanced technical degree required.

Why Your Gaming PC Storage is Suddenly Full

It’s not your imagination; games are getting massive. This explosive growth is due to several factors:

  • 4K Textures: High-resolution graphics require incredibly detailed image files (textures). To make that beautiful, photorealistic world, developers pack in gigabytes of texture data.
  • Uncompressed Audio: To deliver immersive, high-fidelity sound, many games now use uncompressed or minimally compressed audio files, which are significantly larger.
  • Live Service & DLC: Games like Destiny 2 or Apex Legends are constantly adding new content, seasons, and updates, all of which permanently increase the game’s file size on your drive.

A full hard drive doesn’t just mean you can’t install new games. It can also slow down your entire system. Your operating system (Windows) needs free space to work (as ‘virtual memory’ or for swap files). When your main drive is full, you can experience system-wide slowdown, longer boot times, and even crashes.

Part 1: The First Step – Digital Cleaning Before You Buy

Before you spend a dime, let’s perform a “digital deep clean.” Sometimes, you can reclaim a significant amount of space in just 10 minutes.

Use Windows Storage Settings

Windows has a great built-in tool.

  1. Go to Settings > System > Storage.
  2. You’ll see a breakdown of what’s using your space.
  3. Look for “Temporary files”. This is a goldmine. Windows often keeps old update files, error logs, and other junk. Check the boxes (especially “Downloads” if you’re brave, and “Recycle Bin”) and click “Remove files”. You could instantly free up 20-50GB.

The Great Game Uninstall

Be honest. Are you really going to play that a-bit-disappointing 2019 shooter again? Go through your Steam, Epic Games, and GOG libraries.

  • Steam: Right-click a game > Manage > Uninstall.
  • Epic/GOG/EA App: Find the “Uninstall” option in the game’s settings.

You can always reinstall them later! The goal here is to make space for the games you play right now.

Use a Tool Like TreeSize Free

Want to know exactly where your space has gone? Download a free tool like TreeSize Free. It scans your drive and shows you a visual map of the biggest folders. You’ll often find an old 40GB video render you forgot about or a game you thought you uninstalled. This is one of the best ways to find large hidden files on your PC.

Part 2: Understanding Your Upgrade Options: HDD vs. SATA SSD vs. NVMe SSD

Okay, you’ve cleaned, and you still need more room. It’s time to buy new hardware. This is the single biggest performance-per-dollar upgrade you can make, besides RAM. Your choice comes down to three main types of internal storage (and one external option).

1. HDD (Hard Disk Drive): The Bulk Storage King

  • What it is: The “classic” hard drive. It uses spinning magnetic platters and a physical arm to read/write data.
  • Pros: It’s incredibly cheap. You can get a massive 4TB or 8TB drive for a very low price.
  • Cons: It’s slow. Games will load slowly, Windows will boot slowly, and you’ll feel the lag.
  • Best for: A secondary “archive” drive. This is the perfect place to store your “cold” game library (games you’re not actively playing), movie files, photos, or project backups. It’s the best bulk storage solution for gamers on a budget.

2. SATA SSD (Solid-State Drive): The Gold Standard

  • What it is: This is the most common type of SSD. It’s a “block” of flash memory (no moving parts) and connects to your motherboard using a SATA cable. It’s usually a 2.5-inch drive, the size of a laptop hard drive.
  • Pros: A massive leap in speed from an HDD. Games load 5-10x faster. Windows boots in seconds. They are affordable and easy to install.
  • Cons: Slower than the newest standard (NVMe), but frankly, you won’t notice for most gaming.
  • Best for: Almost everyone. This is the best all-around storage for gaming PCs. It’s the perfect balance of price, performance, and ease of installation. A 1TB or 2TB SATA SSD is the “sweet spot” for a primary game drive.

3. NVMe M.2 SSD: The Blazing-Fast Specialist

  • What it is: This is the new-generation champion. It’s a tiny “stick” of memory that plugs directly into a special M.2 slot on your motherboard, bypassing cables entirely. It uses the much-faster PCIe bus (like your graphics card).
  • Pros: The fastest storage for game loading times available, period. It’s 5-7x faster than a SATA SSD (and 50x faster than an HDD). The small form factor also means less cable clutter.
  • Cons: More expensive (though prices are dropping fast). Your motherboard must have a dedicated M.2 slot to use one. For just gaming, the real-world difference in load times between a SATA SSD and an NVMe SSD can be small (maybe 2-3 seconds).
  • Best for: New builds and performance enthusiasts. If you’re building a new PC or have a modern motherboard, this is the way to go. It’s the best SSD for your operating system and main games.

4. External SSD/HDD: The Easiest Way

  • What it is: A hard drive or SSD in its own case that plugs into your PC via a USB port.
  • Pros: Incredibly easy. You just plug it in. No opening your PC case, no screwdrivers.
  • Cons: Slower than internal options (even an external SSD is limited by the USB port speed). You have a cable and a box sitting on your desk.
  • Best for: Laptop gamers or the truly tech-phobic. An external SSD for a Steam library is a perfectly valid and simple solution if you just want more space right now.

Part 3: How to Install a SATA SSD in Your Gaming PC (Step-by-Step)

This is the most common upgrade. Let’s walk through the easy way to install a 2.5-inch SATA SSD.

Tools Needed:

  • Your new 2.5-inch SATA SSD.
  • A Phillips-head screwdriver.
  • A SATA data cable (your motherboard might have come with a spare; if not, buy one, they’re cheap).

Step 1: Safety First!

  • Shut down your PC completely. Not sleep, a full shutdown.
  • Unplug the main power cable from the back of your PC.
  • Move your PC to a well-lit area with room to work (like a table).
  • Touch a large metal part of your PC case before you touch any components. This grounds you and prevents static electricity from damaging your new drive.

Step 2: Open Your PC Case

Most modern cases have a tempered glass or metal side panel held on by a few thumbscrews at the back. Remove them, and gently slide or swing the panel off.

Step 3: Find a Spot to Mount Your SSD

Look for a drive bay.

  • Modern Cases: Many cases have dedicated 2.5-inch SSD mounting spots, often on the back of the motherboard tray or in small, removable “caddies.”
  • Older Cases: You might have a larger 3.5-inch drive cage. If so, you may need a simple “2.5-inch to 3.5-inch adapter bracket” to make your small SSD fit.

Secure the SSD to the caddy or bracket using the small screws that (usually) come with your SSD or case.

Step 4: Connect the Cables (It’s Just Two!)

There are only two cables to plug into your new SATA SSD.

  1. The SATA Data Cable: This is a small, thin cable (usually red or black) with an “L” shaped connector.
    • Plug one end into the back of your new SSD.
    • Plug the other end into a free SATA port on your motherboard. These are usually in a group on the bottom-right of your motherboard.
  2. The SATA Power Cable: This is a wider, flat cable coming from your Power Supply (PSU).
    • Find a spare SATA power connector (they often have multiple connectors on one cable) and plug it firmly into the larger “L” shaped port on your SSD.

That’s it. The physical installation is done.

Part 4: How to Install an NVMe M.2 SSD (The “Stick”)

This is even easier in some ways, as there are no cables.

Tools Needed:

  • Your new NVMe M.2 SSD.
  • A small Phillips-head screwdriver (like one for glasses).

Step 1: Safety First!

Same as before: Shut down, unplug, and ground yourself by touching the case.

Step 2: Locate Your Motherboard’s M.2 Slot

  • Consult your motherboard’s manual. This is the most important step.
  • M.2 slots are small, horizontal slots on the motherboard itself. They are often located:
    • Between the CPU and the graphics card.
    • Below the graphics card.
    • Near the bottom edge of the motherboard.
  • Many motherboards have a “heat spreader” or “heatsink” covering the slot. You’ll need to remove a small screw or two to take this cover off.

Important Note: Make sure you’re using the right slot. Some motherboards have multiple M.2 slots, but only one might be the “fast” one (e.g., PCIe 4.0). Check your manual! A good motherboard is key, as we discuss in our guide to choosing a gaming motherboard.

Step 3: Install the M.2 Drive

  1. At the end of the M.2 slot (opposite the connector), there is a tiny standoff and a screw. Your motherboard likely came with this in a small bag. If it’s already on the board, you may need to move the standoff to the correct hole (e.g., “2280,” which matches the length of most M.2 drives).
  2. Gently slide the M.2 drive into the slot at a slight upward angle (about 20-30 degrees). The gold connectors will disappear.
  3. Gently press the drive down so it lies flat against the standoff.
  4. Use your small screwdriver to secure the drive with the tiny M.2 screw. Do not overtighten! Just “snug” is perfect.
  5. If you removed a heatsink, re-install it now (making sure to remove any plastic film from the thermal pad first).

Part 5: After Installation – How to Initialize and Format Your New Drive

You’ve installed your drive, but when you boot up Windows, it’s not there! Don’t panic. This is normal. Your new drive needs to be formatted.

This is a crucial step in the guide to setting up a new SSD for gaming.

  1. Boot your PC, log into Windows.
  2. Right-click the Start Button and select “Disk Management”.
  3. Disk Management will open, and a pop-up should immediately appear: “Initialize Disk”.
  4. It will show your new drive (e.g., “Disk 2”). You’ll be asked to choose a partition style:
    • Always choose GPT (GUID Partition Table). It’s the modern standard. (MBR is for old, small drives).
  5. Click OK.
  6. Now, in the main window, find your new drive. It will say “Unallocated.”
  7. Right-click on the “Unallocated” space and select “New Simple Volume…”.
  8. A wizard will pop up. Just click “Next” through all the steps, accepting the defaults.
    • Assign Drive Letter: You can pick any letter you want (e.g., “G:” for Games).
    • Format: Make sure the File system is NTFS (the Windows standard).
    • Volume Label: Give it a friendly name, like “My Game Library.”
    • Make sure “Perform a quick format” is checked.
  9. Click “Finish”.

In about 10 seconds, your new drive will be formatted, and it will appear in “This PC” ready to use!

Part 6: Managing Your Game Library: How to Move Games to Your New Drive

Now for the fun part: filling it up. You don’t need to re-download everything. You can easily move your Steam games to another drive.

How to Move Steam Library to a New Drive

  1. Create a New Steam Library Folder:
    • In Steam, go to Settings > Storage.
    • At the top, click the “+” icon.
    • Select your new drive (e.g., “G:”) from the drop-down.
    • Click “Add” to create a new SteamLibrary folder on that drive.
  2. Move Your Games:
    • Still in the Storage menu, you’ll see your list of installed games.
    • Check the box next to the game(s) you want to move.
    • At the bottom, click “Move”.
    • Select your new library folder from the drop-down and click “Move.”
    • Steam will handle the entire file transfer. Do not just copy-paste the folder in Windows Explorer; this will break things.

How to Move Epic Games / GOG / Other Games

This can be trickier, but it’s getting easier.

  • Epic Games: The easiest way is to uninstall the game and simply reinstall it, selecting your new drive as the installation path.
  • GOG Galaxy: GOG has a “Manage Installation > Move” feature, similar to Steam’s.
  • EA App / Ubisoft Connect: Both platforms now allow you to change the “Installation” folder in their settings. Set this to your new drive.

For more detailed guides on moving specific libraries, you can often check the official support pages, like the Steam Support page on moving games.

Part 7: What About Your OS? Cloning vs. a Fresh Install

A very common question is: “I bought a new fast SSD. How do I move Windows to it?”

You have two options:

  1. Cloning (The “Easy” Way): This involves using software (like Macrium Reflect or Samsung Magician) to make an exact 1-to-1 copy of your old drive onto your new SSD. When it’s done, you swap the drives, and your PC boots up exactly as it was, just much faster.
    • Pros: You keep all your files, settings, and programs. It’s relatively fast.
    • Cons: It can sometimes copy over old errors or “digital junk.” It can be tricky if you’re moving from a large drive to a smaller one (e.g., 1TB HDD to 500GB SSD).
  2. Fresh Install (The “Clean” Way): This means installing a brand new, fresh copy of Windows onto your new SSD.
    • Pros: This is the cleanest possible start. Your PC will be incredibly fast and stable, with no old junk.
    • Cons: It takes time. You have to back up all your important files (photos, documents) and reinstall all your programs (Steam, Discord, etc.) from scratch.

Our Recommendation: If your current Windows install is more than 2-3 years old, do a fresh install. The performance boost is worth the one-time hassle. If your PC is relatively new and you just want the speed boost, cloning is a great option. If you’re new to this, check out Microsoft’s official guide on creating Windows installation media.

Part 8: Performance, RAM, and Your New Storage

Adding a fast SSD is one of the most noticeable upgrades you can make, but it’s part of a larger ecosystem. Your system’s performance is a balance.

  • Loading Times: This is where your SSD shines. It fetches game assets (textures, models, audio) and delivers them to your RAM and CPU.
  • RAM (Memory): Your RAM is the super-fast temporary workspace. The SSD loads the game into RAM, and your CPU pulls from RAM to show it on screen.

If you have a fast new NVMe SSD but only 8GB of slow RAM, your PC will still struggle! You’ve just moved the bottleneck. You need enough RAM to hold all the data your SSD is feeding. For most modern gaming, 16GB is the minimum, but 32GB is quickly becoming the new standard for high-end, modded, or future-proof builds.

This is a deep topic, and if you’re wondering if your RAM is holding you back, you should read this pillar post: 16GB vs 32GB RAM for Gaming: What Do You Really Need for a Budget Build? It’s the perfect companion piece to your new storage upgrade. A complete PC build involves balancing all these parts, which you can learn about in our ultimate PC build guide for beginners.

Frequently Asked Questions (FAQ)

1. Will adding more storage increase my FPS (Frames Per Second)?

No. Your FPS is determined by your Graphics Card (GPU) and, to a lesser extent, your CPU. A faster SSD will not give you more frames. However, it will drastically reduce or eliminate stuttering caused by the game trying to load assets from a slow drive.

2. What is the best size SSD for gaming in 2024?

1TB is the minimum we recommend for a new boot/game drive. 2TB is the sweet spot for price-to-performance, allowing you to install 10-15 large games. 4TB drives are becoming great options for enthusiasts who want their entire library on one fast drive.

3. Can I just use an external hard drive for my PC games?

Yes, you can. It’s the easiest method. You can install and play games directly from an external drive. An external SSD connected via USB 3.0 (or faster) will be a good experience. An external HDD will be slow, and you will have long loading times.

4. What’s the difference between a SATA SSD and an NVMe M.2 SSD for gaming?

In benchmarks, NVMe is 5-7x faster. In real-world game loading, the difference is much smaller. An NVMe might load a game in 7 seconds, while a SATA SSD loads it in 10 seconds (and an HDD in 60 seconds). Both are a huge upgrade. If you have an M.2 slot, go for NVMe. If not, a SATA SSD is still a fantastic choice.

5. How do I know if my motherboard has an M.2 slot?

The only 100% sure way is to check your motherboard’s manual or search for its exact model number online. Most motherboards made in the last 5-6 years have at least one.

6. My motherboard has a heatsink over the M.2 slot. Do I use it?

Yes! NVMe drives can get hot under heavy load. The heatsink (or “heat spreader”) helps dissipate that heat, preventing the drive from “throttling” (slowing down) to protect itself.

7. I installed my new drive, but it’s not showing up in Windows. What do I do?

You need to initialize and format it. Scroll up to “Part 5: After Installation” in this guide. This is the most common “problem” and is a normal part of the process.

8. Is it hard to install an SSD? I’m afraid I’ll break something.

It’s one of the easiest PC upgrades, often called “adult LEGOs.” If you can use a screwdriver and follow instructions, you can do it. Just remember to be gentle, shut off the power, and ground yourself.

9. Can I install two M.2 SSDs?

Maybe. Many mid-range and high-end motherboards have two or even three M.2 slots. Check your manual. You can absolutely use one for your OS and main programs, and a second one just for your game library.

10. What is a “DRAM-less” SSD and should I avoid it?

DRAM is a small, fast bit of cache on an SSD that helps it manage data. “DRAM-less” SSDs are cheaper because they skip this part. For a game-only drive, they are perfectly fine. For a boot drive (where Windows is installed), it’s highly recommended to get an SSD with DRAM for better performance.

11. How do I transfer my Windows 10/11 license to my new SSD?

If you are just adding a new drive (for games), you don’t do anything. If you are replacing your old drive with a new one and doing a fresh install, your Windows license is tied to your Microsoft account or your motherboard. It should reactivate automatically when you log in.

12. Is it safe to move my PC to install a drive?

Yes. Just be gentle. Don’t drop it or shake it violently. Laying it on its side on a table or carpet-free floor is the best way to work on it.

13. My new drive came with cloning software. Should I use it?

Yes. Drive manufacturers like Samsung, Crucial, and Western Digital provide excellent, free tools for cloning your old drive to your new one. They are often the most reliable way to do it.

14. SATA vs. NVMe vs. HDD: What should I buy?

  • New PC Build: 1TB NVMe M.2 SSD (for OS + main games) and a 2-4TB SATA SSD (for other games).
  • Upgrading a PC with an M.2 slot: Get a 1TB or 2TB NVMe M.2 SSD.
  • Upgrading an older PC (no M.2): Get a 1TB or 2TB SATA SSD.
  • Just need max cheap space: Get a 4TB HDD for archive/storage.

15. How long does an SSD last?

A very, very long time. Modern SSDs have a “lifespan” measured in Terabytes Written (TBW). For a typical 1TB gaming SSD, you would have to write and delete hundreds of gigabytes of data every single day for over five years to wear it out. For normal gaming, it will likely outlast every other part in your PC.
