Let’s be real for a second-the PS5’s internal storage fills up faster than you can say “download queue.” One minute you’re installing the latest blockbuster, the next you’re playing musical chairs with your game library, deleting old favorites to make room. It’s frustrating, and it kills the gaming vibe.
That’s where a proper storage expansion comes in, and the options can be downright confusing. Do you go for a super-fast internal SSD or a massive, budget-friendly external hard drive? I’ve been testing these drives in my own PS5 for months, and I’m here to cut through the noise. We’re going to look at the real-world performance, the installation headaches (or lack thereof), and figure out which solution is actually worth your hard-earned cash. No marketing fluff, just straight talk from a fellow gamer who’s been there.

Our Testing Process: Why These Rankings Are Different
Let’s be honest-most “best of” lists just parrot specs and Amazon stars. We did things differently. I personally tested a wide range of storage solutions in a real PS5, focusing on how they actually perform in your living room, not just on a spreadsheet.
Our scoring is based on a 70/30 split: 70% of the score comes from real-world factors like how well the drive matches PS5 use cases, the positivity of user experiences, and overall value. The remaining 30% rewards genuine innovation and competitive advantages, like official licensing or unique cooling solutions.
For example, our top-rated WD_BLACK SN850P scored a near-perfect 9.8 for its flawless compatibility and seamless performance. Compare that to our budget YOTUO external drive at 8.0-the score difference reflects the trade-off between bulletproof reliability and ultra-low cost.
We looked at everything from premium internal SSDs to massive external hard drives. The goal was to find the best tool for every job and budget, whether you’re a competitive gamer needing zero load times or a casual player just wanting more space. Our rankings are built on hands-on testing and real gamer needs, not marketing hype.
Complete Buyer's Guide: How to Choose Storage Expansion for Your PS5
1. Internal SSD vs. External Hard Drive: The Core Choice
This is the biggest decision you’ll make. An internal M.2 NVMe SSD (like our top picks) slots directly into your PS5. You can play both PS4 and PS5 games directly from it, and load times are incredibly fast. It’s the premium, integrated solution. An external USB hard drive is cheaper and plugs into a port. You can play PS4 games directly from it, but PS5 games must be copied back to the internal SSD to play-it’s better for archiving. Think of an SSD for active games and an HDD for your library.
2. Speed Matters: Understanding Read/Write Specs
For internal SSDs, look for PCIe Gen4 drives with read speeds of at least 5,500 MB/s to meet Sony’s recommendation. Drives like the WD_BLACK and Samsung hit 7,000+ MB/s, which translates to near-instant loading. For external HDDs, USB 3.0 is the standard, but speed is limited by the spinning disk-it’s fine for storage but slow for active play.
3. Capacity: How Much Space Do You Really Need?
Game sizes are huge. A 1TB SSD effectively doubles your PS5’s space, holding ~10-15 modern games. 2TB is the sweet spot for most, offering a great balance. 4TB is for collectors who never want to delete a game. For external HDDs, 2TB-8TB are common; they’re for bulk storage, so go as big as your budget allows.
4. The Heatsink Requirement (Non-Negotiable for Internal)
The PS5’s M.2 slot is tight and gets hot. You must use an SSD with a heatsink. Many drives come with one pre-installed (highly recommended). If not, you’ll need to buy and attach a compatible third-party heatsink separately-it’s a hassle you can avoid.
5. Compatibility & Official Licensing
Any Gen4 SSD meeting the speed requirement should work, but officially licensed drives (like the WD_BLACK SN850P or Seagate Game Drive) guarantee compatibility and often have optimized heatsinks. Non-licensed drives from reputable brands (Samsung, WD_BLACK SN850X) work flawlessly 99% of the time but lack that formal guarantee.
6. Installation: How Hard Is It Really?
Installing an internal SSD is surprisingly easy. You remove one PS5 side panel, unscrew one cover, slot in the drive, screw it down, and replace the panel. The console guides you through formatting. It takes 5-10 minutes. External drives are literally plug-and-play-the easiest option by far.
Frequently Asked Questions
1. Can I play PS5 games directly from an external hard drive?
No, you cannot. Due to the speed requirements of PS5 games, they must be run from the console’s internal SSD or an installed internal M.2 SSD. You can store PS5 games on an external USB hard drive, but to play them, you must first copy them back to the fast internal storage. This is still much faster than re-downloading them.
2. How do I install an internal SSD in my PS5?
It’s a straightforward process. First, turn off and unplug your PS5. Remove the stand and then the white side panel (the one away from the disc drive if you have it). You’ll see a rectangular metal cover with a screw. Remove that, align the notch on your M.2 SSD with the slot, insert it at a slight angle, press down, and secure it with the provided screw. Replace the cover and side panel, power on, and your PS5 will prompt you to format the new drive. There are many great video tutorials online if you’re a visual learner!
3. What's the difference between "officially licensed" and "compatible" SSDs?
An officially licensed SSD (like the WD_BLACK SN850P) has been formally tested and approved by Sony. It’s guaranteed to work perfectly with all PS5 models and often comes with a heatsink designed specifically for the console’s dimensions. A compatible SSD meets the published technical requirements (Gen4, minimum speed) and will almost certainly work, but it hasn’t gone through Sony’s formal certification process. In practice, both work well, but the licensed option offers maximum peace of mind.
4. Will adding an internal SSD void my PS5 warranty?
No, it will not. Sony explicitly designed the PS5 with a user-expandable M.2 slot. As long as you use a compatible drive and don’t physically damage the console during installation, your warranty remains completely intact. This is a supported and encouraged upgrade.
5. Is it worth getting a 4TB SSD, or is 2TB enough?
This totally depends on your gaming habits. If you like to keep a massive library of 30+ games installed and ready to play at all times, a 4TB drive is a fantastic (if expensive) luxury. For most gamers, a 2TB drive is the perfect sweet spot. It comfortably holds your current favorites, a few large live-service games, and a backlog, without forcing constant management. Start by calculating the total size of the games you must have installed, then add 30% for future updates.
Final Verdict
So, what’s the final call? If you want the absolute best, no-compromise experience and money is no object, the officially licensed WD_BLACK SN850P is your drive. For the best blend of killer performance and smart value, the WD_BLACK SN850X is incredibly hard to beat. And if you just need a cavernous place to dump your entire game library for the lowest cost, the Avolusion 8TB external HDD has you covered. No matter your budget or play style, there’s a perfect storage expansion here that will finally let you stop deleting games and start playing them.
