Does HDD Slow Down Your PS5? The Truth About Storage Performance
Yes, using an HDD (Hard Disk Drive) as your primary storage or even as storage for frequently accessed data will significantly slow down your PS5 compared to using its internal SSD (Solid State Drive). The PS5’s architecture is built around the incredibly fast read/write speeds of its internal SSD, and relying on an HDD creates a massive bottleneck, especially for PS5 games. While HDDs can be useful for specific purposes like storing PS4 games, understanding their limitations is crucial for optimizing your gaming experience.
Understanding the PS5’s Storage Architecture
The PlayStation 5 was designed with speed in mind. Its developers invested heavily in a custom NVMe SSD and a sophisticated architecture to leverage the performance benefits. This means faster loading times, quicker in-game asset streaming, and an overall more responsive gaming experience.
- Internal SSD: This is the PS5’s primary storage and where you should install your PS5 games for optimal performance.
- M.2 SSD Expansion Slot: The PS5 allows you to add an additional internal NVMe SSD to expand your storage capacity and maintain high performance.
- External HDD/SSD via USB: You can connect external drives via USB, but their functionality is limited. You can play PS4 games directly from an external drive. PS5 games can only be stored on external drive and need to be transferred to the internal SSD before they can be played.
The HDD Bottleneck
The core issue with using an HDD for anything beyond archival storage on a PS5 is the significant difference in speed compared to an SSD. HDDs rely on spinning platters and a mechanical arm to read and write data, which is inherently slower than the flash memory used in SSDs.
- Slower Load Times: This is the most noticeable impact. Games will take significantly longer to load levels, start up, and transition between areas.
- Reduced In-Game Performance: The PS5 streams game assets (textures, models, etc.) from storage in real-time. A slow HDD can lead to stuttering, pop-in (where objects appear suddenly), and a general lack of responsiveness.
- OS Responsiveness: Even navigating the PS5’s operating system can feel sluggish when the system relies on an HDD for essential files.
When HDDs Are (Still) Useful
Despite the performance drawbacks, HDDs still have some limited applications with the PS5:
- PS4 Game Storage and Playback: You can store and play PS4 games directly from an external HDD connected to your PS5. Since PS4 games were designed for slower HDDs, the performance impact is less noticeable.
- PS5 Game Archiving: You can store PS5 games on an external HDD to free up space on your internal SSD. However, you’ll need to transfer the games back to the internal SSD before you can play them. This is essentially a way to archive games you’re not currently playing.
- Cost-Effectiveness: HDDs offer more storage per dollar than SSDs, making them a budget-friendly option if you need a lot of storage for PS4 games or archiving PS5 titles.
SSD vs. HDD: A Head-to-Head Comparison
| Feature | SSD | HDD |
|---|---|---|
| —————– | ——————————————————————– | ————————————————————————– |
| Speed | Significantly faster read/write speeds (5500 MB/s or higher) | Slower read/write speeds (typically 50-150 MB/s) |
| Loading Times | Much faster game loading and level transitions | Significantly longer loading times |
| Performance | Smoother gameplay, reduced stuttering and pop-in | Potential for stuttering, pop-in, and reduced responsiveness |
| Durability | More durable (no moving parts) | More susceptible to damage from physical shock |
| Cost | More expensive per gigabyte | Less expensive per gigabyte |
| Best Use on PS5 | PS5 game installation and play, demanding PS4 games | PS4 game storage and play, PS5 game archiving |
Optimizing Your PS5 Storage
Here’s how to get the best storage performance from your PS5:
- Install PS5 games on the internal SSD or an M.2 SSD. This is crucial for optimal performance.
- Use an external HDD for PS4 games. This allows you to play PS4 games without sacrificing the performance of your PS5 games.
- Consider an M.2 SSD upgrade. If you run out of space on your internal SSD, an M.2 SSD is the best way to expand your storage without compromising performance. Make sure to check Sony’s website for the full spec list before buying a new drive.
- Manage your storage effectively. Delete games you’re not playing to free up space on your internal SSD.
- Regularly back up your game saves. This protects your progress in case of a storage failure.

Frequently Asked Questions (FAQs)
1. Can I play PS5 games directly from an external HDD?
No, you cannot play PS5 games directly from an external HDD. You can store them there, but you’ll need to transfer them back to the internal SSD or an installed M.2 SSD before you can play them.
2. Will an external SSD improve PS4 game performance on my PS5?
Yes, using an external SSD for PS4 games will generally improve loading times and potentially reduce stuttering compared to using an external HDD.
3. Is it better to upgrade the internal storage or use an external drive for my PS5?
Upgrading the internal storage with a compatible M.2 SSD is generally the better option, as it provides the best performance for both PS5 and PS4 games. External drives are primarily useful for storing PS4 games and archiving PS5 games.
4. What type of external hard drive is best for my PS5?
For storing and playing PS4 games, a standard USB 3.0 HDD is sufficient. If you want faster loading times for PS4 games, consider an external SSD connected via USB 3.0 or higher.
5. How much storage do I need for my PS5?
This depends on how many games you play. The internal drive is around 825GB with only around 667GB usable. If you play a lot of large games, a 1TB or 2TB M.2 SSD upgrade is recommended.
6. Does a full SSD slow down my PS5?
Modern SSDs are designed to maintain performance even when nearly full. While copying data may be slightly slower, loading games shouldn’t be significantly affected.
7. What is the minimum read/write speed for a PS5-compatible M.2 SSD?
The minimum read/write speed for a PS5-compatible M.2 SSD is 5500 MB/s.
8. Can I use any M.2 SSD in my PS5?
No, you can’t use just any M.2 SSD. It needs to meet Sony’s specifications, including the correct form factor, interface (PCIe Gen4 x4 NVMe), and read/write speeds. Always check Sony’s compatibility list before purchasing.
9. How many PS5 games can a 1TB SSD hold?
This depends on the size of the games, but typically, a 1TB SSD can hold around 15-25 PS5 games. Modern games now require larger storage spaces.
10. Can I use a USB hub to connect multiple external drives to my PS5?
Yes, you can use a USB hub, but it’s recommended to use a powered USB hub to ensure sufficient power for all connected devices. Performance may be affected if the hub shares bandwidth between devices.
11. Will an HDD cause my PS5 to overheat?
While an HDD itself is unlikely to cause overheating, poor ventilation around the console can lead to overheating issues. Ensure your PS5 has adequate airflow regardless of the storage you’re using.
12. Is it okay to leave an external HDD connected to my PS5 all the time?
Yes, it’s generally okay to leave an external HDD connected, but it’s recommended to safely eject the drive through the PS5’s settings before physically disconnecting it.
13. What happens if I try to play a PS5 game directly from an HDD?
If you try to launch a PS5 game that’s stored on an external HDD, the PS5 will prompt you to move the game to the internal SSD or an installed M.2 SSD before you can play it.
14. Can I install PS4 games on the PS5’s internal SSD?
Yes, you can install PS4 games on the PS5’s internal SSD. This will generally result in faster loading times compared to playing them from an external HDD.
15. How do I move PS5 games between the internal SSD and an external HDD?
You can move PS5 games between the internal SSD and an external HDD through the PS5’s storage settings. Navigate to Settings > Storage, select the drive you want to move games from, and then choose the games you want to transfer.
