Is It Better to Play Games on External SSD or Internal HDD? The Definitive Answer

The simple answer is a resounding no, it is almost always better to play games on an internal SSD than an external SSD or an internal HDD. While an external SSD is preferable to an internal HDD, the internal SSD generally provides the best balance of speed, latency, and overall gaming performance for most setups. Let’s delve into the nuances of why this is the case, exploring the technology behind each option and weighing the pros and cons.

The Battle of Storage Technologies: SSD vs. HDD

To understand why an internal SSD reigns supreme, it’s crucial to grasp the fundamental differences between Solid State Drives (SSDs) and Hard Disk Drives (HDDs).

Hard Disk Drives (HDDs): The Reliable Workhorse

HDDs are the veterans of the storage world. They store data on spinning magnetic platters, and a read/write head accesses the data as the platter rotates. This mechanical process has inherent limitations. Accessing data requires the head to physically move to the correct location on the platter, introducing latency (delay). Key characteristics of HDDs include:

Affordability: HDDs offer the lowest cost per gigabyte of storage.
High Capacity: HDDs are available in very large capacities, often exceeding several terabytes, making them suitable for storing vast game libraries.
Slower Speeds: Due to the mechanical nature, HDDs have slower read and write speeds compared to SSDs.
Vulnerability to Damage: Because of the moving parts they are more susceptible to damage from shock or vibration.

Solid State Drives (SSDs): The Speed Demon

SSDs, on the other hand, utilize flash memory to store data electronically. They have no moving parts, which translates to significantly faster access times and increased durability. Key characteristics of SSDs include:

Faster Speeds: SSDs boast significantly faster read and write speeds compared to HDDs, drastically reducing loading times.
Lower Latency: The absence of moving parts results in lower latency, leading to quicker response times.
Increased Durability: SSDs are more resistant to shock and vibration due to the lack of mechanical components.
Higher Cost: SSDs are generally more expensive per gigabyte than HDDs.

Internal SSD vs. External SSD: A Closer Look

While both are SSDs and offer benefits over HDDs, internal and external SSDs differ in connection type and potential speed.

Internal SSDs: The Optimal Choice

Internal SSDs connect directly to your motherboard using interfaces like SATA III or NVMe (via PCIe). NVMe SSDs, in particular, offer the highest performance, leveraging the speed of the PCIe bus for lightning-fast data transfer. Key advantages of Internal SSDs:

Maximum Performance: When connected via NVMe/PCIe, internal SSDs achieve the highest possible read/write speeds.
Lower Latency: The direct connection minimizes latency.
Optimized for Gaming: Designed for demanding applications like gaming.

External SSDs: The Portable Solution

External SSDs connect to your computer via USB ports. While USB technology has improved, it still introduces overhead and limitations compared to internal connections. Key considerations for External SSDs:

Portability: Easily transferable between devices.
Convenience: Simple plug-and-play setup.
Speed Limitations: USB connections, even USB 3.2 Gen 2×2 or Thunderbolt 3/4, have limitations.

Understanding USB Standards and Speeds

It’s crucial to understand USB connection types as they affect the speed of your external SSD. USB 3.0 and above offer significantly improved speeds compared to older standards such as USB 2.0, but there are still noticeable speed differences between USB 3.0, USB 3.1, USB 3.2, and USB4, which can vary widely depending on the specific implementation and the host controller.

Why Internal SSDs Excel for Gaming

Games benefit immensely from the speed and low latency of SSDs. Specifically:

Faster Loading Times: Games launch much faster, and level loading times are drastically reduced. This means less waiting and more gaming.
Smoother Gameplay: Games that stream assets from storage, such as open-world titles, experience fewer stutters and pop-in textures when installed on an SSD.
Improved System Responsiveness: The operating system and other applications also benefit from the speed of an SSD, resulting in a snappier and more responsive system.

When External SSDs Might Be a Viable Option

While internal SSDs are generally preferred, there are scenarios where an external SSD might be a reasonable choice:

Limited Internal Storage: If your internal storage is full, an external SSD can provide additional space for games.
Portability: If you frequently move your game library between computers or consoles, an external SSD offers a convenient solution.
Console Gaming: External SSDs can significantly improve loading times on consoles.
Specific USB Configurations: Connecting the external SSD directly to the best USB Port on your machine, (i.e. fastest transfer rate).

Important Note: Ensure your external SSD and USB port support the latest USB standards (USB 3.2 Gen 2×2 or Thunderbolt 3/4) to maximize performance. Even then, you won’t get as fast as the internal SSD, because the USB Controller on the external SSD and your Motherboard Controller add a bit of latency and overhead.

Internal HDD: Last Resort?

While HDDs offer ample storage and affordability, they are the least desirable option for gaming in most cases. The slow loading times and potential for stuttering can significantly detract from the gaming experience. The exception would be if you have a very large library of games that you rarely play, and don’t mind longer loading times to save money.

Conclusion: Internal SSD for the Win!

For the best gaming experience, an internal SSD is the clear winner. Its speed, low latency, and direct connection provide optimal performance. While external SSDs can be a viable alternative in certain situations, they are generally not as performant as internal SSDs due to the limitations of USB connections. Ultimately, the choice depends on your specific needs and budget, but prioritizing an internal SSD will almost certainly elevate your gaming experience.
