How to make a laptop run faster with external storage
10 oct., 2025
Few frustrations hit harder than waiting on a sluggish laptop. Whether you’re launching apps, opening files, or loading games, those wasted seconds add up fast. And unlike desktops, laptops often suffer more from these slowdowns due to their compact design and limited upgrade options.
Many users try the usual fixes — like clearing out files, running maintenance tools, even reinstalling the OS — only to find performance barely improves. That’s because the problem often isn’t software at all. It’s your storage bottlenecking your system’s performance.
Storage plays a bigger role in laptop speed than most people realize. The type of drive you’re using, its transfer speeds and its available capacity can all impact performance. The wrong setup leaves your CPU and GPU waiting in line, your load times dragging and your multitasking grinding to a halt.
The good news? There’s a simple, powerful solution. By adding external storage, you can bypass built-in limitations, free up system resources and accelerate your laptop’s overall performance without cracking it open or spending big on internal upgrades.
When people evaluate laptop performance, they often look at processors, graphics cards or memory. Yet one essential component frequently gets overlooked: storage device. It may seem like the only question is, “Do I have enough space?” But the type of storage you use and how well it’s built directly impacts your system’s speed, efficiency and reliability.
Your laptop relies on storage for nearly every task it performs. A strong drive means faster boot times, smoother application launches and quicker access to files. On the other hand, underpowered or limited storage can hold back even the most advanced CPU or GPU. Common signs of storage-related slowdowns include:
Hard drives remain a cornerstone of high-performance computing thanks to their unmatched balance of speed, reliability and longevity. Built on decades of refinement, hard drives offer enormous capacity for large files, consistent performance over time and the durability to support years of everyday use. For users who need dependable storage without compromise, they provide a proven, trusted solution.
Even with routine maintenance, laptops can run into performance issues tied to storage. The most common challenges include:
Adding to the challenge, many modern laptops are designed with sealed cases or soldered components, making internal upgrades increasingly difficult or even impossible.
The good news? You don’t have to replace your system to regain speed and capacity. With a Seagate external hard drive or external SSD, you can expand storage instantly, boost overall performance and extend the life of your laptop, all with the reliability and longevity Seagate hard drives are known for.
Whatever the root cause of the storage-dependent slowdowns, external storage technology from Seagate can help address the issue. Seagate offers various external hard drives and external SSDs that will help improve your laptop’s performance.

Expand your world with Seagate external drives
Performance gains vary. External storage will not accelerate your laptop’s processor or applications, but it can substantially improve file transfer and backup speeds. The form factor also impacts transfer speeds.
For example, the LaCie d2 Professional offers transfer rates up to 290 MB/s, and the One Touch External SSD provides transfer rates of up to 1,030MB/s. Actual results depend on your laptop’s interface and workload.
While you would still want your OS running from internal storage, it’s entirely feasible to run almost anything else from an external drive. Your primary hurdles here will be the speed of the external drive itself, and the max transfer speed of the connection — the port and the cable can be a major bottleneck if you’re not careful. With the right drive and the right connection, though, you can likely run all but the most demanding of applications from the external drive. |

All other things being equal, SSDs are capable of much higher transfer speeds than HDDs. Modern hard drives are by no means slow, reaching speeds as high as 550MB/s with premium options. Cutting-edge SSDs, however, can exceed speeds of 7,000MB/s. Bear in mind that this comes with a trade-off: HDDs offer more value in GB/TB of storage per dollar, often drastically so. |

Your primary considerations when selecting an external drive are capacity needs, speed requirements, budget limitations, and compatibility concerns. While there are other factors to keep in mind, those four will largely determine whether or not the drive you pick will meet your most critical needs, with compatibility and budget often being less flexible than the other two. |

Many of the external drives in our lineup are cross-compatible with a variety of device and OS types. That said, some are designed with narrower compatibility to optimize for a given implementation.
Some will be limited by which ports/connection types they are compatible with. And even if everything else is in the green, switching between different device and OS types will require formatting the drive properly to ensure things operate smoothly.
