External SSDs vs Internal SSDs: Which Is Faster?

If you’re looking to upgrade your storage solution, you may be wondering what the difference is between an external SSD and an internal SSD. While both offer fast read/write speeds, there are certain factors that can make one better than the other depending on your needs. Read on to find out which one is faster and why!


When it comes to speed, there is no clear winner between external and internal SSDs. However, there are some important factors to consider when choosing between the two. Internal SSDs are typically faster than external SSDs, but they can be more expensive and difficult to install. External SSDs are usually more affordable and easier to install, but they can be slower than internal SSDs.


What is an External SSD?

An external SSD is a type of solid state drive that connects to a computer via a USB port. External SSDs are typically smaller in size than internal SSDs and offer faster data transfer speeds. They also tend to be more expensive than internal SSDs.

What is an Internal SSD?

An internal SSD is a type of solid-state drive that is designed to be installed inside a computer. Internal SSDs typically come in the form of a 2.5-inch drive, which is the same size as a traditional hard drive. However, unlike hard drives, internal SSDs have no moving parts and instead rely on flash memory to store data. This means that internal SSDs are much faster and more reliable than hard drives.

Advantages and Disadvantages of External SSDs

External SSDs offer a number of advantages over internal SSDs. They are typically smaller and more portable, making them ideal for use with laptops and other mobile devices. They also tend to be less expensive than internal SSDs, making them a good option for budget-conscious consumers. However, external SSDs have some disadvantages as well. They are usually slower than internal SSDs, and they can be more susceptible to damage from drops and other physical impacts.

Advantages and Disadvantages of Internal SSDs

External SSDs offer many advantages over internal SSDs, including faster data transfer rates, portability, and ease of use. However, there are also some disadvantages to using an external SSD, including potential compatibility issues and the need for an adapter.

Internal SSDs offer several advantages over external SSDs, including lower costs, higher data capacities, and better performance. However, there are also some disadvantages to using an internal SSD, including the need for installation and the risk of data loss if the drive fails.

Which is Faster: External SSDs or Internal SSDs?

External SSDs are typically much faster than internal SSDs. This is because external SSDs can take advantage of the much higher data transfer speeds that are available on the latest generation of USB 3.0 and Thunderbolt interfaces.

Internal SSDs, on the other hand, are limited by the slower data transfer speeds of the SATA interface. So, if you’re looking for the fastest possible data transfer speeds, an external SSD is the way to go.


In conclusion, external SSDs and internal SSDs both have their advantages and disadvantages when it comes to speed. External SSDs tend to be faster than their internal counterparts, but they also come with a few drawbacks such as size limitations and the potential for data loss if not properly disconnected from your device. Internal SSDs can offer higher capacity sizes while being more secure against data loss; however, they are usually slower due to lower read/write speeds. Ultimately, it is up to you to decide which type of storage best fits your needs based on speed and other factors.
