Adding Extra Storage to a Mac: The Pros and Cons of Upgrading Internal SSD

While many users aspire to add more storage to their Mac, the reality depends largely on the model year. As discussed below, certain models, such as the 2015 and later MacBook Air and MacBook Pro, are equipped with onboard soldered SSDs, making additional storage installations challenging or impossible—unless you're planning to use an external HDD. This article explores the pros and cons of upgrading your Mac's internal storage and the options available for those looking to expand their Mac's storage capacity.

Model-Specific Considerations

Starting with the most recent models, Apple has moved away from user-upgradable components, including SSD storage. Most post-2012 Macs are designed to be non-user-serviceable, which means you cannot install additional storage devices without opening the Mac and soldering a new SSD—something that is generally not recommended due to potential risks and complexity.

A prime example is the 2019 MacBook Pro 13-inch model, which comes with a 120GB SSD. While you can use 1TB external HDDs to supplement your storage needs, integrating this into the Mac itself is not possible. The lack of replacement options for your internal SSD means you might need to replace the entire logic board if something goes wrong.

Advantages of Soldered SSD

Despite the limitations, the advantages of a soldered SSD are significant. A soldered SSD is faster than external SSDs or replaceable SSDs. This is because soldered SSDs are directly connected to the motherboard, eliminating any potential I/O bottlenecks that an external SSD might introduce. Additionally, the design is more compact, fitting within the space constraints of the device without compromising on efficiency.

Disadvantages of Non-Upgradable SSD

The primary disadvantage of having a non-upgradable SSD is the inability to replace it after installation. If the SSD fails, you might need to replace the entire logic board, which can be costly and time-consuming. This issue highlights the importance of backing up your data regularly and being aware of potential risks associated with your SSD's lifecycle.

Using External HDD for Storage

A workaround for those who cannot upgrade the internal SSD is to use an external HDD. Most modern Macs do not have the option to add built-in storage, as the internal space is already maximized for the original components. Even if your model supports additional storage, you might need to specifically check the specifications and documentation to be sure.

Converting your 1TB internal HDD to an external HDD using an enclosure is a viable solution. This allows you to access your data from anywhere, expand your storage capacity, and keep your original Mac functional. The key is to choose a reliable external HDD with a sturdy enclosure to ensure optimal performance and longevity.

Conclusion

In conclusion, while adding extra storage to your Mac is not always straightforward, it is possible with external solutions. The desire for more storage often needs to be balanced against the practical limitations of the Mac model you are using. Whether you opt for a reliable external HDD or consider the potential upgrade options for newer models, staying informed about your Mac's storage capabilities can help you make the best decision for your needs.
