10 Best External Hard Drive For Macs 2025 in the United States

The LaCie d2 Professional 16TB External Hard Drive is an excellent choice for Mac users who need substantial storage capacity. With 16TB of space, it can store vast amounts of data, making it perfect for professionals dealing with large files such as video editors or photographers. The USB 3.1 Gen 2 interface ensures quick data transfer rates up to 260MB/s, which helps in accessing and moving files efficiently.

However, it's worth noting that this drive is designed primarily for desktop use due to its size and the need for an external power supply, which limits its portability compared to smaller, bus-powered drives. Its mechanical hard disk form factor means it may not be as fast as solid-state drives (SSDs) but offers a reliable solution for high-capacity storage needs. Compatibility with both PC and Mac is a strong point, making it versatile for users who operate across different platforms. The sturdy build and professional design add to its durability, making it a dependable option for long-term use.

While it excels in storage capacity and data transfer rates, its lack of portability and reliance on an external power source could be drawbacks for users seeking a mobile storage solution.

The SAMSUNG T9 Portable SSD 4TB is a solid choice for Mac users seeking high-speed, reliable external storage. With a substantial 4TB storage capacity, it provides ample space for large files and extensive data backups. The SSD uses a USB 3.2 Gen 2x2 interface, offering impressive read and write speeds of up to 2,000MB/s, making it suitable for tasks requiring fast data transfer, such as video editing and gaming. Its solid-state drive type ensures better durability and faster performance compared to traditional hard drives.

The T9 is also highly portable, measuring just 3.46 x 2.36 x 0.55 inches and weighing only 4.3 ounces, making it easy to carry around. It's compatible with a wide range of devices, including Macs, PCs, gaming consoles, and even iPhones, enhancing its versatility. The drive’s durability is further underscored by its rugged design, capable of withstanding drops up to 9.8 feet, and the inclusion of Dynamic Thermal Guard technology to manage heat during extended use.

However, its high-end performance comes at a premium price, which might be a consideration for budget-conscious users. Additionally, while the USB 3.2 Gen 2x2 interface offers excellent speed, users need to ensure their devices support this interface to fully benefit from the speed. Finally, while the drive’s encryption and Magician Software for firmware updates and drive health monitoring are great features, they might be more than what a casual user needs. Nevertheless, for professionals, gamers, and students who require robust, high-speed storage with excellent durability and compatibility, the SAMSUNG T9 Portable SSD 4TB is a commendable option.

The Seagate Expansion Desktop 14TB external hard drive is a robust option for anyone needing substantial storage capacity. With 14TB of space, it easily accommodates large files and extensive media libraries, making it highly suitable for professionals and media enthusiasts. The USB 3.0 interface ensures that data transfers are relatively quick, which is convenient for transferring large files.

While the name suggests portability, the product dimensions (7.04 x 1.65 x 4.92 inches) and weight (2.59 pounds) make it more suitable as a stationary desktop solution rather than something you'd carry around frequently. It is compatible with both Macs and PCs, adding to its versatility.

The included 2-year rescue service provides additional peace of mind in case of data recovery needs. However, its size and weight could be a drawback if you're looking for a truly portable solution. This hard drive is a solid choice for those who need a high-capacity, reliable external storage solution for desktop use.
