These alternatives provide distinct features while maintaining the desktop form factor and substantial storage capacity you likely need for your primary drive.
Our top pick: Seagate Expansion 16TB Desktop Hard Drive with Hub.
How each alternative compares
LaCie 1big Dock 24TB Thunderbolt 3 Desktop Hard Drive
The LaCie 1big Dock offers 24TB of storage, which is significantly larger than the 16TB Seagate Expansion. It uses Thunderbolt 3 for faster data transfers, a major upgrade from the Seagate’s USB 3.0 interface. This drive also functions as a docking station with card readers, benefiting video professionals who need to ingest footage directly. However, it is much larger and heavier than the Seagate unit. You should choose this if you need maximum capacity and speed for creative workflows rather than simple desktop storage.
Avolusion PRO-T8 14TB External Desktop Hard Drive
The Avolusion PRO-T8 provides 14TB of storage, which is less than the Seagate Expansion’s 16TB. It features a 7200 RPM rotational speed, likely offering faster performance than standard desktop drives. The interface is USB 3.0, matching the Seagate. A key difference is that this drive is compatible with Windows only, whereas the Seagate works with both PC and Mac. It is a compact option for users who prioritize speed and Windows compatibility over the extra 2TB of capacity and cross-platform support found in the Seagate model.
Seagate Backup Plus Hub 4TB Desktop Hard Drive
The Seagate Backup Plus Hub has 4TB of storage, which is much smaller than the 16TB Expansion. It shares the USB 3.0 interface and desktop form factor. Like the Expansion, it includes a built-in USB hub for connecting peripherals. The main trade-off is capacity; you get less storage space. This drive is suitable if you do not need 16TB and prefer a smaller footprint. It also supports both PC and Mac, similar to the Expansion. Choose this if your data needs are modest and the integrated hub is your primary requirement.
Western Digital 4TB My Book Desktop Hard Drive
The Western Digital My Book offers 4TB of storage, significantly less than the 16TB Seagate Expansion. It uses USB 3.0 and supports both PC and Mac, just like the Seagate drive. It includes password protection for data security, a feature also present in the Expansion. The difference lies in capacity and brand ecosystem. You get far less storage with the WD drive. This option is best for users who need secure, single-PC backups and do not require the massive 16TB capacity or the additional USB hub functionality of the Seagate Expansion.
LaCie 2big Dock 8TB External RAID Drive
The LaCie 2big Dock provides 8TB of storage, which is half the capacity of the 16TB Seagate Expansion. It supports RAID configurations for data redundancy, a feature the Seagate Expansion lacks. It uses Thunderbolt 3 and USB-C for high-speed transfers, outperforming the Seagate’s USB 3.0. It also includes card slots for direct media ingestion. This drive is heavier and more complex. You should pick this if you value data protection and professional video workflows over raw storage capacity and simplicity.
LaCie Mobile Drive 2TB USB-C External HDD
The LaCie Mobile Drive has 2TB of storage, which is much smaller than the 16TB Seagate Expansion. It is designed for portability, with a compact size and USB-C connectivity. The Seagate Expansion is a desktop drive that requires a power outlet. This LaCie drive is bus-powered and easy to carry. It supports both PC and Mac. You should choose this if you need storage on the go rather than fixed desktop capacity. It sacrifices the 16TB volume and desktop hub for extreme portability and modern USB-C connectivity.
