LaCie vs Avolusion Drive Specs
Storage Capacity
The LaCie 2big Triple provides 2 TB of total storage across its two removable SATA drives. This model is designed for users who need RAID configurations, specifically RAID 1 for redundancy or RAID 0 for speed. In contrast, the Avolusion PRO-T8 offers a massive 14 TB of raw capacity. After formatting on a Windows OS, you get approximately 12 TB of usable space. For anyone needing to store large video libraries, extensive photo archives, or massive datasets, the Avolusion drive provides significantly more room for your files than the smaller LaCie unit.
Hardware Interface
Connectivity options differ sharply between these two drives. The LaCie 2big Triple supports FireWire 800, FireWire 400, and Hi-Speed USB 2.0. This multi-interface approach helps users with older Macs or legacy equipment that may not have modern ports. The Avolusion PRO-T8 relies solely on a USB 3.0 interface. While it lacks the legacy FireWire support, USB 3.0 offers faster data transfer rates for modern Windows PCs and laptops. You must check your computer's available ports to ensure compatibility, as the LaCie may require adapters for newer systems while the Avolusion fits standard modern USB slots.
Rotational Speed
The internal mechanics of the drives are not identical. The Avolusion PRO-T8 utilizes an enterprise-grade internal hard drive with a rotational speed of 7200 RPM. This higher speed can contribute to faster data access times and improved performance for demanding tasks. The LaCie 2big Triple specifications do not list the rotational speed of its two internal SATA drives. Without this data point, you cannot directly compare the raw seek times or sustained transfer rates. However, the Avolusion explicitly states its 7200 RPM rating, suggesting a focus on performance for its single-drive architecture.
Form Factor and Portability
Size and weight play a role in where you place these drives. The LaCie 2big Triple is a dual-bay unit measuring 6.7 inches wide, 3.5 inches high, and 7.8 inches long. It weighs 5.73 pounds and features a metal heat sink design for natural cooling. The Avolusion PRO-T8 is a single-bay desktop drive measuring 1 inch high, 4 inches wide, and 6 inches long. It weighs only 2 pounds. The Avolusion is more compact and lighter, making it easier to fit in tight spaces or move around. The LaCie is a heavier, bulkier unit designed for permanent desktop placement.
Compatibility
Operating system support varies between the two models. The Avolusion PRO-T8 is explicitly designed to work with any Windows OS desktop PC or laptop. It is formatted and optimized for the Windows environment. The LaCie 2big Triple does not list specific OS compatibility in its provided specifications, though its FireWire and USB interfaces are standard. You should verify if the LaCie drive includes drivers for your specific version of Windows or if it is better suited for macOS systems given its legacy FireWire ports. For a plug-and-play Windows experience, the Avolusion is the clearer choice based on the data.
Which LaCie or Avolusion Drive Fits You
Users needing RAID redundancy and multiple interfaces
The LaCie drive supports hardware RAID 1 with auto-rebuild, protecting your data if one drive fails. It also includes FireWire 800 and FireWire 400 ports alongside USB 2.0, offering flexible connectivity options for older systems or specific professional workflows that require legacy interface support.
Those requiring high capacity for Windows backups
The Avolusion drive provides 14 TB of storage, significantly more than the LaCie model. It uses a USB 3.0 interface for faster data transfers and includes a 7200RPM enterprise-grade drive. This setup is ideal for expanding desktop storage and performing daily scheduled backups on Windows systems.
Buyers prioritizing portability and lower weight
The Avolusion unit weighs only 2 pounds and measures 1 inch in height, making it much lighter and slimmer than the LaCie drive. Its compact desktop form factor allows for easy placement on a desk without taking up significant space, unlike the heavier, larger LaCie enclosure.
