The Good The LaCie 2big USB 3.0 is fast, has a great design, and includes a PCI-e USB 3.0 add-in card. It's extremely easy to change the drive from one RAID configuration to another.
The Bad The 2big is rather bulky and comparatively expensive.
The Bottom Line The LaCie 2big USB 3.0 is an overall excellent external hard drive.
If the recently reviewed LaCie Minimus is arguably the most compact desktop external hard drive, the LaCie 2big USB 3.0 is quite the opposite. It's huge and heavy. But that's the only complaint we have. The drive comes in a good-looking and user-friendly design. It's fast in our tests and incorporates a convenient way to manage the internal hard drives. If you're in need of an external hard drive to either expand your desktop computer's storage or store backups of important files, look no further than the LaCie 2big USB 3.0. At the street price of around $330 for 2TB (or $550 for 4TB), the 2big is slightly more expensive than other similarly configured external hard drives of the same specs, but it's well worth the investment.
Design and features
The LaCie 2big USB 3.0 is the first USB 3.0-based external hard drive that supports RAID we've reviewed. It can host two 3.5-inch SATA internal hard drives and allows you to configure them into either RAID 1 (for data protection) or RAID 0 (for maximum storage space and speed). You can also use the two hard drives in a non-RAID setup called JBOD.
