LaCie 4TB 2big USB 3.0 Hard Drive Array, 5400 RPM Rotation Speed, PC, Mac

The LaCie 4TB 2big USB 3.0 is the ultimate approach to a flexible RAID (Redundant Array of Independent / Inexpensive Disks) solution, with its ability to manage various RAID levels for a wide range of applications.

Since needs differ among all users, the LaCie 2big USB 3.0 allows you to choose between faster transfer rates or file mirroring with a simple flip of a switch. For high-speed demanding programs, such as video editing or graphics, you may choose RAID 0 (fast). If data backup is important, RAID 1(safe) will keep a copy of each file on the 2big's two disks. Providing greater integrity and validation than standard hard disk storage, RAID technology is one of the best means to protect your data. With the USB 3.0 interface, you will experience enhanced transfer rates to complement whatever RAID level you choose.

Its solid aluminum casing provides 60% more surface area, which dissipates heat more efficiently. In addition, it's thermo-regulated fan turns on and off according to internal temperature. As a result, it cools the components while reducing electricity usage.
