8.0TB 2big Quadra USB 3.0

Mac / PC / USB 3.0 / FireWire 800 / RAID 0, 1
In this deadline-driven world, your external storage has to move data fast, be constantly dependable, and connect to any standard computer on the planet. With these needs in mind, LaCie designed the 2big Quadra USB 3.0 from the ground up. It features USB 3.0 and an even more efficient cooling system that is 50% quieter than previous generations. The LaCie 2big Quadra USB 3.0 is completely reliable and perfect for intensive content creation, secure backup, or massive desktop storage.
SuperSpeed USB 3.0 for a Workflow Boost
Now with USB 3.0 and UAS compatibility, the LaCie 2big Quadra delivers optimized performance for PC and Mac. Its two 7200rpm professional hard disks preconfigured in RAID 0 provide up to 210MB/s* on PCs or late-model Macs. The hardware RAID controller ensures sustained performance and prevents dropped frames. More than twice as fast as FireWire 800 (up to six times the speed of USB 2.0), the LaCie 2big Quadra will transform your workflow. And its massive capacity makes it the only storage you'll need for all your projects. Backups and file transfers finish much faster. Play back multiple HD video streams in Final Cut Pro X™ or Adobe®Premiere®. Enjoy more responsive photo library browsing in Aperture™ or Lightroom™.
Universal Connectivity for Compatibility
Don't let your project get derailed by external drive/computer incompatibility. With its multiple interfaces, the LaCie 2big Quadra is the perfect match for any Mac or PC. With FireWire 800, import your data from your old computer even faster, if your old computer is compatible. You can even daisy chain older external storage devices or A/V peripherals in order to import data directly, hassle-free. Thanks to backwards compatibility with USB 2.0 and FireWire 400**, you can literally connect the LaCie 2big Quadra to any standard computer of any era. Whatever the computer you use, the LaCie 2big Quadra has the right connection for it.
Comprehensive Data Protection
The LaCie 2big Quadra goes the extra mile to protect your data. It features RAID 1 and hot-swappable disks, so your data is kept safe even if a drive fails. Simply swap in a new disk without switching off the device. No downtime, and no data loss. You also won't lose any data if, during a file transfer, someone trips over the interface or power cable. The LaCie 2big Quadra's cable management system keeps all cables safely connected to the enclosure. This product is also a complete workstation backup solution. It includes professional backup software that lets you perform file-level and even system-level backup and restore. So you can create a full system backup that lets you boot your Mac directly from the product. It's also Time Machine™ and Windows 7 Backup compatible. It even lets you prevent physical theft thanks to Kensington® lock compatibility.
Dual Cooling System for Long-Term Reliability
Since effective cooling is a critical factor in hard disk reliability, LaCie completely redesigned its 2big enclosure's cooling system. It ensures long-term reliability by preventing overheating. The system consists of three key components: an innovative heat-dissipating aluminum casing, a completely redesigned fan, and jumbo heat exhausts. For the enclosure, its solid-aluminum heat sink design provides 60% more surface area than flat designs, diverting and dissipating heat more efficiently. Its new magnetic levitation fan generates zero vibration or friction.

It pulls heat away from the internal components while being 50% quieter than previous generations. The fan is also thermo-regulated, so it controls its speed according to the ambient temperature. This means it works more efficiently, prolonging its lifespan and generating less noise. The 2ig Quadra has more and larger air holes to facilitate airflow and reduce noise. This ultra-quiet cooling system makes the LaCie 2big Quadra perfect for even the most noise-sensitive creative environments.
Perfect for Professional Environments
The LaCie 2big Quadra was painstakingly designed to integrate seamlessly into professional environments. With its space-saving design, you can stand it alone vertically and reduce its footprint on your desktop. Even neatly stack it with the LaCie d2 Desk Rack or standard 19" Rackmount Kit. Busy professionals can also set up email alerts, so they can monitor their device before potential problems escalate. They'll know, for example, that the ambient temperature in the room is too high before it causes problems. Even changing the RAID mode is convenient thanks to two-step Easy RAID configuration. It also features an Eco mode that puts the hard disks to sleep after a period of inactivity. This prevents overheating and controls power usage. Whatever the professional environment, the LaCie 2big Quadra delivers convenience and piece of mind.
