With the redesigned 2big, instead of aiming for incremental, LaCie shot for revolutionary. Its all-new industrial design demolishes the status quo and sets a new standard for versatility and reliability. The LaCie 2big also features unbeatable Thunderbolt 2 technology and hardware RAID for sensational performance.

LaCie 9000473U Includes:

  • LaCie 2big
  • External power supply
  • USB 3.0 cable (USB 2.0 compatible)
  • Thunderbolt cable
  • Removable access panel
  • RAID selection tool
  • CD with User Manual and software
  • Quick Install Guide
  • Software:
    • Intego® Backup Manager Pro for Mac®
    • Genie® Backup Manager Pro for PC
    • LaCie Private-Public (protect data with AES 256-bit encryption)
    • LaCie Desktop Manager (provides system monitoring and email alerts for temperature or RAID events)

LaCie 9000473U Features:

  • Thunderbolt 2 Speeds for the 4K Era: With Thunderbolt 2 technology, the interface is no longer the performance bottleneck. For the 2big, LaCie harnessed the breakthrough performance potential of the Thunderbolt 2 I/O, squeezing the absolute best speeds out of the hard disks. Add a hardware RAID controller and 7200RPM disks and the result is incredible, sustained speeds of up to 420MB/s that turbocharge file transfers and backups.
    With this kind of speed, videographers can edit multiple 2K uncompressed 10-bit streams or play back compressed 4K video. Digital photographers can browse a massive RAW photo library with zero lag. And, thanks to support for DisplayPort 1.2, it’s now possible to daisy chain higher-resolution displays such as 4K monitors.
  • Versatility for Pro Environments: With USB 3.0 and Thunderbolt 2 interfaces, the LaCie 2big gets the best possible speeds on any late-model PC or Mac. And, USB 3.0 backward compatibility means that you can connect the LaCie 2big to any standard computer. With support for exFAT and built-in hardware RAID, you can seamlessly connect to both PC and Mac computers without losing your RAID configuration. Whatever your workstation, move mountains of data – fast.
    Thunderbolt 2 continues to support daisy chaining of up to six devices to a computer via a single cable (included in the box). This means that professionals can daisy chain up to five LaCie 2bigs plus a 4K display to a computer, bringing capacity, incredible speed, and convenience. Thunderbolt 2 is also backward compatible and uses the same cables and connectors as first-generation Thunderbolt** devices and computers.
  • RAID for Speed or Security: In addition to compatibility with any computer, hardware RAID delivers sustained performance and better reliability. The LaCie 2big’s range of RAID modes also gives you the flexibility to tailor the product to meet your needs. It’s incredibly easy to change the RAID mode, but impossible to do so accidently. You can leave it in RAID 0*** (FAST) mode to maximize speed and capacity for working on current projects, and then move completed projects to archival storage incredibly quickly.
    Or configure the LaCie 2big in RAID 1 or Mirroring (SAFE) mode, which provides data protection if one disk fails. And thanks to hot-swappable disks, you can simply replace a disk – from the front – with zero data loss and no work interruption. Even in RAID 1, impressive transfer speeds slash the time it takes to perform backups, making it easier to back up more frequently. The LaCie 2big even features JBOD, so you can see and use each disk independently.
  • Innovative Design, Breakthrough Usability: When reengineering the industrial design of the 2big from the ground up, LaCie relentlessly focused on usability for professionals.
  • Power-Saving Mode: Save energy by pressing the power button to spin down disks without interrupting daisy chain transfers. Press and hold the button to shut down the product completely.
  • Packed with Value for Pros: With a bundled professional backup software suite and compatibility with Time Machine™ and Windows Backup, the LaCie 2big includes everything you need for secure backup. And with email alerts, busy professionals can monitor their storage before potential problems escalate. This product also includes LaCie Private-Public software, which lets you prevent unauthorized access by password-protecting volumes with AES 256-bit encryption.
