Fast Professional Collaboration

Faster Internal File Sharing
Boost your b usiness productivity with up to 100 MB/s* transfer speeds. The LaCie 2big is powered by a 2 GHz processor and a highly efficient file system. This combination optimizes file transfers between employees while ensuring full performance even with simultaneous transfers.
Your Own Private Cloud
Using Sdrive for PC, Mac®, or mobile devices, your entire team can access files stored on the LaCie 2big wherever they are in the world. Thanks to file system integration, the LaCie 2big’s storage mounts on your computer just like an external hard drive, so you can easily drag and drop files from your computer onto the LaCie 2big.

Better External File Sharing
What's more, instead of using FTP or email to share files with external clients, simply provide them with access to LaCie 2big’s browser-based file explorer. Clients can download files directly without needing to be granted access to your company's network. No file size restrictions means you can share large files easier than ever.

Easy Setup, Seamless Integration

More Features. Fewer Headaches.
Just plug the LaCie 2big into your network to begin centralizing your files and backups. Effortlessly configure and set up multiple devices with the clean, intuitive LaCie NAS OS 3 interface. From the convenience of a browser, NAS OS 3 incorporates the NAS software features you need to share files and protect your business’ data.

Complete Compatibility
Dramatically simplify how you manage users and groups with Active Directory® support. It only takes 30 seconds to join the LaCie 2big to an existing domain, and then users, groups, and permissions can be quickly imported and synced from your existing infrastructure. Once the initial set up is complete, you will never need to do it again. Zero repetitive tasks.

Formidable Data Security. Simplified.

(RAID 0)

(RAID 1)

RAID for Bulletproof
Hardware Security

The LaCie 2big features RAID 1, which provides disk-failure proof, hardware-level data protection. If a single disk fails, you can replace it without turning off your appliance. Just swap in a new one without losing a single byte of data. Whatever the challenge, zero data loss, zero work interruption.

Minimal Investment,
Maximum Scalability

Opt for the diskless model** and simply add more storage capacity as your business grows. Automatic RAID expansion means that it's easy to add higher capacity disks without losing your data. These features let you reduce your initial investment while ensuring a long-term solution.

Complete Backup Solution

Everything You Need, in the Box
The LaCie 2big comes with everything you need to back up your office's computers. It includes three client licenses for Genie® Backup Manager Pro™ for Windows and three licenses for Intego® Backup Manager Pro™ for Mac (additional licenses can be purchased online). Install the included software on computers to be backed up, or simply use Time Machine® or Windows Backup.

Automated NAS Backup
The LaCie 2big NAS also takes the hassle and potential for human error out of backing itself up. You can replicate your LaCie 2big's storage onto an attached USB/eSATA hard drive, or vice-versa. Create automatic backup jobs tailored to each of your attached devices. You can also use your NAS to back up another NAS, whether it's on the local network or remote***. Even configure a nightly backup of your NAS onto a backup server in a completely different building.

Advanced Features for Small Business

Dual Cooling for Long-Term Reliability
The LaCie 2big's advanced dual cooling system ensures long-term reliability by preventing overheating. Its solid-aluminum casing provides 60% more surface area, which diverts and dissipates heat more efficiently. In addition, its thermoregulated fan turns on and off according to internal temperature. It cools the components while reducing electricity usage.
Energy-Saving Innovations
The LaCie 2big helps you to reduce power consumption by letting you control its energy usage. In Eco Mode, it uses one-tenth of the energy of the previous generation of LaCie NAS without reducing employee access to data. You can also schedule shut down and restart depending on the day of the week.

Get Ready for Virtualization
Support for multiple iSCSI initiators and targets brings dramatic flexibility to your virtualization scheme, including those that integrate Citrix®, VMware® or Hyper-V® servers. Combine your storage into data center arrays while letting host computers mount network storage as if it were direct-attached disks. Even host multiple virtual machines using several iSCSI targets.
Easy Maintenance and Troubleshooting
Prevent downtime by keeping a close eye on your hardware. The LaCie 2big now features hardware monitoring that alerts you in real-time of potential issues with the fan, CPU, and RAM. It also features SMART hard disk diagnostics. Stay on top of your data security with hardware status email alerts.
