Any Place. Any User. Single Interface.

Introducing the True Hybrid Cloud
With the LaCie 5big NAS running NAS OS 3, you get a true hybrid cloud: integrated network-attached and secure cloud storage. LaCie is alone in the market having its own cloud storage product, Wuala. As a result, LaCie is uniquely positioned to deliver a seamless hybrid cloud solution.
Easy Setup,
Seamless Integration

Simply connect the product and install the Wuala client, and instantly you have 100GB of free trial Wuala Business cloud storage**. Wuala file system integration means both network and cloud storage mounts on your computer just like an external hard drive. So you can easily drag and drop files onto the LaCie 5big or the cloud. It also lets you access and work on files wherever you go – and even edit files with productivity software – without needing to download them.

Complete Compatibility
Not only does Wuala work on Windows®, Mac®, and Linux, but also on mobile devices (iOS™ and Android™). Just install the Wuala app on your smart phone or tablet to gain access to any file stored on your LaCie 5big. Make your data as mobile as your employees are (but constantly available).

Fast Professional Collaboration

Faster Internal File Sharing
Boost your business productivity with read speeds up to 200MB/s in RAID 5***. The LaCie 5big is powered by a dual-core 2.13GHz Intel® 64-bit Atom™ processor and 4GB RAM. It also features dual LAN and link aggregation for optimized network speeds. This combination optimizes file transfers between employees, and even provides enough performance to edit video.
Work Smarter, Work Together
Using Wuala, you can set up automatic files syncs between computers and the NAS or computers and the cloud, ensuring everyone’s looking at the most current version of files. Sync makes sure that an employee in sales, for example, won't use an outdated price list, or be unable to pull up marketing collateral during a sales pitch. Since your Wuala Business users have access to a shared pool of storage, it's easy to keep everyone on the same page.

Better External File Sharing
What's more, instead of using FTP or email to share files with external clients, simply provide them access to LaCie 5big’s browser-based file explorer. They 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.

Formidable Data Security. Simplified.

Professional Security, Suitable for Novices
The LaCie 5big goes the extra mile to protect your data. In addition to industry-standard RAID modes, the 5big is the first LaCie product to ship with SimplyRAID, which makes RAID management easy enough for any novice. Either manually select a RAID mode such as 5, 1▴, or 0, or activate SimplyRAID. It ensures that even if you're not an expert, you still benefit from the best data security. Sophisticated protection. Simple usage.
RAID for Bulletproof
Hardware Security

With SimplyRAID, you also get the perfect compromise between speed and disk-failure proof, hardware-level data protection. If a 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 as your business grows. Automatic RAID expansion means that it's easy to add additional or higher capacity disks without losing your data. Using SimplyRAID, you also get improved available storage compared to traditional RAID solutions when using disks of different sizes. These features let you reduce your initial investment while ensuring a long-term solution.
Industry-Best Cloud Security
Files stored on the cloud are encrypted even before they leave your computer. So no one, not even a LaCie employee, could ever access them. On the other hand, competing cloud storage services could read your files due to employee wrongdoing or court order. Wuala also employs bank-level security to protect files stored on its servers.

Complete Backup Solution

Everything you Need, in the Box
The LaCie 5big 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.
Offsite Backup for Ultra Security
You can even add offsite backup to your data protection strategy. Wuala lets you create backup jobs that back up a computer's folder onto the cloud. An employee accidentally deletes an important file or his hard drive fails? Regardless of your backup method – 3rd party software or Wuala – restore lost files in seconds and get employees back on track.

Automated NAS Backup
The LaCie 5big also takes the hassle and potential for human error out of backing itself up. You can replicate your LaCie 5big's storage onto an attached USB 3.0/2.0 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

Rescue Utility
The 5big is the first product to feature LaCie's Rescue utility. This browser-based tool gives administrators a DVD-free way to reinstall or repair the NAS OS, and to recover from system failure. Using the included USB key, the browser-based LaCie Rescue allows you to install the OS on a diskless chassis. As a result, it's easy to replace all your NAS' disks at the same time, or set up a LaCie 5big that shipped without disks. In case of system failure, LaCie Rescue launches automatically to help you recover files from a damaged system via FTP, repair the OS, or completely restore the NAS to factory settings.
Easy Maintenance and Troubleshooting
Prevent downtime by keeping a close eye on your hardware. The LaCie 5big 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.
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. Host multiple virtual machines using several iSCSI targets, and even benefit from iSCSI MPIO (multi-path I/O) in cluster configuration.

Enhanced Network Management
The LaCie 5big lets you specify which services are active on which of the Ethernet interfaces. For example, use one LAN for iSCSI and the other for AFP/SMB sharing. Dual LAN lets users aggregate ports for superior performance (bonding) or fault tolerance (failover). It even lets you create multiple volumes from NAS storage, so you can allocate different volumes for different purposes.
Dual Cooling for Long-Term Reliability
The cooling system can have a dramatic impact on the long-term reliability of your server. The LaCie 5big's dual cooling is the best protection against overheating throughout its lifespan. First, its solid aluminum casing diverts and dissipates heat effectively. Second, its whisper-quiet, thermo-regulated Noctua® fan automatically adapts its spinning speed to the internal temperature. As a result, the fan cools the components, which is vital for a better long-term investment.
