Sdrive for
Anywhere Access


Using Sdrive™ apps for PC, Mac®, or mobile devices, your entire team can access files stored on your LaCie NAS, wherever they are in the world. Thanks to file system integration, the storage of your LaCie NAS mounts on your computer just like an external hard drive so you can easily drag and drop files from your computer onto the LaCie NAS.

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 NAS’s browser-based file explorer. They can download files directly without needing to be granted access to your company's network. Having no file size restrictions means that you can share large files easier than ever.

All-Points Security for Constant Data Availability

Files need to be constantly available or productivity suffers. That's why LaCie designed NAS OS 3 to protect files stored on the NAS with disk-failure proof, hardware-level RAID protection. If a single disk fails, you can replace it without turning off your device. Just swap in a new one without losing a single byte of data. The SimplyRAID feature** can even control RAID for you, making advanced data security simple enough for novices. Using SimplyRAID, you also get improved available storage compared to traditional RAID solutions when using disks of different sizes.
