The Faster, Easier Drobo for Your Network
The Drobo 5N was designed with one purpose in mind: to deliver the best ever experience sharing storage and accessing data. From the moment you plug it in and it is instantly accessible on your network, you'll know there's nothing like it. The Drobo 5N is perfect for any connected home, home office, or small office environment needing a simple, safe device for sharing and backing up data over the network.
Not only is Drobo 5N fast, but it's easy-to-use, expandable, flexible, and protected—exactly what's expected from a Drobo. You can safely store and edit photos, videos, and audio files as well as store and back up all the computers on your network.
Data Protection and Expandability Made Simple
Built on award-winning BeyondRAID technology with single- or dual-drive redundancy, Drobo 5N protects your data without any user interaction, even in the event of multiple drive failures.
Drives can be added or hot-swapped on-the-fly for storage expansion with zero downtime. If you're running low on space, the lights on the front tell you what to do. Just add a drive in an empty bay or remove a smaller drive and replace it with a larger one.
The Drobo 5N is equipped with a single Gigabit Ethernet port for network connectivity and connects directly to your network to make sharing your data easy. Just plug it into any switch or wireless router and you're ready to go. You can even connect the Drobo 5N directly to the Ethernet port on your computer without having to configure any settings.
Capacity AND Performance
Data-Aware Tiering technology, usually reserved for business-class storage solutions, is also available in this networked Drobo. It intelligently uses the high-performance SSDs to accelerate performance of the storage array, allowing applications such as Adobe Lightroom and Apple iPhoto or iTunes fast access to data. To keep capacity of the Drobo at a maximum, the Drobo Accelerator Bay accepts an industry-standard mSATA SSD, leaving all five 3.5" drives bays available for high-capacity HDDs.
If getting the fastest performance possible is your thing, you can also load up every drive bay with SSDs. Drobo gives you the flexibility to choose.
Power Protecting Your Critical Data
Drobo doesn't just protect you from a drive failure, but also from potential data loss after a power outage. Often found only in arrays that cost tens of thousands of dollars, Drobo 5N includes a battery that protects all data in memory, or cache, that is, data on its way to the drives.
When power spontaneously goes away, the battery keeps the Drobo alive long enough for the data to be written to non-volatile storage, ensuring your important information is safe. This battery recharges itself and is designed to last for the life of the product.
Designed for You
Drobo devices have always been space efficient and the Drobo 5N is no exception. It was designed from the ground up to provide very high capacity without taking up a lot of your valuable desk space. It is compact because of Drobo's unique carrierless drive-bay design, allowing drives to be installed very close to each other.
Drobo 5N is also significantly quieter than previous-generation Drobos due to its tuned, large, variable-speed cooling fan. You can even configure Drobo to spin down drives when they're not in use to further reduce noise and save energy.
