No Headache Data Redundancy
Drobo utilizes the revolutionary BeyondRAID storage technology that protects data against a hard disk crash, yet is simple enough for anyone to use. As long as you have more than a single disk in Drobo, all data on Drobo is safe no matter which hard disk fails. There’s no need to worry about anything else.
Incomparable Expandability
Your library of data grows every moment. Now, your storage solution expands in seconds, too. Drobo holds up to four hard drives, can expand at any time and supports up to 16TB on a single volume as disk sizes increase. Choose how big you want your Drobo today with any combination of drives capacities.
Windows, Mac, Linux
Drobo works with all three major operating system platforms and their native file systems.
Hard Drives a la carte
Unlike other storage solutions, Drobo allows you to purchase as much or as little storage as you like up front. Since you can expand at any time, Drobo is the right solution for your budget.

Consolidate Your Storage
Avoid the danger, mess, and hassle of multiple external storage "solutions" and upgrade to Drobo, with the world's only safe, expandable storage technology.
Features
BeyondRAID - Storage without limitations

BeyondRAID leverages the benefits of traditional RAID systems, while leaving many of the limitations behind. This next-generation of redundant storage technology brings together safety, reliability, expandability, efficiency and ease-of-use.
BeyondRAID fits in the same place of the software stack as traditional RAID between the file system and the driver. Hence, BeyondRAID can be adopted without any change in infrastructure, allowing you to maintain your current file system and operating system, while eliminating the friction costs typically associated with moving to a new technology platform.
BeyondRAID is RAID without Regrets

Data Robotics BeyondRAID solves these two critical issues, delivering flexibility without downtime. Built on an advanced storage virtualization platform, BeyondRAID chooses the correct RAID algorithm based on data protection needs at any given moment. Since the technology works at the block level, it can write blocks of data that alternate between data protection methodologies. If an IT manager needs to add storage capacity to a Drobo product, he or she can simply insert additional disk drives or replace the smallest disks-no need to change RAID levels, purchase a new storage array or go through the complex administration of pooling RAID groups. The BeyondRAID featured on DroboPro even allows IT managers to switch from single to dual disk redundancy with a single click, thereby ensuring enterprise-level dual parity data protection if required.
Greatest Feature -- Plug it in and automatically upgrade your peace of mind.
Go Faster with FireWire 800. Hi-Speed USB 2.0.
With FireWire 800 alongside USB 2.0 and an upgraded core processor, Drobo is now the fastest product in its class. It is the perfect solution for both primary and backup storage of large media and productivity files such as video, photos, music, audio, and troves of documents and spreadsheets. In fact, even if you're now using USB 2.0, the new Drobo is up to three times as fast its predecessor in typical usage.

Consumer Mindset, Enterprise Feature Set.
Drobo was designed to meet a stringent design requirement: Anyone should be able to use Drobo regardless of technical experience. It is ready to go out of the box and will always stay that way. Drobo does all the work of managing an enterprise-grade your storage system for you.
No Software or Drivers are Needed!
The Drobo magic comes from the software that's built into the hardware called BeyondRAID—an advanced storage technology. Drobo does everything for you from expanding capacity when you add a drive, to self-healing around drive failures and data errors. Drobo also includes a powerful desktop software utility called Drobo Dashboard that shows you what Drobo is up to and adds important functionality including firmware updates, formatting options and email alerts.
Additional Features

Green Means Go. Drobo is equipped with a series of LEDs on its front-side that shows you all you need to know about how Drobo is doing and how much free capacity you have. If you've ever successful navigated a traffic signal, you're a certified Drobo expert. (Check your mailbox. Your certificate is on its way.) Also, Drobo takes bare hard drives with no need for screws and screwdrivers, drive carriers or any other impediments to your storage needs.

Drobo knows where each block of data is stored on each hard drive. This allows Drobo to provide a capacity meter to let you know when it's running out of space and enables it to automatically protect data and recover from drive failures more quickly than traditional RAID.

Unlike rigid, inflexible traditional RAID solutions, Drobo can utilize the capacity of different size hard drives. Using an intelligent mixture of industry-standard practices to protect your data, Drobo offers significantly more storage capacity than standard RAID solutions. It functions just as you would expect storage to work: add drives or replace smaller drives with larger ones, and get more space. No matter what combination of drives you use, Drobo will almost always be more efficient than RAID 5. To find out exactly how much free capacity you'll have with your choice of disk capacities try out our interactive Drobolator.

Hard drives get bigger and cheaper all the time. Save money - don't buy storage capacity until you need it. It's so easy to add drives to Drobo, you can start with the fewest drives or minimum capacity you need today and just add or replace drives to increase capacity later. Now, you can take advantage of regular disk drive capacity improvements and pricing declines.

Add drives to Drobo at any time. Mix 'n match capacities, brands or speeds. No downtime, data migration, or waiting to access new capacity. No need to buy an entirely new system when Drobo is full. As long as disk drive capacities continue to increase beyond the capacities you have purchased, you can upgrade Drobo simply by replacing your smallest drives with larger ones. Today Drobo can grow up to 16TB on a single volume as maximum drive sizes grow up to a theoretical 4TB on a single disk.
