Drobo: The Most Advanced 4-Bay Drobo Ever
This third generation of the Drobo is more affordable than ever and features a completely new architecture making it more than 3x faster than the previous
generation. More impressive, rebuild times are 4x faster delivering maximum data availability in the event of a drive failure. With the inclusion of battery
backup technology, Drobo provides even more data protection in the face of an unplanned power outage.
The latest generation of the Drobo 4-bay holds true to the unique design and simplicity that has made Drobo the best desktop storage solution for storing and
protection all your data. No storage expertise is required to ensure your data is always safe and protected. Best of all your Drobo will be ultra quiet and look
great on your desk.
Data Protection Made Simple
Enhanced Time Machine Support
Drobo is simply the easiest to manage storage
solution available. Like all Drobo products, the
third generation Drobo is built upon the awardwinning BeyondRAID™ technology. BeyondRAID
can be configured to protect against one or two
simultaneous drive failures with just one click,
automatically protecting your data without any
user intervention. In addition, you can purchase
the capacity that you need now and increase
space by adding drives into empty slots, or
by swapping smaller drives with larger ones.
When you do, the additional capacity is instantly
Apple’s Time Machine can consume all of the
capacity of an external storage system without
a simple way to set capacity limits. Utilizing
Drobo Dashboard the new Drobo allows users
to easily allocate a specific amount of capacity
to be dedicated for backups and preserves the
remaining space for data storage.
Investment Protection
Drobo takes upgradability to the next level. Not
only can you upgrade capacity as drives become
more affordable and drive capacities increase
with no downtime by adding or swapping in
larger drives, you can also seamlessly upgrade
to the latest platform Drobo has to offer. The
process of upgrading is as simple as removing
the existing disk pack from your previous
generation system, and moving it to your new
Drobo. Upgrading to the latest and greatest
technology not only gives you an instant
performance boost, but also delivers all the new
features and benefits of your new Drobo.
Drobo Data Sheet | Drobo
Designed for You
Drobo Dashboard
Drobo Dashboard is the single tool used to
centrally manage all of your Drobo devices.
Drobo Dashboard displays status as if all
of your Drobos were right in front of you
with the same status lights and capacity
gauge that are on the front panel. All
administration tasks are a single click away.
Drobo devices have always been space efficient
and this latest Drobo is no exception. It has
been designed to provide high capacity without
taking up a lot of your valuable desk space. It is
compact because of Drobo’s unique carrier-less
drive bay design, allowing drives to be installed
very close to each other.
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. This latest generation of
Drobo includes battery backup technology that
protects all data in memory or cache. When
power spontaneously goes away, Drobo moves
any in-flight data to onboard flash in your
Drobo so it will be protected. The protected
data will be moved to your disk drives once
power is restored. This ensures your important
information is safe and sound. Even better, your
battery recharges itself and is designed to last
for the life of you Drobo.
As Easy as Reading a Traffic Light
Lights on the front tell you what’s happening – if
you can read a traffic light, you’re already a
Drobo expert. Each blue LED along the bottom
represents 10% utilization letting you know
exactly how much capacity is consumed. Green,
yellow or red LEDs keep you informed of each
drives status at all times. Unsure of what the
lights mean? Simply take off the uniquely
designed magnetic cover and all the information
is right there on the back.
