Drobo is a 4-Bay drive enclosure which can take up to 4x 3.5″ SATA hard drives. Please note this is the enclosure only, drives sold separately. You can use your existing drives, mixing brand and capacities or purchase new drives.

Unlike other RAID systems which use traditional RAID 0, RAID 1 and RAID 5 levels, Drobo uses it’s own propriety ‘BeyondRAID‘ system which has the following features:

  • Thin Provisioning
  • Instant Expansion
  • Mixed Drive Size Utilization
  • Automatic Protection Levels
  • Single – or Dual-Disk Redundancy
  • Virtual Hot Spare
  • Data Aware
  • Drive Re-ordering


Further info on ‘BeyondRAID’

Inside every Drobo is 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.

Built on Drobo’s BeyondRAID technology, the Drobo protects your data without any intervention – even in the event of multiple drive failures. You can even switch from single to dual disk redundancy with a single click, ensuring enterprise-level dual parity data protection when required. Drobo’s with BeyondRAID are also self-healing and have virtual hot-spares. If a drive happens to fail, Drobo will automatically re-layout the data to return to a protected state without disruption.

Drobo takes the up front guess work out of determining the amount of capacity you require. Buy the capacity you need today, and when you need more storage, simply replace your smallest drive with a larger one and immediately use that capacity in seconds. You can even mix and match drive brands, capacities and speeds.

To further enhance your experience, every Drobo comes with Smart Volume technology. Smart Volumes are thinly provisioned volumes that automatically utilize capacity as needed from a common pool of storage. Additionally, as data is deleted, free capacity is returned to that common pool, immediately increasing the available capacity.

BeyondRAID along with Smart Volumes deliver next-generation storage technology by bringing together enhanced data protection, reliability, expandability, and ease-of-use.
