DriveStation Quad features four high performance NAS hard drives optimized for continuous 24/7/365 operation with enhanced RAID performance. These cost-effective hard drives run cooler, last longer and reduce meantime between failure.



With terabytes of storage, DriveStation Quad provides a reliable, easy to use storage solution to quickly expand the capacity of your PC and Mac computers with universal USB 3.0 plug-and-play.


DriveStation Quad is perfect for backing up your important files. Disaster and hard drive failures can occur unexpectedly; don't leave your important files and treasured memories in the hands of chance. DriveStation Quad features eleven licenses of NovaBACKUP Buffalo Edition for Windows® PCs and servers (one server and ten workstations) and Time Machine support for backing up Mac computers.


DriveStation Quad provides users the flexibility to easily maximize capacity or protect their data using RAID redundancy.

  • RAID 0 combines all drives into a single array offering maximum storage capacity with no redundancy
  • RAID 1 mirrors the four drives, creating an exact copy of data on each drive for fault tolerance
  • RAID 5 stripes the data across all four drives, interspersing parity data to provide an efficient blend of fault tolerance and storage capacity
  • RAID 10 mirrors two sets of hard drives and combines them into a single array, striping data across all mirrored sets for fault tolerance and increased performance



DriveStation Quad's hot swap feature allows a user to replace a hard drive in the event of failure without powering down the device.  Simply remove the defective drive, insert the new drive and the data rebuilds while still being available to clients on the network with zero downtime.



Buffalo Tools is a feature-rich suite of software included with Buffalo DriveStation Quad. Any or all of the following components of Buffalo Tools may be installed on Windows PCs.

  • Buffalo's Backup Utility is a featured backup software for Windows PCs and can be used to back up one or multiple computers with a single Buffalo external hard drive.
  • eco Manager is an energy efficiency tool used to conserve energy and reduce battery consumption by regulating the power usage of the hard drive, cutting power to the drive during extended periods of inactivity.
  • TurboPC includes two components to enhance file transfer performance with external hard drives. It also includes TurboCopy which provides additional system adjustments to increase performance substantially.
