Buffalo HD-DN040T/R6 overview

  • 1Description

The Buffalo DriveStation Ultra 40TB (10 x 4TB) 10-Bay Thunderbolt 2 RAID Array comes with ten 4TB NAS hard drives along with two Thunderbolt 2 connectors so you can quickly retrieve data with your computer system. These drives can be hardware configured in RAID modes 0, 5, or 6. Buffalo has preconfigured the DriveStation Ultra in RAID 6. When connected via Thunderbolt and set in RAID 0, the DriveStation Ultra can deliver write speeds of up to 1243 MB/s. In addition to Thunderbolt, it has an eSATA port and USB port to provide data storage for a Mac and PC. For file sharing, it can access a network via a built-in 10/100 jack.

Thunderbolt 2 Speeds
The DriveStation Ultra comes equipped with two Thunderbolt 2 connectors, allowing Mac users to experience write speeds up to 1243 MB/s using RAID 0. This connection is suitable for transferring and storing large files such as high-resolution videos.
High Capacity
With a capacity of 40TB, you can store high-resolution videos and other large files on the DriveStation Ultra. The two Thunderbolt 2 ports provide the ability to daisy chain up to 6 DriveStation Ultras, and with 6 ports on a single Mac Pro you can achieve greater amounts of storage.
Multi-Interface Support
In addition to the ultra-fast Thunderbolt 2 connection for Mac, you can connect to the DriveStation Ultra with USB 3.0 and eSATA connections, allowing the desktop hard drive to be accessible for both Mac and PC users.
Desktop Form Factor
The DriveStation Ultra comes as a desktop solution, conveniently providing up to 40TB of data within reach.
Performance Hard Drives
The DriveStation Ultra features ten NAS hard drives, which are optimized for continuous 24/7/365 operation that run cooler and save power.
Safe Data Storage
The DriveStation Ultra 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 5 stripes the data across all 10 drives, interspersing parity data to provide an efficient blend of fault tolerance and storage capacity
  • RAID 6 uses two parity stripes per hard drive, allowing two hard drives to fail without any data loss
