Part # roben-3ts

ROBEN-3TS incorporates the best technology from our mission critical defense and aerospace systems. ROBEN-3TS features three (3) full-length, full-height PCIe slots with a robust, high speed backplane.

The rack-mountable aluminum chassis was designed for integrated removable storage expansion, with eight (8) 2.5-inch SATA/SAS HDD or SSD hard drive bays, a fanless 520-watt power supply, auxiliary power, and features two (2) 40mm 6.37 CFM Drive Bay Fans.

This added power can be channeled through lightning fast Thunderbolt 2 technology at 20Gbps. With 3-Slot PCIe and internal storage expansion, ROBEN-3TS empowers the serious audio, video, and design professional to transform their computer into a powerful workstation – a sidekick for the creative hero.

With the ROBEN-3TS, you will have the option of using the system in a desktop or rack-mounted configuration, adding higher versatility to your workflow. Also, by simply connecting two or more ROBEN-3TS systems in a series, you can create the performance equivalent of a server, without the cost and complexity.

ROBEN-3TS Frequently Asked Questions

Is a Thunderbolt cable included?

The Thunderbolt cable is sold separately.

Do I need any special Firmware, Software, or Driver?

No firmware, software or driver is required from Magma, but you may need an updated driver for your PCIe card.

What types of PCIe cards can be used with the ROBEN-3TS?

Check the Thunderbolt PCIe Card Compatibility for a list of cards that have Thunderbolt 2 Compatible drivers. If your PCIe card is not on this list, contact the card manufacturer to ask if they have a Thunderbolt 2 Compatible driver.

Can the Magma Thunderbolt 2 Interface add-in card be used in a Mac Tower?

No, it will not work as an add-in PCIe card in a Mac Tower.

Do older Thunderbolt devices on a Thunderbolt 2 daisy chain affect performance?

Yes. If you have a mix of generations on a Thunderbolt 2 daisy chain, make sure that the Thunderbolt devices sit after the Thunderbolt 2 devices on the chain. Anything placed after a first generation Thunderbolt device will operate at Thunderbolt speeds.

What controller cards are recommended for use when adding hard drives to the ROBEN-3TS?

Magma recommends using either an ATTO ESAS H608 or an ATTO ESAS R608 HBA drive controller card with ROBEN-3TS. Please see our Thunderbolt PCIe Card Compatibility for more Thunderbolt controller card options.
