Designed for media creators and data storage professionals who are looking for fast, expandable, and flexible data storage and protection for large media collections and performance demanding applications, as well as photo and video editing, the 5Dt 5-Bay Thunderbolt 2 Enclosure from Drobo is equipped with five 3.5" SATA drive bays that support SATA III 6 Gb/s and SATA II 3 Gb/s drives. Also known as the 5D Turbo Edition, this device distinguishes itself from the original Drobo 5D through the inclusion of Thunderbolt 2 technology, which is accessed through two integrated Thunderbolt 2 ports, which operate with bi-directional data transfer speeds of up to 20 Gb/s. While one of the Thunderbolt 2 ports is used to connect the 5Dt to your compatible Windows or Mac system, the second one is used to daisy-chain up to six Thunderbolt devices together, including one 4K display. There is also one USB 3.0 port, which transfers data at speeds up to 5 Gb/s.
To help complement the speeds of Thunderbolt 2, the 5Dt has been built with Drobo's Accelerator Bay, which uses an included mSATA SSD to boost system performance. It accomplishes this by placing data that is read or written into SSD storage. When the data is active, it is stored in the SSD, and will be moved back to the hard drive tier as its use decreases.
To facilitate data protection, Drobo's BeyondRAID technology enables single or dual-drive redundancy. If there are any empty drive bays, BeyondRAID allows additional drives to be inserted into the array, where they would be automatically configured. If all drive bays are occupied, simply replace the smallest capacity drive with a larger one and BeyondRAID will handle the rest. BeyondRAID is also what allows drives of varying capacities to work in the same unit, which helps enable future expansion as larger drives become available.
Additional data protection is provided by the included rechargeable battery, which helps protect data stored in the 5Dt's cache. If there were to be a sudden power loss, the battery allows the Drobo to stay powered long enough for the cached data to be written to non-volatile storage. Cooling is provided by a variable-speed fan and once installed, the hard drives can be configured to spin down when they're not in use, helping to further reduce noise and energy. Also, the LEDs can be dimmed to reduce light pollution when working in sensitive environments. The Drobo 5Dt also includes a 3.3' Thunderbolt 2 cable, a 5.9' USB 3.0 cable, a 100-240 VAC power supply that runs at 50-60 Hz, and a 5.9' power cord. Protection is provided by a limited 3-year DroboCare warranty, which may be renewed up to two times using Drobo's 1-year warranty renewal, for a total of five years of coverage.
