Promise Technology Pegasus R6 18TB Direct Attached Storage RAID Array, SATA III 7200 RPM, 800 MBps Sustained Data Transfer Rate

The Promise Technology Pegasus R6 18 TB Direct Attached Storage RAID Array is a Thunderbolt-enabled extra storage system for Mac that gives you room and flexibility for your storage needs. The array features six 3.5" bays, each with a 3 TB 7200 rpm SATA drive, running on a 6 Gbps interface. It also features an advanced RAID engine capable of RAID 0, 1, 5, 6 and 10. The bays are hot swappable, so you can remove drives without unplugging the machine.

Additionally, the DAS RAID array use two channels of bi-directional 10 Gbits/s through the two Thunderbolt ports to move and transfer data. Combined with the RAID options, this feature makes the unit ideal for users who manage and curate video data and graphic artists using high-resolution graphics programs. It can handle multiple streams of uncompressed 10-bit and 12-bit video and up to eight simultaneous uncompressed 720p streams.

You can also use the two Thunderbolt ports to daisy-chain the server in a larger array, conceivably adding up to six units for a total of 36 HDDs, or over 108 TB of storage. Since there are two ports, this unit does not have to reside at the end of the chain and it allows you to add display monitors or other Thunderbolt-enabled devices. The Pegasus comes pre-configured out of the box for Mac computers and is compatible with Time Machine backup software. It also includes Pegasus management software. A Thunderbolt cable is available separately.
