Promise Pegasus R4 8TB RAID Storage Array With Thunderbolt - H5185VCA

Promise Pegasus R4 is the first four-bay high-performance hardware RAID solutions designed to unleash the raw power of Thunderbolt. Pegasus R4 features four 1 TB 7200-rpm hard drives in a compact hardware RAID enclosure with Thunderbolt connectivity. Delivering over 500 Mbps of disk performance, Pegasus is compatible with Mac systems with Thunderbolt and required Thunderbolt cable. Thunderbolt technology is a high-speed, dual-protocol I/O technology designed for performance, simplicity, and flexibility. Capable of delivering a blistering two channels of bi-directional 10 Gbps per port of performance, Thunderbolt technology combines PCI Express and Display port into an interface using a single cable for connectivity to devices. Thunderbolt technology was developed by Intel and brought to market with technical collaboration from Apple. Pegasus R4 is ideal for creative pro workstations, small servers, power users, and consumers who desire stylish high-capacity external storage with high performance and enterprise level data protection. Pegasus R4 is capable of delivering over 500 Mbps of bandwidth that is 10 times faster than USB 2.0.


  • Lightning Fast Performance
    With I/O rates of over 800 MB/s, Pegasus delivers a massive and unprecedented leap in performance, allowing amateur professionals, audio engineers, photographers, and post production engineers, to unleash the raw power of Pegasus, enabled with Thunderbolt Technology. Final Cut professionals can ingest, edit, and playback, multiple streams of uncompressed HD (8-bit and 10-bit) video, while protecting valuable workflows, audio sessions, and other creative media content, with PROMISE's award winning, enterprise level, RAID6 engine (features mature error handling schemes for the ultimate in data protection). Graphic artists utilizing Photoshop and Maya 3D animation can both manipulate and archive high resolution graphics on Pegasus, with relative ease and lightning fast responsiveness.
  • Flexible Connectivity
    The multi-protocol support of Thunderbolt Technology enables Pegasus to deliver amazing flexibility. Daisy-chain more than one Pegasus enclosures to a single Thunderbolt technology port or connect a display to Pegasus for the ultimate in convenience and interface connectivity.
  • Fast, Safe and Reliable
    Digital Media consumption is growing at an astonishing rate, and is part of everyone's life. Featuring, two, high performance, 10Gb/s bi-directional channels, and PROMISE enterprise-level RAID 6 protection, Pegasus provides fast, safe, and reliable external storage, essential for protecting your music, photos, videos, and other valuable data. Pegasus provides massive storage, and fast performance for popular applications, including Final Cut Pro, Garageband, iTunes, iPhoto, and Photoshop. Pegasus can be used, in conjunction with Apple's Time Machine utility (in Mac OS X), to store backups of invaluable digital media, documents, or an entire computer (or workstation).
  • Easy to Use
    Pegasus comes pre-configured out of the box. Simply unpack, supply power, and connect the Thunderbolt cable (currently, only available from Apple) to the Thunderbolt port on your computer, and you will be ready to either ingest/edit production video, or store all your important documents, music, photos, and videos. Management of Pegasus is made possible through an easy to use, all new, made-for-Mac OS X GUI utility.
  • One More Thing, Eco-Friendly.
    Pegasus is RoHS compliant; in simple terms Pegasus is eco-friendly, keeping harmful lead out of the environment and our delicate ecosystems. Consuming a mere 78 watts under full load with six hard drives installed, Pegasus uses roughly 26% of the power consumed by the average 300 watt power supply in standard computers. Sporting a new enclosure design, an 80Plus power supply and a smart cooling fan, system noise is never an issue making Pegasus ideal for desktop, small office environments and or any room in the home.

    Comments about Promise Pegasus R4 8TB RAID Storage Array With Thunderbolt:

    I love how fast it is and quiet. It works very nicely! The only complain I have: the description states it is 8TB (4drives 2TB each), but actually one of the drives is already sacrificed for the RAID management which takes about 2TB, so you only have 6TB left to work with. I was dissapointed about this mis-understanding. They said you can erase the Raid system and get all 8TB available, but hey, that's why we pay such high price in the first place: to get it all secured with this RAID system - so of course you keep it there. That way, even if your 1 drive goes bad - you don't really lose any data... Overall, I am currently still very happy with how it performs.
