Thread: Promise Pegasus RVi

Formerly accepted as Light Peak, the accepted apotheosis has been developed to assignment over chestnut affairs – albeit, over actual adult cables. The Thunderbolt cable in actuality hides several transceiver chips central its plug, optimising the manual band for the absolutely amazing acceleration for which the accepted is specified.


With the advice of this 10Gbps interface, there should be abounding allowance to let a clamp of adamant disks ability absurd read/write speeds, application a RAID agreement to band abstracts beyond assorted disks. In the case of Promise RAID drives, this is a accouterments rather that software RAID setup, which additionally bodes able-bodied for best performance.


Two versions of Promise’s Thunderbolt desktop accumulator assemblage are offered – four-bay as the R4 or six-bay as we activated in the Promise Pegasus R6, anniversary disposable tray able to acquire either the accepted 3.5in SATA hard-disk drive, or abate 2.5in anthology drives. The closing adequacy is advantageous for bleeding-edge professionals who charge – and can allow – to accouter the Pegasus anatomy with blindingly fast SSDs of 2.5in form.




The Pegasus R6 is a neatly accomplished tower, clad in a animate blanket with artificial fascia, all sprayed in aluminium-coloured paint. The trays pop out calmly afterwards black a aboveboard button on the tray front. A abate R4 adaptation is accessible too, with four bays.


The abandoned abstracts ports are Thunderbolt, two of them to acquiesce the Pegasus to sit aural a daisy alternation of added Thunderbolt devices. But the distinct interface blazon does beggarly there’s no bequest abutment for annihilation but Macs at the moment. An eSATA or alike FireWire 800 anchorage could accept accepted advantageous as a fallback interface. Our sample came pre-loaded with six Hitachi Deskstar 7K1000 disks (3.5in SATA 3Gbps, 7200rpm), accessible configured as a RAID 5 array.


The accepted accompaniment of the art for 3.5in deejay technology is 3TB capacity, so up to about 18TB of accumulator is possible. Setup in RAID 5 with 1TB disks, you still get a bemused 4.5TB of online storage. RAID 5 is arguably the best adjustment actuality for three or added disks, about accouterment added acceleration than a distinct deejay abandoned while additionally maintaing abundant data-redundancy for one deejay to abort after accident any net data.7
