Formerly known as Light Peak, this hyperfast I/O system is said to provide two channels of 10Gbps transfers. This contrasts with the emerging USB 3.0 standard, specified to 4.8Gbps.
On its exhibition stand at CeBIT 2011, Promise Technology demonstrated some of the capability of the system by playing four streams of uncompressed high-definition video.
For the Pegasus R6, Promise Technology cites over 800MBps raw performance. And in the demonstration visitors could see the setup taking the four-feed 1920-by-1080, 10-bit uncompressed datastream in its stride.
Played from a new MacBook Pro, Mac OS X’s Activity Monitor app showed a stream that averaged 630MBps, with a 650.9MBps peak datarate.
Unlike some RAID systems, Promise uses a hardware RAID system, rather than conducted through software by a unit’s CPU.
Worldwide pricing for the Promise Pegasus is to be announced, with availability said to be within the second quarter of this year.
