Promise Pegasus series RAID enclosures  (Source: Promise)
First hardware RAID enclosures for Thunderbolt

When Apple adopts a new bus interface, you can bet that there will be companies waiting in a line to support the standard with new peripherals for users. The new MacBook Pros debuted yesterday and along with the new machines came a new I/O interface called Thunderbolt.

Promise has announced that it has the first new hardware RAID solution for the Thunderbolt interface with its new line of gear in the Pegasus series. The Promise line was designed to provide users with raw speed and is optimized for media and entertainment users. The Pegasus gear will come in 4-bay and 6-bay enclosures and will support up to 12TB of storage.

“Intel is excited about the superior performance and simplicity Thunderbolt technology and PROMISE’s Pegasus family of products will bring to consumers and media professionals trying to keep up with the explosion of digital media,” said Jason Ziller, Director, Thunderbolt Planning and Marketing, Intel Corporation.

The Thunderbolt interface supports speeds of 800MB/s sustained, which is 12x faster than FireWire 800 and 20x faster than USB 2.0 ports. The RAID solutions are aimed at professionals that need to store and edit video and play multiple streams of uncompressed 8 and 10-bit HD video on the new MacBook Pro notebooks. The storage solutions are compatible with Time Machine as well.

“PROMISE is thrilled to deliver one of the first peripherals to feature the blazing speed of Thunderbolt technology,” said James Lee, CEO, PROMISE Technology. “Pegasus brings groundbreaking RAID performance to creative professionals in the studio, on location and in the home. Pegasus is the ultimate complement to PROMISE’s extensive storage offerings ranging from the Apple qualified VTrak subsystems to DS4600 – Direct Attached Storage for home, SOHO and AV professionals.”

Multiple Pegasus enclosures can be connected to one another to extend storage capacity up to 72TB or a display can be connected to the storage device as well. RAID modes supported include RAID 0, 1, 5, 6, 10, 50 and 60. Each Pegasus device has two Thunderbolt ports onboard. Pricing is unannounced at this time, but the solutions will land in Q2.

LaCie unveiled a smaller storage solution yesterday with a Little Big Disk version with Thunderbolt support.

Actually it is you who is wrong. Think about what you just said. Yes every 8 bits makes a byte. So what's your point? How is a sustained rate of 800MB/s wrong?

Let me do some quick math for you. The current iteration of Thunderbolt/Light Peak has a theoretical maximum of 10Gb/s bi-directional. That is 1.25GB/s. That is 1280MB/s. Now we all know you never get the theoritical maximum with any bus, so 800MB/s seems to be the number Intel has found that is sustainable and expected.

Your post is trying to imply the the author should have either posted 100MB/s or 800Mb/s... can I simply ask, are you ignorant of what Light Peak is? You currently can get 100MB/s sustained out of most of WD/Seagate HDDs on a SATA I (1.5Gbps) bus.

The journalist got it right and you are wrong.

My bad, you're correct.
