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.

I'm not entirely sure why you brought up SSDs to counter the practicality of Thunderbolt with a RAID setup. You know what RAID is right? Array of multiple disks for either redundancy or performance in striping?

The reason why the huge bandwidth of Thunderbolt is useful is for a multiple disk setup such as, drum roll, a RAID array. An external RAID array, one that is probably more affordable than what is out there without looking at the SAN offerings of OEMS with Windows Home Server. And even then you're limited to Gbit Ethernet at best.

There are probably lots of home users who have large stores of media that they would prefer never too lose considering a hard drive can die anytime. And yes, a hard drive, because when it comes to mass storage, you don't need the performance of a SSD.
