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.

It seems like overkill to you because you know nothing about real storage.

Optical tech has been used for storage interfaces for many, many years (mid-90s was the first time I recall seeing fibre channel SANs).

Absolutely correct. Fiberchannel systems have much higher bandwith than LightPeak\. The poster above is only considering the transfer rate from one hard drive, but on machines with more than 1 drive, or banks of drives providing information, that bandwith becomes essential.

and just how many end users are going to be using JBOD's or multiple at home?

for your average home user, it is overkill

for those of us who do need such bandwidth, we aint giving up fiberchannel anytime soon now are we?

also, being an electrical interconnect instead of the optical we use, distance is very much shortened, rendering it even more useless for those of us who use such connections

I don't know the answer to that, exactly, but I do know folks who have over 10 TB of personal data (mostly media) that this could be useful for.

In the bandwidth department, Thunderbolt beats 4Gb FC interfaces and only 8Gb fiber channel interfaces have a higher bandwidth, so it could handle a bank of drives just fine from a bandwidth perspective. However, this technology is not meant to compete against FC. That said, the cost of a 4Gb FC card, let alone an 8Gb one is very high and outside of the range of the average consumer. Thunderbolt not only sits between 4Gb FC and 8Gb FC from a bandwidth perspective, but it also has the potential of encapsulating multiple protocols (which FC cards can't) at a fraction of the price of a FC interface. You can see why this technology looks like a winner for the consumer.

Actually I'm correcting myself, Thunderbolt has more available bandwidth than 8Gb FC.

Actually Thunderbolt has 2 x 10Gbps (for a total of 20).

Not quite right. The fastest Fiber Channel connections are 8 Gb/s while Light Peak is 10 Gb/s. This is theoretical maximum of course. Who knows what the actual file throughput will be. I guess it depends on how efficient the Light Peak protocol is. Hopefully it doesn't completely suck like USB, where you're lucky if the actual throughput is 50% of theoretical.
