LaCie introduced his Little Big Disk consisting of two SSD in RAID 0 using the Thunderbolt connections. It is the first time that a builder shows the performance of its devices. Flows have reached more than 820 MB/s read and more than 350 MB/s write. SlashGear has published a video of the presentation, says the company to have reached 870 MB/s. In comparison, an identical configuration using FireWire 800 enclosures offers 80 MB/s read and 75 MB/s write.
The tests turned on a MacBook Pro Core i7 which also could turn three videos 1080p simultaneously without any slowdown. The computer was connected to two Little Big Disk, external housings of each two SSD in RAID 0. They were chained together and the last of the media was linked to a 24 inch screen.
In addition to showing an impressive level of performance than what is achieved with some Fibre Channel solutions, LaCie has attempted to clarify the public targeted by the first goods Thunderbolt. As shown in the video, the representative of the manufacturer spoke primarily mobile post-production. Instead of working on a desktop computer, it is possible to make the Professional Edition of video and editing of film directly to the scene of the shooting.
First Thunderbolt devices should be expensive. As we discovered on the site of Apple, the Pegasus R4 of Promise is expected to cost 1 €100. It is expensive for an individual and it remains expensive for a professional, especially cables are not included, but can much more easily justify the investment. While enthusiasts still dream of having better performance, little really need more than 800 MB/s read throughput. It is very likely that over time, prices will be drawn down and will be sufficiently interesting to start to be accessible to large audiences.
The Thunderbolt is presented by Apple and Intel bus that uses a Mini Display Port port. It provides a flow of 10 GB/s and power of 10 W devices (see "Thunderbolt: 10 gigabits/s, 10 W, Light Peak").
