Western Digital : disque dur externe Thunderbolt pour les créateurs

Western Digital annonce le My Book Thunderbolt Duo, disque dur externe adoptant l’interface Thunderbolt. Clairement destiné aux professionnels, le système comporte un double emplacement pour disques durs Serial ATA 3,5 pouces. Un contrôleur RAID permet de se placer en mode 0 (les deux disques sont vus comme un unique support de stockage avec des performances accrues mais une fiabilité moindre) ou 1 (mode miroir, assurant une bonne fiabilité).

L’utilisation de ports Thunderbolt permet de brancher plusieurs de ces disques en chaîne (jusqu’à six).

Dans la pratique, les taux de transfert semblent excellents, comme en témoigne la vidéo qui suit, tournée depuis MacWorld / iWorld. Le communiqué évoque une vitesse supérieure à 250Mo/s en moyenne pour des systèmes de 6To, 225Mo/s pour 4To.

Le prix et la disponibilité devraient être rendus publics dans les prochains jours.

Pour finir, voici le communiqué complet :



IRVINE, Calif. – Jan. 26, 2012 – (Macworld/iWorld Booth #401) – Western Digital® (NYSE: WDC), the world’s leader in external storage solutions, will demonstrate the ultra-fast data transfer rates of its upcoming My Book® Thunderbolt Duo dual-drive storage system at the Macworld/iWorld show (booth #401). Thunderbolt technology will dramatically improve workflow speed and efficiencies for enthusiasts and professionals dealing with large digital files such as video, audio and still photos.

Thunderbolt technology is capable of producing up to 10 gigabits per second1 of throughput on each of two channels in both directions. Users can experience very fast read/write speeds especially during applications such as video editing, 3D rendering, and other intense graphics projects. To put Thunderbolt’s speed into perspective, HD media creators will be able to transfer a standard size full-length HD movie in less than 30 seconds, or backup an entire year of continuous music (approx. 8,600 hours of music) in roughly 10 minutes.

« Thunderbolt technology offers the speed needed for creative professionals and enthusiasts who produce, edit, or need quick access to large files, including HD video, » said Jody Bradshaw, general manager of WD’s consumer storage solutions. « During the demonstration, twin Thunderbolt ports show amazing flexibility while allowing daisy-chaining of up to six My Book Thunderbolt Duo systems or other high performance peripherals for an enhanced workflow process. The combination of storage, backup, and speed could make the My Book Thunderbolt Duo the only drive a creative pro would ever need. »
