Thunderbolt has a new accessory. By LaCie. One *not* made by Apple!

Thunderbolt fans scouring shelves and online stores for a new Thunderbolt-compatible product can add a long-awaited option to their wishlist, as LaCie announced its Thunderbolt-compatible Little Big Disk is now available.

Thunderbolt is the high-speed connection designed by Intel Corp. and Apple Corp. to be a new-fangled, USB-busting, desktop storage technology with 10 Gbps of bandwidth over a cable. The technology also allows a monitor to run simultaneously with a storage device on a single cable (the cables go for $49 at the Apple Store).

LaCie’s pair of Little Big Disk external SSD offerings – a 500 GB unit for $1,499.95 and a smaller 250 GB unit for $899.95 at the Apple Store – are aimed at professionals dealing with video and media that involve large files.

Right now, the only way to use Thunderbolt is by picking up a new Apple computer, as Thunderbolt-compatible Windows PCs haven’t yet hit the shelves, even with Intel’s involvement.
