LaCie is a French-American computer hardware company that designs external storage devices for creative professionals, including photographers, filmmakers, and music producers. Originally formed in 1989 as électronique d2 in Paris by Pierre Fournier and Philippe Spruch, the company merged with the Oregon-based La Cie, Ltd. in 1995 and adopted the LaCie name worldwide. Since 2014 it has operated as the premium storage brand of Seagate Technology, while maintaining a distinct identity centered on industrial design and durability.

The company's product line spans portable bus-powered drives, desktop storage, and multi-bay RAID systems with Thunderbolt and USB-C connectivity. The LaCie Rugged series — recognizable for its orange shock-absorbing bumper designed by Neil Poulton — has been a staple of on-location recording and field production since 2005, offering drop, dust, and water resistance for working outside the studio. Higher-end lines include the d2 Professional desktop drive, the 2big and 5big RAID enclosures aimed at video and audio post-production, and the 1big Dock and 2big Dock, which combine storage with card readers and display passthrough for editing workflows.

In music and audio contexts, LaCie drives are commonly used to host DAW session files, large sample libraries, and multi-track recordings, where the brand's RAID arrays provide redundancy for irreplaceable project data and the Rugged line travels with engineers between studios and live dates. Most LaCie storage products ship with included data-recovery service plans, a feature aimed at the working professionals the brand targets.

LaCie has 13 products cataloged on Equipboard, including Computers & Peripherals. Their gear is featured by 56 artists, with the strongest followings in Electronic, Pop, and Hip Hop. Notable users include Deadmau5, FINNEAS, and Skrillex.
