Lucas123 writes: Hard drive maker Seagate today announced an exclusive agreement to acquire a controlling interest in external drive maker LaCie. The all-cash transaction would be worth about $186 million, or $5.17 a share. LaCie Chairman and CEO Philippe Spruch is expected to join Seagate to run its consumer storage products organization. Seagate Chairman Steve Luczo said LaCie's products would compliment Seagate's own drive products and allow it to expand its line by adding a "premium-branded" direct-attached storage (DAS) line. The move will also help Seagate develop better software.
