10. Western Digital Snaps Up Virident, sTec
Western Digital, a manufacturer of solid-state drives (SSDs) and hard drives, spent more than $1 billion on a pair of acquisitions that stepped up the company's presence in the red-hot flash memory system market.
Most prominent was the announcement in September that Western Digital would buy flash storage developer Virident for about $685 million. While the move strengthened Western Digital's flash storage product portfolio, it was also seen as creating a wedge between Seagate -- Western Digital's arch-rival -- and Virident, which until then had been an important technology and business partner for Seagate. The acquisition was wrapped up Oct. 17.
Earlier in the year, Western Digital struck a deal to buy sTec, an early leader in the SSD market for about $340 million. That acquisition was completed Sept. 17.
