Western Digital has completed the acquisition of sTec, Inc., a developer of enterprise solid-state drives (SSDs). sTec will be integrated into HGST, a wholly owned subsidiary of Western Digital. The acquisition augments HGST's existing solid-state storage capabilities, accelerating its ability to expand its participation in the growing area of enterprise SSDs.

Completion of the sTec acquisition follows HGST's recent purchase of VeloBit, an SSD caching software company, and the proposed acquisition of Virident, a provider of server-side flash storage solutions. Collectively these building blocks expand HGST's presence in the enterprise SSD space, which IDC predicts will grow from $2.5B in revenue in 2012 to $7B in revenue by 2017.
