Man, the consolidation efforts are really heating up. Just days after Cisco forked out a small fortune to acquire Pure Digital, HDD mainstay Western Digital has penned a check for $65 million in cold, hard cash in order to acquire SiliconSystems, Inc. Said outfit is an Aliso Viejo, California-based supplier of solid-state drives for the embedded systems market, and rather than wasting any more time falling behind in the SSD realm, WD figured it prudent to just buy the technology it needed to position itself as a legitimate competitor. WD has already made clear that it hopes to sell SSDs for the netbook, client and enterprise markets, and given that integration will begin "immediately," we're hoping to see some shipping products sooner rather than later.
