Silicon Image's SiI5733 provides scalable and secure storage for HDTVs, digital video recorders, and set-top boxes. Hard drives can be encrypted and matched to the chip so they can only work with the matching device. RAID and daisy-chain expansion are transparent to the user, who simply adds more units to the chain. The Sil5733 supports 3-Gbit/s SATA-II and eSATA connections. Pricing for the Sil5733 starts at $5. It's available in a 10- by 10-mm, 80-pin quad flat no-lead (QFN) package. www.siliconimage.com
