USB SuperSpeed 3.0-to-SATA Controllers Targeting Consumer Storage

PLX Technology announced the sampling of three USB SuperSpeed 3.0-to-SATA controllers targeting the consumer storage market. The new PLX trio includes the OXU3102, OXU3101 and OXU3100, which are said to provide the highest performance of direct attached storage (DAS) products using the USB SuperSpeed standard. The OXU3102 DAS controller targets the “prosumer” (professional- and power-consumer) market segment and combines USB SuperSpeed’s 5 Gbps interface with dual high-speed SATA hard disk drive (HDD) ports. The midrange OXU3101 for portable computing and desktops offers the same features but bridges to a single SATA HDD. Both the OXU3102 and OXU3101 feature integrated AES-256 encryption/decryption capabilities to ensure high levels of data security. The entry-level OXU3100 provides the essential features for basic SuperSpeed-to-SATA designs. The company asserts the OXU3101 is 8MB/s faster than the closest solution for single-disk systems. All three devices are strengthened with support for USB Attached SCSI (UAS. The OXU3102 is capable of saturating the USB 3.0 link, owing to hardware RAID 0 (or disk striping) where the data is split across the HDDs, and each HDD is accessed in turn to maximize throughput and reduce bottlenecks. Up to 27 integrated general-purpose I/O (GPIO) ports allow designers to customize their products.
