Features
1. Compliant to USB3.0 specification
MB86C311 solution complies with USB3.0, 5Gbps that provides a maximum of over 10 times the data transfer rate of USB 2.0. The maximum transmission speed of USB3.0 allows for example 10GB to 30GBytes of video data to be copied to a 3.5 inch hard disk drive in 1/4 to 1/3 the time compared to the existing USB2.0 interface.
2. UAS (USB Attached SCSI) protocol
86C311 solution supports UAS protocol, which is a new protocol for USB storage devices. UAS enables NCQ (Native Command Queuing) function that can achieve random access performance of SATA device such as HDD and SSD.
3. 1-chip integration of necessary functions for USB storage using SATA device MB86C311 integrates all needed interface blocks and a control block on one chip. Thus it can easily enable to build USB3.0 storage unit with a few peripheral ICs and SATA device, which is HDD or Blu-ray.
