    • Various techniques are provided for interfacing external devices with host computer systems. In one example, hard drive parameters may be retrieved from a nonvolatile memory of an external hard drive enclosure device in order to register the external device with a host device while the host device provides a low power level to the external device. Following registration of the external device, the host device may provide a high power level to the external device to operate the registered external device. The hard drive parameters may be stored in the nonvolatile memory by a provider of the external device. In another example, the hard drive parameters may be loaded into the nonvolatile memory by appropriate software running on the host device. In yet another example, the external device may read the hard drive parameters from the hard drive while emulating another external device.

    • Various techniques are provided to support efficient data transfers over serial data streams. In one example, a serial device may be used to efficiently transfer data between a host device and the serial device over a data stream of a serial interface. A data stream value identifying the data stream may be stored in a register indexed by a tag associated with a command received from the host device. The command may be passed to a storage media device, wherein the passing is controlled by a processor of the serial device. The tag may be extracted from an address value received from the storage media device in response to execution of the command by the storage media device. The data stream value may be retrieved from the register using the extracted tag as an index without requiring an interrupt to the processor to determine the data stream value.
    • 提供了各种技术来支持通过串行数据流的有效数据传输。 在一个示例中,串行设备可以用于通过串行接口的数据流在主机设备和串行设备之间有效地传输数据。 识别数据流的数据流值可以存储在由与从主机设备接收的命令相关联的标签索引的寄存器中。 该命令可以被传递到存储介质设备,其中通过由串行设备的处理器来控制。 响应于存储介质设备的命令的执行,可以从从存储介质设备接收的地址值中提取标签。 可以使用提取的标签作为索引从寄存器中检索数据流值,而不需要处理器的中断来确定数据流值。

    • Systems and methods for a mass storage device attached to a host device use speculation about the host command likely to be received next from the host device based on a previously received command to improve throughput of accesses to the mass storage device. Host commands are used to speculatively produce commands for data storage devices of the mass storage device, such that host commands speculated as being likely next can be started during idle time of the data storage devices, based upon the probability that the speculation will be correct some of the time, and otherwise wasted idle time will be more efficiently used. Time taken by the host device to produce successive commands to the mass storage system is monitored, and future speculatively produced commands are parameterized to complete within the observed host time to produce new commands, making more efficient use of the data storage devices.
