But it cannot be connected to a usb 2.0 port since that would then bottleneck the connection speed and consequently lower the data transfer rates. Test with Sysbench So finally we can run tests on the disk drive using sysbench. Open a terminal and navigate to the directory where you would ...
This will display the memory speed in MiB/s, as well as the access latency associated with it. This test measures write speed, but you can add--memory-oper=readto measure the read speed, which should be a bit higher most of the time. You can also test with lower block sizes, which ...
Full speed ISO transactions 由于USB 2.0支持低速(1.5Mbps)/全速(12Mbps)/高速(480Mbps)三种规格的外部设备,为了将全/低速设备对高速设备可用带宽的影响减到最小,在USB2.0集线器中提供了一种事务转换(Transaction Translator)机制,该机制支持在Hub连接的是全/低速设备的情况下,允许主控制器与Hub之间以高速传输所有...
