Reference: http://blog.csdn.net/tianlesoftware/article/details/6009110The main types of hard disk interfaces currently available are IDE, SATA, SCSI, SAS, FC, and so on.The IDE is commonly known as the port, SATA is commonly known as the serial port, both of the hard disk is the PC and low-end server common hard disk.SCSI is the abbreviation for "Small computer system dedicated interface", which is the hard disk with this interface.SAS is the SCSI interface of the serial port. The general server
that the accuracy rate of YOLO in detecting small targets is about 8~10% than R-CNN, and the accuracy rate is higher than r-cnn in the detection of large targets. The accuracy of Fast-r-cnn+yolo is the highest, and the accuracy rate is 2.3% higher than that of FAST-R-CNN.5.4 SummaryYolo is a convolutional neural network that supports end-to-end training and testing, and can detect and recognize multiple targets in images under the premise of guaranteeing certain accuracy.6.

Design division, Knut Grimsrud said the SATA3.0 transmission rate was 6Gbps.
Now seven years later, the speed of solid-state hard disk has changed dramatically, many excellent SSD read and write speed has reached 550mb/s, this is already the limit speed of SATA3 interface, so many manufacturers choose to develop new interface solid-state hard disk.
