不知道你是否曾碰到过bios里面能够检测到硬盘（I dont know if youve ever touched a BIOS, and you can detect a hard disk inside it） Readers may know, in computer peripherals, especially the interface of the storage device, SCSI interface plays a role in the world too high to be reached. Not only does it represent the advanced technology and performance it has, but it also implies the high prices that it has. The meaning of SCSI is the small computer system interface (SmallComputerSystemInterface), which was first developed in the late 1970s. After continuous development, todays SCSI has been divided into SCSI-1 and SCSI-2, and the latest SCSI-3 three types. But the most popular version at the moment is SCSI-2. First, the type of SCSI 1.SCSI-1 SCSI-1 is the most original version, asynchronous transmission frequency is 3MB/S, synchronous transmission frequency is 5MB/s. Although now almost eliminated, it will also be used in some scanners and internal ZIP drives, using a 25 pin interface. That is to say, if the SCSI-1 device is connected to your SCSI card, there must be 25 to 50 pin interface cable is an internal; if you use an external device, you cannot use any of the internal interface (i.e. internal interface at this time are not available). 2.SCSI-2 The early SCSI-2, known as FastSCSI, increased the frequency of data transfer from the original 5MB/s to 10MB/s by increasing the frequency of synchronous transmission, supporting 8 bit parallel data transmission and connecting 7 peripherals. Later, the WideSCSI supports 16 bit parallel data transmission, and the data transfer rate is increased to 20MB/s, and even 16 peripherals can be connected. This version of SCSI uses a 50 pin interface, primarily for scanners, CD-ROM drives, and old-fashioned hard drives. 3.SCSI-3 In 1995, the birth of a more high-speed SCSI-3, known as UltraSCSI, data transmission rate has reached 20MB/s. It will synchronize the transmission clock frequency to 20MB/s, improve the data transfer rate technology. If 16 bi
