Small Computer System Interface (SCSI) is an independent processor standard for system-level interfaces between computers and their peripheral devices (hard disks, floppy drives, optical drives, printers, scanners, etc.).
SCSI interface can transmit data synchronously or asynchronously, the synchronous transmission rate can reach 10MB/s, and the asynchronous transmission rate can reach 1.5MB/s.
The dielectric withstanding voltage is rated at 500V AC, while the insulation resistance is a minimum of 500MΩ. The contact resistance does not exceed 35m, and the operational temperature range extends from -55°C to +105°C.
The SCSI bus is controlled by a host controller which will typically be built into the motherboard, or it can be from a separate expansion card.
The most important things to remember when selecting your SCSI cable is the type of connector required by your devices, and if the location of the cable is internal or external.
