Features: brand new and high quality Shape: 80PCB board end, built-in adapter card. Pitch: SCA80 female terminal 1.27 (mm) IDE50 male terminal pitch 2.54 (mm). A host adapter and eight SCSI peripheral controllers can be connected to the SCSI bus. Peripherals can include disks, tapes, CD-ROMs, rewritable optical drives, printers, scanners, and communication devices. SCSI is a multitasking interface with bus arbitration function. Multiple peripherals connected to a SCSI bus can work at the same for time. Devices on SCSI have equal possession of the bus. The 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.
