Ultra2WideSCSI
Ultra2WideSCSI, also known as LVD/SE (Low Voltage Differential / Single-Ended), is a version of the SCSI (Small Computer System Interface) parallel bus standard. It was introduced in the late 1990s as a successor to UltraSCSI standards. A key feature of Ultra2WideSCSI is its support for both Low Voltage Differential (LVD) and Single-Ended (SE) signaling modes. This dual-mode capability allowed for backward compatibility with older SE SCSI devices while also offering the significant performance and cable length advantages of LVD.
Ultra2WideSCSI operates at a speed of 80 megatransfers per second (MT/s). The "Wide" designation indicates that
The LVD signaling uses differential signaling, which is more resistant to electrical noise and signal degradation,
