A SCSI controller is used to connect SCSI devices to a PC. Aside from a few completely incompatible versions (e.g. HVD[1]), SCSI is typically backwards compatible right back to the earliest devices. Depending on the standard implemented by a device, it may be interoperable with faster devices on the same bus, or all devices may slow to match the slowest device. If all devices are LVD (80MB/sec or faster) then they will all run at their individual maximum speeds, up to but not exceeding the maximum speed of the controller. However the addition of a single SE device (40MB/sec or less) will cause all devices to drop back to SE speed[2].

Devices

This is a list of all SCSI controller cards in the wiki. This list also includes composite devices, which are cards that perform other functions as well, such as a sound card with a built-in SCSI controller.
