View source for SCSI controller

A '''SCSI controller''' is used to connect [[SCSI device]]s to a PC.  Aside from a few completely incompatible versions (e.g. HVD<ref>http://ask.adaptec.com/app/answers/detail/a_id/76/~/can-hvd,-lvd-and-se-devices-be-installed-on-the-same-scsi-controller%3F</ref>), 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<ref>https://en.wikipedia.org/wiki/Parallel_SCSI#Mixing_different_speeds</ref>.

== 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.
