+The naming scheme generally combines the connector type with the number of pins. [[https://en.wikipedia.org/wiki/IDC_(electrical_connector)|IDC (Insulation Displacement Connector)]] is commonly used with flat ribbon cables, with the connector crimped directly onto the cable. Centronics-style connectors are a type of [[https://en.wikipedia.org/wiki/Micro_ribbon_connector|micro-ribbon connector]], typically used with round, insulated external cables rather than flat ribbon cable. [[https://en.wikipedia.org/wiki/Very-high-density_cable_interconnect|VHDCI (Very High Density Cable Interconnect)]] is a smaller, higher-density connector format, also typically used with round, insulated cables. The terms used in this table describe the physical connector rather than the SCSI standard or bus generation; the same connector type may have been used with multiple generations of SCSI.

+===== Drive Height Legend =====
+This legend corresponds to the //Height// column in the tables below.
+.25 inch drive bays come in two heights; full-height and half-height. Full-height bays — seen primarily in much older computer devices — measure 5-3⁄4 inches (146.1 mm) wide and 3-1⁄4 inches (82.6 mm) tall. Half-height bays are still present in many modern computer systems, have the same width as their counterparts, but are only 1-5⁄8 inches (41.3 mm) tall. Many computer cases that have two or more half-height bays available can accommodate full-height drives, although this is not always the case.
+.5 inch drive bays also have two height standards. Full-height bays measure 4 inches (101.6 mm) wide and 1-5⁄8 inches (41.3 mm) tall, the same height as half-height 5.25 inch drive bays. Slim-height bays are the same width, but are shorter at 1.028 inches (26.1 mm)(([[https://en.wikipedia.org/wiki/Drive_bay|Wikipedia — Drive bay]])).

+=== Notes ===
+  * While many external drives are simply internal drives in an enclosure, some are more customized or are missing the front bezel that would be present on a standard internal drive. Keep this in mind if purchasing an external drive in order to shuck the inner drive from it.
+  * Special attention should be paid to the [[reference:manufacturers#pinnacle-micro|Pinnacle Micro]] //Vertex// and //Apex// drives as they are the only drives that support [[extras:Glossary#omdr|OMDR]] disks((citation needed)).
+  * Many models of [[reference:manufacturers#maxoptix|Maxoptix]] drives are difficult to find images of, so some data has been collected from auction listings, old sales lists, and other sources(([[https://web.archive.org/web/20230602055846/http://www.mctk.com/maxoptix.html|Micro Technologies — Maxoptix Optical Drives]])).
+  * The //Star// model variants of some Maxoptix drives seem to have improved caching and other reliability features(([[https://web.archive.org/web/20201123161626/https://www.zsource.com/maxoptix-t6-t5.shtml|ZSource — Maxoptix T6-5200 / T5-2600]])).
+  * The //Maxoptix T7-9100// appears visually similar to and may be a rebadged //Sony SMO-F561//.
