 Flat/Ribbon Cables |
These are the standard cables most computers use. They have a 40-pin ribbon cable that has 40-wires for most standard interfaces or 80-wires for the high speed UltraATA. |
 Round Cables. |
These are the newer style cables that do not have a ribbon, instead they use a round cable. This makes the inside of the computer less cluttered and allows for better air-flow inside the case. |
