Bridge board with structure for preventing solid state drive module bending and data storage device including the same

A data storage device comprising:

• a bridge board comprising a first connector;
• and
• a data storage board connected to the first connector,
• wherein the bridge board comprises:
• a printed circuit board (PCB);
• a second connector;
• a protocol converter mounted on the PCB to perform a conversion operation converting between a first communication protocol used by the first connector and a second communication protocol used by the second connector, the second communication protocol being different from the first communication protocol;
• and
• a hole formed in the PCB, wherein the PCB has a shape of a concave polygon, wherein the concave polygon comprises:
• a first region comprising a first edge and a second edge, which extends in parallel to the first edge, along a first direction, and a second region comprising a third edge and a fourth edge, which extends in parallel to the third edge, along a second direction perpendicular to the first direction,
• wherein a ratio of a second length of the second edge to a first length of the first edge is equal to or greater than 0.45 and equal to or less than 0.75,
• wherein a ratio of a fourth length of the fourth edge to a third length of the third edge is equal to or greater than 0.35 and equal to or less than 0.7, and
• wherein the bridge board further comprises a third connector disposed along the fourth edge.

A data storage device comprising:

• a bridge board comprising a first connector;
• at least one damper coupled to a data storage board, wherein the data storage board includes at least one hole;
• and
• the data storage hoard connected to the first connector, wherein the bridge board comprises:
• a printed circuit board (PCB);
• a second connector;
• a protocol converter mounted on the PCB to perform a conversion operation converting between a first communication protocol used by the first connector and a second communication protocol used by the second connector, the second communication protocol being different from the first communication protocol;
• and
• a first hole formed in the PCB, wherein the PCB has a shape of a concave polygon, wherein the concave polygon comprises:
• a first region comprising a first edge and a second edge, which extends in parallel to the first edge, along a first direction, and a second region comprising a third edge and a fourth edge, which extends in parallel to the third edge, along a second direction perpendicular to the first direction,
• wherein a ratio of a second length of the second edge to a first length of the first edge is equal to or less than 0.75,
• wherein a ratio of a fourth length of the fourth edge to a third length of the third edge is equal to or less than 0.7, and
• wherein the bridge board further comprises a third connector disposed along the fourth edge.
