Stacked-device peripheral storage card

A data storage card, comprising:

• a circuit board;
• a plurality of storage drive connectors coupled to the circuit board, wherein a drive connector height of a first set of the storage drive connectors comprises a different height in a vertical axis perpendicular to the surface of the circuit board than a drive connector height of a second set of the storage drive connectors;
• and
• a switch circuit configured to communicatively couple to signaling of the plurality of storage drive connectors and signaling of a host interface of the data storage card, receive storage operations over the host interface and transfer the storage operations for delivery over associated ones of the storage drive connectors.

A half-height, half-length (HHHL) Peripheral Component Interconnect Express (PCIe) storage card insertable into a PCIe slot of a host system, comprising:

• a circuit board;
• at least four storage devices comprising at least two upper storage devices having a first distance with respect to a surface of the circuit board and stacked above at least two lower storage devices having a second distance with respect to the surface of the circuit board, each of the at least four storage devices comprising an associated device PCIe interface and solid state storage media, and configured to store and retrieve data responsive to storage operations received over the associated device PCIe interface;
• a PCIe switch circuit communicatively coupled to the device PCIe interfaces and configured to receive the storage operations issued by the host system over a host PCIe connector of the PCIe storage card, and transfer the storage operations for delivery to selected ones of the at least four storage devices over the associated device PCIe interfaces;
• and
• holdup circuitry configured to provide power to the at least four storage devices after input power is lost to the PCIe storage card.
