## Abstract

An interface is provided to adjust a storage setup based on speed and/or capacity. The interface includes a controller that manages downstream peripheral component interconnect express (PCIe) lane configurations. A splitter may split a PCIe lane into multiple configurations based on a configuration of the controller. An adapter includes a set of slots for inserting storage devices to convert the first PCIe lane configuration to the second PCIe lane configuration. The slots on the adapter may split a one storage device to four PCIe lanes (1×4) connector to two separate connectors, each operating at a speed of two storage devices to two PCIe lanes. The slots on the adapter may also split the one storage device to four PCIe lanes (1×4) connector to four separate connectors, each operating at a speed of four storage devices to one PCIe lane.
