Abstract

The invention relates to a storage device of an SATA Express interface. The storage device comprises an interface connector, a first control unit and a second control unit. The interface connector comprises a first data connection end, a second data connection end and a control end, wherein two connector detection pins are defined in the pins of the control end, the first data connection end is defined by the first control unit to transfer the data of a first storage according to a first transfer protocol or a second transfer protocol, the second data connection end is defined by the second control unit to transfer the data of a second storage according to the first transfer protocol or the second transfer protocol, and by detecting the two connector detection pins, whether the data transferred by the first data connection end or the second data connection end accord with the first transfer protocol or the second transfer protocol or not can be judged.

Description

【Technical field】 [0001] The present invention relates to a storage device and its inserted motherboard, especially a storage device conforming to the SATA Express interface specification and its inserted motherboard. 【Background technique】 [0002] The performance of solid-state hard drives is constantly improving, so that the current bandwidth transmission speed of SATA is not enough. For example, the bandwidth transmission speed of SATA3 is 6Gb / s. Here, in order to further improve the bandwidth transmission speed of SATA, the SATA-IO Association has developed a new SATA Express interface specification based on the PCI-Express interface, and its bandwidth transmission speed can reach 8Gb / s or 16Gb / s . [0003] The SATA Express interface specification allows the interface to be configured with one or two storages, and the storages can be solid state hard drives or flash memory modules. The pin definition of the SATA Express interface is described in Table 1: [0004] ...
