According to another example, the interface (5) may be an SD or micro SD card interface, and comprise at least one data transfer connector and at least one power supply connector, the data transfer and power supply connectors being in a format compliant with one of the SD card standards (SD, mini SD, and micro SD) as developed by the SD Card Association (SDA), and/or their evolutions. When the interface (5) is of the SD card type, the interface drivers are also configured to comply with one of the existing SD card standards and/or their evolutions.

The device (1) may be implemented in software form, in which case it takes the form of a program executable by a processor, or in hardware form, such as an application specific integrated circuit (ASIC), a system-on-chip (SOC), or in the form of a combination of hardware and software elements, for example a software program intended to be loaded and executed in a FPGA (Field Programmable Gate Array) type of component. The systems-on-chip (SOC) are embedded systems that integrate all components of an electronic system into a single chip. An ASIC (Application-specific Integrated Circuit) is a specialized electronic circuit that groups custom functions for a given application. ASICs are usually configured during manufacture and can only be simulated by the user. Programmable logic circuits of the Field Programmable Gate Array (FPGA) type are electronic circuits that are reconfigurable by the user.

The data storage device (1) may also use hybrid architectures, for example architectures based on a CPU+FPGA, a GPU (Graphics Processing Unit), or an MPPA (Multi-Purpose Processor Array).

Depending on the embodiment, different architectures of the data storage device may be adopted, both for the hardware part of the device and for the software part of the device, where appropriate.
