A PCI-E bus standard compliant multifunctional interface board includes a substrate, a PCI-E connector, a storage device, a non-storage device and a signal dispatch device. The PCI-E connector is provided on the substrate and is configured to be electrically connected to a host. The storage device and the non-storage device are provided on the substrate. The signal dispatch device is provided on the substrate and includes: an upstream port, a downstream port and an I/O controller. The upstream port is electrically connected to the PCI-E connector. The downstream port is electrically connected to the storage device and/or the non-storage device. The I/O controller is electrically connected to the upstream port and the downstream port to control an electrical connection relationship between the host and the storage device and/or the non-storage device.

The invention provides a data protection method, which is applied in a data storage device. The data storage device comprises a controller and a plurality of flash memories. The flash memories are formed with a data storage area. When the user wants to protect at least one specific data in the data storage device, a write filter command is transmitted to the data storage device by a host. After the controller of the data storage device receives the write filter command, it will execute a write filter process. When the write filter process is performing, the data storage area is cut into a first partition and a second partition by the controller, and sets the first partition as a read-only area for prohibiting the movement of data, so that the specific data stored in the first partition can be protected by prohibiting the movement of data.

Data protection method

An estimation method for read and write access performance adapted for a computer system including a host and a flash memory device is disclosed. The flash memory device includes a controller, and a flash memory module having a plurality of blocks. When the host transmits a writing performance query instruction, the controller executes a writing performance estimation process including determining whether at least one free block can accommodate data to be written. If Yes, a reply signal including an optimal writing performance is transmitted to the host; and if No, at least one block having data stored therein is selected for execution of a garbage collection process. When the host transmits a reading performance query instruction, the controller executes a reading performance estimation process including determining a threshold interval within which an average retry times of shift read is located to determine a corresponding estimated reading performance.

The present invention relates to a data connector, particularly a SATA Express connector having a power supplying line, the SATA Express connector including a device-side connector and a board-side connector, where the device-side connector is provided with at least one second device-side connector and a first device-side connector, which includes a power receiving pin, a PERST# pin, a CLKREQ#/DEVSLP pin and an IFDet pin, the board-side connector is provided with at least one second board-side connector and a first board-side connector, which is correspondingly provided with a power supplying pin, a PERST# pin, a CLKREQ#/DEVSLP pin and an IFDet pin; when the device-side connector is engaged with the board-side connector, the power supplying pin of the board-side connector provide a working power source through the device-side connector to an application component, and thus transmission of SATA or PCIe data can be carried out without additionally providing an external power cable.

SATA express connector

A SATA data connector is provided with a power supply circuit. The SATA data connector comprises a male data connector and a female data connector. The male and female data connectors includes a signal interface having seven data connection pins. The male and female data connection pins each consist of four data pins, a power supplying pin or power receiving pin, and two ground pins, wherein the power supplying pin connects with a power line of a circuit board. Mating the female data connector to the male data connector causes an operating power to be supplied from the power line of the circuit board to an applied device connected to the female data connector such that the SATA data connector can work without an external SATA power cable.

SATA data connector

A modified standard SATA data connector is provided with a power supply circuit. The connector includes male and female data connectors. A male signal interface has seven male data connection pins, consisting of four data, a power supply, and two ground pins, the power supply pin replacing one of three original ground pins and connecting with a power line of a circuit board. A corresponding female signal interface has seven female data connection pins consisting of four data, a power receiving, and two ground pins. While the female and male data connectors are engaged, power can be supplied from the power line of the circuit board to an applied device connected with the female data connector via the power supplying and receiving pins. Thus, the SATA data connector can work without an external SATA power cable, and the volume of the cable can be reduced.
