Embodiment 1
[0029] An embodiment of the present invention provides a storage device, figure 1 is a structural block diagram of a storage device according to an embodiment of the present invention, such as figure 1 As shown, the device includes at least two storage units 10, an external interface 20, a control circuit 30, a power management module 80, and a destruction control unit 90, wherein the control circuit 30 includes a wireless receiving circuit 32 and a switching controller 34, at least two One of them is a clear disk in the storage unit 10, and the storage unit 10 for a clear disk includes a clear disk controller 52 and a clear disk storage area 54, and the other of the at least two storage units 10 is a secret disk, which is a secret disk. The storage unit 10 includes a hard disk controller 62 , a hard disk storage area 64 and an encryption module 66 .
[0030] At least two storage units 10 physically exist as a whole for storing data;
[0031] The external interface 20 is use...
Embodiment 2
[0044] figure 2 is a structural frame of a storage device according to a preferred embodiment of the present invention Figure 1 ,like figure 2 As shown, the storage device includes a hard disk switching unit 40 , a clear disk 50 , a secret disk 60 , and a SATA interface 70 . Among them, the SATA interface 70 is equivalent to figure 1 The external interface 20 and the hard disk switching unit 40 in the figure 1 In the control circuit 30, the clear disk 50 and the secret disk 60 are equivalent to figure 1 At least two storage units 10 in it.
[0045] The interior of the hard disk of the storage device in this embodiment is divided into two areas, one area is the clear disk 50 and the other area is the secret disk 60 . The storage device can be connected to an external device through the SATA interface 70 . When the external device is turned on, only one area works, and it starts from the clear disk 50 by default. When the external device is turned on, it can be switched...
