It is that one of them sets main equipment for hard disk drive (HDD) 2 and non volatile memory drives 3 that above-mentioned driver is set terminal 51a, sets another for slave, so that main frame 50 can be discerned the terminal of each driver respectively.Above-mentioned address management is for example waited by device driver and realizes, possesses following function: in non volatile memory drives 3 is distributed the address space of the above-mentioned memory storage 51 that is assigned with continuation address, form the space, a part of address in certain space below certain address value, distribute another part address space in addition, that form the space that surpasses above-mentioned certain certain address value to hard disk drive (HDD) 2.In addition, the effect of address management is: discern the corresponding of these address spaces that are assigned with and non volatile memory drives 3 and hard disk drive (HDD) 2 physical address separately, when memory storage 51 sends instruction, to I/F portion 4 input physical addresss.
, though in the above-mentioned non volatile memory drives 3 content of storage as above-mentioned be the content of system realm illustrated in fig. 3, therein, particularly as shown in figure 11, also storage file admin table (FAT1,2) and directory information (DIR), thus can realize high speed.In addition, its effect in memory storage of above-mentioned embodiment 1 etc. too.Be described below.
Figure 11 is in the storage system of embodiment of the present invention 5, the address space of the memory storage of expression Figure 10 and the key diagram that is stored in an example of the content in this address space.In Figure 11, in continuous address, distribute " 0h "～" nh " to flash drives (FMD), distribute " n+1h "～" mh " to hard disk drive (HDD) 2.Then, storage file admin table (FAT1,2) and directory information (DIR) in flash drives (FMD).
for example store in this document admin table (FAT1,2) as the sector of the minimum memory unit of flash drives (FMD) or hard disk drive (HDD) 2 and as the minimum management unit of O/S etc., constitute by a plurality of sectors bunch between relation etc.In addition, in directory information (DIR), for example record information such as filename, escape character, size, update date, starting cluster number.Therefore, O/S etc. to memory storage 51 carry out data read/write fashionable, successively with reference to this document admin table (FAT1,2) and directory information (DIR).
But, under the situation that storage this document admin table (FAT1,2) waits in hard disk drive (HDD) 2, because it searches time or retrieval time, the responsiveness reduction.Therefore, if this document admin table (FAT1,2) etc. is stored in the flash drives (FMD), then can solves such problem, and as shown in figure 12, can seek high speed.
Figure 12 is in the storage system of embodiment of the present invention 5, expression is by being stored in file management table etc. the key diagram of an example of the effect that realizes in the non volatile memory drives, (a) expression is stored in the write time under the situation in the non volatile memory drives, and (b) expression is stored in the write time under the situation in the hard disk drive.Figure 12 (a) (b) in, utilize the super DMA (U1tra-DMA (direct memory access (DMA) of 133M byte per second, Direct Memory Access)) transmit, from RAM50a the data that hard disk drive (HDD) 2 carries out the 100K byte are write, before and after this writes, between CPU5 and hard disk drive (HDD) 2, produce PIO (program I/O (Program I/O)) and transmit.
In Figure 12 (b), file management table (FAT1,2) and directory information (DIR) are arranged in hard disk drive (HDD) 2, need the time about 10ms in the PIO of these information transmits respectively.Thus, the write time of 100K byte is about 71.1ms.On the other hand, in Figure 12 (a), file management table (FAT1,2) and directory information (DIR) are arranged in flash drives (FDM), and the PIO transmission of these information is respectively 0.01ms～0.2ms and gets final product.Thus, the write time of 100K byte is about 17.8ms, compares with Figure 12 (b), can realize the high speed about 4 times.
In addition, think when reading, also can obtain same effect, can estimate the high speed about 3～4 times.In addition, when power connection/disconnection, because especially concentrated,, thereby can shorten starting time etc. of O/S significantly so the effect of high speed is more obvious to the access of hard disk drive (HDD) 2.
Like this, by storage file admin table in non volatile memory drives 3 (FAT1,2) and directory information (DIR), can realize high speed.And on this basis, the Main Boot Record (MBR) by storage map 3 or partition boot record (PBR) etc. also can obtain high reliability.And think that the capacity that file management table (FAT1,2) and directory information (DIR) and Main Boot Record (MBR) or partition boot record (PBR) etc. relate to the data of file management is less than or equal to the 128M byte and gets final product.Therefore, in non volatile memory drives 3, do not comprise O/S or application program, only store under this data conditions that relates to file management, can realize high reliability and high speed yet, and, because capacity can be less, so can suppress the increase of cost.
In addition, the storage system of Figure 10 is compared with the structure of memory storage shown in Figure 2, that possess Fig. 1, owing to do not need driver selection portion 1 hardware such as grade of Fig. 1, so particularly aspect cost, we can say easy realization.
