Abstract
The utility model provides a design scheme of a mobile storage device with high storage, high density and high reliability, and a control method thereof. The mobile storage device with high storage, high density and high reliability will provide a novel storage scheme with high personal reliability and low cost, and will be widely used in storage application of personal household. Being different from the features of a mobile hard disk, the mobile storage device provides high storage data reliability, while, on the other hand, is not entirely similar to an RAID (Redundant Arrays of Inexpensive Disks) device. The mobile storage device belongs to a small pocket-size and portable mobile device, and can perform simple mobile hard disk and mobile flash disk operation functions at the same time and also perform a storage function of the simple RAID for storage needs of different data, thereby helping to ensure the high reliability of the data storage and meet mass storage needs of low costs at the same time.
Description
Technical field
The invention relates to mobile personal high storage density high reliability and low cost information recording device.
Background technology
Portable hard drive (Mobile or external hard disk) is to be storage medium with the hard disk, exchanges Large Volume Data between the computing machine, stresses portable storage products.Most portable hard drives all is the basis with the standard hard drive on the market, and what have only part seldom is with miniature flash memory disk, but price factor is determining the main flow portable hard drive still to be the basis with standard notebook hard disk.Because adopt hard disk to make, so portable hard drive is identical in the data write pattern with the standard IDE hard disk for storage is situated between.Portable hard drive adopts transmission speeds such as USB, IEEE1394 interface faster more, and speed that can be higher and system carry out data transmission.The reading speed of 2.5 inches brand portable hard drives of main flow is about 15-25MB/s at present, and writing speed is about 8-15MB/s.
Portable hard drive can provide sizable memory capacity, is a kind of mobile storage product than the tool cost performance.Under high capacity " flash memory disk " price also can't be by the situation that the user accepted, portable hard drive can offer bigger memory capacity of user and good just property in user's acceptable Price Range.
Portable hard drive in the market can provide 320GB, 500GB, 750GB, 1TG, and 1.5TB 21TG, 3TG etc. reach as high as the capacity of 10TB, can be described as USB flash disk, the upgrade version of flash memory products such as disk.Accepted extensively by masses.The capacity of portable hard drive is a unit with MB (million) GB (1,024 million) TB (1TB=1024GB) equally.
3.5 the mobile hard disc box of inch also has the high capacity of 500GB, 640GB, 750GB, 1TB, 1.5TB, 2TB, in addition also has the portable hard drive of Table top type, capacity more reaches the vast capacity of 10TB.Along with the development of technology, portable hard drive is increasing with capacity, and volume is more and more littler!
Volume is little
The size of portable hard drive (box) is divided into 1.8.2.5 cun and 3.5 cun three kinds.2.5 very little mobile hard disc box can use the notebook computer hard disk, 2.5 cun mobile hard disc box volumes are little in light weight, are easy to carry, and generally do not have external power supply.The portable hard drive overwhelming majority is a USB interface, but because usb function is limited in one's ability, so in fact 2.5 ' hard disk that portable hard drive uses is different with the hard disk that uses on the notebook.Notebook requires hard disk to start fast, so the starting current of notebook hard disk is big, about about 900mA. and the disc that portable hard drive uses is slightly long start-up time, and starting current is smaller, about general 700mA.So if oneself assembles portable hard drive, still need look for dish core .3.5 cun hard-disk cartridge of special portable hard drive version to use the desktop computer hard disk, volume is bigger, and portability is relatively poor relatively.3.5 generally all carry external power supply and radiator fan in the very little hard-disk cartridge.
Transmission speed is high
Portable hard drive adopts USB, IEEE1394, eSATA interface mostly, and the higher data transmission speed can be provided.But the data rate of portable hard drive also receives the restriction of interface rate to a certain extent, especially on the product of USB1.1 interface specification, when transmission larger data amount, with test user's patience.And USB2.0, IEEE1394, eSATA interface are just good relatively a lot.USB2.0 interface transfer rate is 60MB/s, and IEEE1394 interface transfer rate is 50～100MB/s, and eSATA reaches 1.5Gbps between the 3Gbps. portable hard drive is with host exchanging data the time, and the mass file of reading a GB order of magnitude only needs a few minutes.
But the data reliability of present portable hard drive and solid state rash disk is extremely low, and the storage data are prone to lose. the requirement of incompatibility low side individual family mass memory.
Summary of the invention
The present invention is a kind of memory device that the high reliability of multiple storage scheme can be provided simultaneously, and according to different demands and the selection of client to the data reliability, it can provide the selection of the storage scheme of high reliability and low reliability.Thereby the low-cost approach of mass memory and the demand of high reliability have been guaranteed.The serial storage scheme that this programme provided is that the storage scheme with present portable hard drive is consistent in principle.Parallel storage scheme meanwhile provided by the present invention is to be consistent with the storage scheme of Raid in principle.
The another kind of specific function of device of the present invention is: each separate, stored media in the memory device is to intercourse memory contents according to user's instruction.
One of innovative characteristics of the present invention is that device of the present invention can provide multiple storage scheme to supply the user to select according to actual and concrete demand, thereby device of the present invention can be guaranteed and the high reliability and the low cost that have satisfied data storage simultaneously.
