Embodiment Construction

[0015] The present invention will be further described in detail below through specific embodiments in conjunction with the accompanying drawings.

[0016] The inventive idea of ​​the present invention is based on the difference in read and write speed between ordinary hard disks and solid state hard disks as the principle of functional division of hard disk arrays. The data reading speed of ordinary hard disk is much lower than that of solid-state hard disk; and although the data writing speed of ordinary hard disk is also lower than that of solid-state hard disk, the gap is not too big. In terms of data read and write control, due to the need for data backup, it is necessary to simultaneously write data into the disk-type hard disk array and the solid-state hard disk array, and use the control mechanism of reading from the solid-state hard disk by default when reading data.

[0017] Such as figure 1 In the system structure shown in Embodiment 1 of the present invention, the...

Abstract

The invention discloses a hybrid storage control system and method. By partitioning a hard disc array into a solid hard disc array and a magnetic disc type hard disc array according to different types, and using the solid hard disc array as a default data reading source, data reading speed of a system is increased on condition that security performance of the system is not decreased. In addition the data is written into a normal hard disc in mode of writing-in-order, such that disc head seeking is not necessary during writing operation, and that the speed in writing the data into the normal hard disc matches with the speed in writing the data into the solid hard disc, thereby further improving the speed of data writing. The invention is applicable for a variety of storage systems both including the solid hard disc and the magnetic disc type hard disc.

Description

technical field [0001] The invention relates to a data storage method and device, in particular to a storage method and device using a hybrid solid state hard disk and a common hard disk as storage media. Background technique [0002] The storage technology in the prior art is developing rapidly, and a process of gradually converting from a common hard disk as a storage medium to a solid-state hard disk as a storage medium has begun. The storage device in an ordinary hard disk is a disk coated with a magnetic substance, and the storage device in a solid-state hard disk is a flash memory chip. Ordinary hard drives have the advantages of large storage capacity and low price; solid-state drives have the advantages of fast read and write speeds. In current electronic devices, a configuration mode in which the two coexist has appeared, and different data are stored in different hard disks. [0003] RAID (Redundant Arrays of Independent Disks, redundant array of disks), referred...
