Abstract

The invention discloses hard disk storage equipment integrated with a battery and a DRAM. The method comprises steps as follows: the DRAM (dynamic random access memory) is integrated with a traditional hard disc or a solid hard disc, a rechargeable battery is used for supplying battery, the traditional hard disc or the solid hard disc is adopted as a back-up permanent storage device, and the DRAM is ordinarily adopted as a main storage component. When the power is cut off or the data size stored in the DRAM exceeds a pre-set threshold value, the data in the DRAM is written in the traditional hard disc or the solid hard disc. Compare with the prior art, the hard disk storage equipment has the advantages that data writing and reading speed is quick, the hard disc service life is prolonged, and data loss and physical damage caused by unexpected power failure can be avoided. The invention discloses a hard disc storage device integrated with battery and DRAM.

Description

Technical field [0001] The present invention relates to data storage technology, in particular to a hard disk storage method and device combined with battery DRAM (Dynamic Random Access Memory). Background technique [0002] Throughout the development of hard disks in the past ten years, the capacity of traditional hard disks has experienced the development of 100M to terabytes, and the interface mode of traditional hard disks has also experienced from UDMA33 (a type of parallel hardware drive interface) to SATA2 (second-generation serial The hardware drive interface) has been replaced by several generations, and the storage method has been innovated from vertical recording technology to perpendicular recording technology. This shows that traditional hard drives have made considerable progress in both capacity and read / write speed. However, because the working principle of traditional hard disks is always that the magnetic head records data on the magnetic medium by mechanical m...
