    Abstract: A multi-threshold storage device and method is disclosed herein. The device comprises at least one hard disc drive (HDD), at least one solid state drive (SSD), and a controller electrically connected with HDD and SSD. The controller determines whether to store a file in HDD or SSD according to whether the read/write (r/w) count of the file exceeds a preset r/w count, whether the storage space occupied by the file exceeds a preset storage space, and whether the file is a popular file. The present invention uses multiple thresholds to configure storage positions of files, improve the economical efficiency of file storage and raise the overall performance of a server system.
