step S4: the data of the original file is stored into the plurality of files of fission, and step S2 is performed.
Specifically, in some embodiments, the method for storing and accessing data by the hard disk comprises the following steps:
step S1: based on a hash self-defined grouping algorithm, uniformly dividing data to be stored into a plurality of files of a hard disk;
step S2: the file path enters a data storage maintenance center, and the data format is as follows: { file path: file, amount of data stored for file }. Wherein, the file stores a line of information as a datum;
step S3: when the data volume stored in the file reaches a threshold value, upgrading the current file path to a directory, and fission a plurality of files under the current directory;
step S4: based on a hash self-defined grouping algorithm corresponding to a directory hierarchy, data of an original file are uniformly distributed into a plurality of fissile files, a path of each fissile file enters a data storage maintenance center, and the data format is as follows: { fissured File Path File, amount of data stored for File }.
Wherein, the data storage maintenance center records the number of data, namely { the path of the file after fission: the file, the data amount of the file storage }.

step S4: meanwhile, 5000 data are evenly distributed into 1000 txt texts which are newly added by using a hash-1000 _2 algorithm corresponding to the directory hierarchy, and the newly added text path is changed into the following paths in the data center: { data/1/1: File, 1 };
step S5: when information is searched according to a user name, acquiring a path under which the user name falls according to a hash _1000_1 algorithm, and then sending the user name to a data storage maintenance center to acquire whether the current path is a file;
step S6: if the current path is a file, selecting a corresponding hash-1000 _2 algorithm according to a default directory hierarchy, and then addressing the path until the current path is a file;
step S7: when the acquired user name is stored in a specific file, the file contents are all read in batch, and then comparison is carried out for 5000 times to accurately position the user.
