The invention provides a graph construction method and device, a storage medium and computer equipment, and the method comprises the steps: obtaining an original vector graph corresponding to each data vector in a data set; according to the first compression vector of each data vector, constructing a compression vector pool and storing the compression vector pool to a target position; the target position is selected from a memory and a disk according to a preset cooperation strategy; according to the data vectors corresponding to the nodes in the original vector diagram, the node connection relation and the target page node capacity, clustering the nodes to obtain a page node diagram; the page node graph comprises a plurality of page nodes and page connection relations of the page nodes; one page node comprises nodes corresponding to a plurality of data vectors respectively, and different page nodes comprise different nodes; and according to the page connection relationship and the data vector corresponding to each node included in each page node, determining a solid state disk (SSD) page corresponding to each page node.
