The invention discloses a data storage method and device, equipment and a medium, and relates to the technical field of computers, and the method comprises the steps: obtaining a data writing request which is sent by a client for a target encrypted volume and comprises to-be-stored data through a distributed storage cluster; writing the to-be-stored data into a cache memory, and obtaining a key pair corresponding to the target encrypted volume from a preset key management system; and encrypting the to-be-stored data in the cache memory by using a public key in the key pair, and writing the encrypted to-be-stored data into a hard disk drive. It can be seen that the data is encrypted through the distributed storage cluster, and the encrypted to-be-stored data is written into the hard disk drive, so that the safety of the data stored in the hard disk drive is ensured, and compared with a traditional mode of encrypting the data through a client before data transmission, the safety of the data stored in the hard d
