Abstract
A key-value (KV) storage method and apparatus, the method including receiving a write request, where the write request is associated with writing a first key and a first value, storing the first key in a first memory chip of a solid state drive (SSD), and storing the first value in a second memory chip of the SSD, where an erase count of the first memory chip is less than an erase count of the second memory chip, and creating a mapping relationship between the first key, a physical address of the first key, and a physical address of the first value, where the physical address of the first key indicates that the first key is stored in storage space of the first memory chip, and where the physical address of the first value indicates that the first value is stored in storage space of the second memory chip.
