Abstract
The present invention relates to a data storage device and a storage control method based on a log-structured merge tree. The log-structured merge tree comprises a plurality of SST files stored on at least one storage device. The storage control method uses a standardized storage unit to store key-value pairs and uses two different filters to locate the storage units storing the target key-value pair in the SST files, thereby saving memory usage and improving file IO efficiency.
