Abstract: The present invention relates to a method of improving file write performance and providing availability in a hybrid storage system. When a file writing target server information request signal is received from a client, any one cache server is selected in consideration of storage spaces of cache servers, information about the selected cache server to the client is transmitted so that the client stores the file in the selected cache server. When a duplicate writing target server information request is received from the selected cache server, any one first data server is selected in consideration of storage spaces of respective data servers, information about the selected first data server is transmitted to the cache server so that the cache server stores a duplicate of the file in the first data server. Information about storage of the file and the duplicate is received, and then file metadata is stored.
