Provided are a high-performance distributed storage apparatus and method. The high-performance distributed storage method includes receiving and storing file data by a chunk unit, outputting file data chunks stored in an input buffer and transmitting the file data chunks to data servers in parallel, additionally generating a new file storage requester to connect the new file storage requester to a new data server based on a data input speed of the input buffer and a data output speed at which data is output to the data server, re-setting a file data chunk output sequence for a plurality of file storage requesters including the new file storage requester, and applying a result of the re-setting to output and transmit the file data chunks stored in the input buffer to the data servers in parallel.
