In order to improve performance of file system, an effective adaptive file system (EAFS) is proposed, which has mixed structure of RAID3 and RAID5, and this file system tries to reduce the I/O overhead and improve file write performance by reorganizing data in two buffers according to their activities to reduce and amalgamate the write times; further it adopts an adaptive striping of files across multiple disks to get better I/O performance. Research shows that this file system can fit both transaction applications and multimedia applications adaptively. And when the file system load is low, files are striped aggressively to minimize response time, contrariwise less file is striped aggressively to maximize aggregate throughput.
