with the rapid development of storage technology, many kinds of storage products and systems have been released, but these products and systems always have some problems such as the performance is not credible, the reliability is not high and so on. In order to better test and evaluate the performance of storage products and systems, we design and implement a distributed Storage Performance Test System called SPTS, which can test the IO performance of file system and disk array. The experience of testing disk array's IOPS and data transfer rate shows that SPTS can provide certain value when customers purchase and use storage products or storage systems.
