Nowadays, videos and images dimensions are improved from 1D and 2D images into 3D or 4D (3 spatial dimension + time) images / videos. The improvement for these video data file were also increased the size of the data. Therefore, single and small storage is not enough for storing them. To overcome the problem, grid-based file storage service is introduced. However, the quality-of-service is very important for this applications and service. Therefore, several of quality-of-service requirements such as delay for data transmission, average CPU time per chunk used, and the total download time for a complete video file are need to be investigate. In this paper, our grid-based file storage test bed architecture, and the previous existing multimedia file splitting techniques will be discussed. Besides, our new multimedia file splitting technique – “Exponential-And-Uniform-based Splitting Technique” is also being proposed.
