I want to setup a level 0 RAID. Which stripe and clustersize should I use?
It depends on what the array is going to be used for. In general if the array is used for very large files (Video streaming etc.) a larger stripesize is better. For mainstream usage (office, gaming etc.) a stripe and clustersize in the 8-32 kB range is a common choice. To some extend the optimum stripe and clustersize combination also depends on the RAID controller and drives. Quoted FROM TomsHardware.
