Does raid 0 use data striping?
Yes,
RAID 0 is data strpied across disks.
This is a misnomer because RAID 0 does not provide data redundancy. Since any one disk failure will destroy data a RAID 0 volume is less secure than a single drive. The dependibility is 1/n of a single drive where n is the number of drives in the RAID 0 array.
RAID 0 can improve performance but under certain circumstances performance can decrease compared to a single drive. If too small a stripe size is chosen a random read may require multiple drives to seek rather than one. When random read performance is important choose a stripe size twice as large as your average transfer so most transfers will be accomplished on a single drive. If sequential performance is most important choose smaller stripe sizes.
