spanned vs. stripped

Spanned volume - created from free disk space from 2 to 32 combined disks. Data is written to the first disk until it is full, then it will write to the second disk and so on. If one of the hard disks in the spanned volume fails, the entire volume set is lost and needs to be rebuild and restored from backup. A spanned volume is not fault-tolerant. 

Striped volume (RAID 0) - created from free disk space from 2 to 32 combined disks. When data is written to a striped volume set with 2 disks, the first block is written to the first disk, the second block to the second disk, and the third data block is written to the first disk, and so on, spreading the data evenly over all disks. A striped volume provides he best performance for Windows 2000 systems. A striped volume is not fault-tolerant and cannot be extended once it is created. If one of the hard disks in the striped volume fails, the entire volume set is lost and needs to be rebuild and restored from backup.
