File sized stripes - stored as a unit in the available space. 
  If one disk is full, start filling the next disk. 
  Or each successive file save, stored on next drive. 

  - Looses parallel high speed access of individual files.

  + May allow parallel access of different files. 

  JBOD - not RAID, just a bunch of disks. JBOD also does not provide data 
    protection.

    Dynamic disk storage on NTFS is one of the features of Microsoft's 
      logical volume manager. 

      Dynamic partioning allows several partitions/drives to appear as
      a single very large partition to the NTFS operating system.
 
    Because of the way filesystem record keeping is implemented, a failed
      drive can cause loss of all data in the logical partition (on several
      drives).

    Linux also has a logical volume manager and dynamic partitioning,
      which doesn't work well with ext3 or other journaling filesystems.     

    Dynamic partitioning is OS dependent. 

    Many modern LVMs also provide software implementation of the various
      RAID levels.
