Disk Striping
Disk striping lets you write data across multiple drives instead of just one drive. Disk striping
involves partitioning each drive storage space into stripes that can vary in size from a minimum
of 64 KB to 1 MB for MegaRAID controllers and 64 KB for Integrated MegaRAID controllers. The
LSISAS2108 controller allows stripe size from 8 KB to 1 MB. These stripes are interleaved in a
repeated sequential manner. The combined storage space is composed of stripes from each
drive. It is recommended that you keep stripe sizes the same across RAID drive groups.
For example, in a four-disk system using only disk striping (used in RAID level 0), segment 1 is
written to disk 1, segment 2 is written to disk 2, and so on. Disk striping enhances performance
because multiple drives are accessed simultaneously, but disk striping does not provide data
redundancy.
