Marvell RAID Utility User Guide

4 SELECTING A RAID LEVEL
Redundant array of independent disks (RAID) is a storage technology consisting of one or
more disks working in parallel. RAID technology allows an array of physical disks to be
combined together to form a logical drive, which appears as a single storage device to the
user.
You can configure a RAID logical drive in several different ways, with each configuration
offering its own benefits. The Marvell RAID controller supports RAID 0, RAID 1, and RAID 10.
This chapter provides information about the properties of each RAID level and how to choose
a suitable RAID level.
The topics included in this chapter are:
 RAID 0 (Striping)
 RAID 1 (Mirroring)
 RAID 10 (Mirroring and Striping)
 Comparing RAID Levels
