Understanding RAID

In this appendix...

Understanding Drive Segments ........................................................ 80

RAID 0 (Non-RAID Arrays) ............................................................. 80

RAID 1 Arrays .................................................................................... 81

RAID 1 Enhanced Arrays .................................................................. 82

RAID 10 Arrays.................................................................................. 83

RAID 5 Arrays .................................................................................... 84

RAID 5EE Arrays ............................................................................... 85

RAID 50 Arrays.................................................................................. 86

RAID 6 Arrays .................................................................................... 87

RAID 60 Arrays.................................................................................. 88

Selecting the Best RAID Level ........................................................... 89

When you create arrays (or logical drives), you can assign a RAID level
to protect your data.

Each RAID level offers a unique combination of performance and
redundancy. RAID levels also vary by the number of disk drives they
support.

This appendix describes the RAID levels supported by your Adaptec
RAID controller, and provides a basic overview of each to help you
select the best level of protection for your data storage.
