RAID Level 0 - Striped disk array

A RAID Level 0 hard disk drive group consisting of at least one hard disk drive

Supported strip size: 8 KB to 1 MB

Better performance without fault tolerance

RAID Level 00 - Spanned hard disk drive group with a series of RAID 0 hard disk drive groups

A RAID Level 00 hard disk drive group consisting of two or four hard disk drives

Supported strip size: 8 KB to 1 MB

Better performance without fault tolerance

RAID Level 1 - Mirrored disk array

A RAID Level 1 hard disk drive group consisting of two or four hard disk drives

Improved read performance and 100% redundancy

RAID Level 10 - A combination of RAID Level 0 and RAID Level 1

A RAID Level 10 hard disk drive group consisting of four hard disk drives

Data being striped across hard disk drive groups

Provides both high data transfer rates and complete data redundancy

RAID Level 5 - Block-level striped disk array with distributed parity

A RAID Level 5 hard disk drive group consisting of at least three hard disk drives

Supported strip size: 8 KB to 1 MB

Better performance and fault tolerance

RAID Level 5 might not be available on all models of LSI MegaRAID adapter

RAID Level 6 - Block-level striped disk array with dual distributed parity

A RAID Level 6 hard disk drive group consisting of at least four hard disk drives

Supported strip size: 8 KB to 1 MB

Better performance and fault tolerance that can stand up to loss of two hard disk drives

RAID Level 6 might not be available on all models of LSI MegaRAID adapter

Ensure that the LSI MegaRAID SAS adapter card is installed in your computer, and that the hard disk drives are connected to this adapter card and not to the connectors on the system board.
