“Configuring SATA or SAS RAID functionality with the Intel RSTe configuration utility” on page 44

Installing SATA or SAS hard disk drives

Ensure that your computer has the minimum number of SATA or SAS hard disk drives installed for the following supported levels of RAID:

RAID Level 0 - Striped disk array

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

Supported strip size: 4 KB, 8 KB, 16 KB, 32 KB, 64 KB, or 128 KB

Better performance without fault tolerance

RAID Level 1 - Mirrored disk array

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

Improved reading performance and 100% redundancy

RAID Level 10 - Striped and mirrored disk array (a combination of RAID Level 0 and RAID Level 1)

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

Supported strip size: 4 KB, 8 KB, 16 KB, 32 KB, or 64 KB

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: 4 KB, 8 KB, 16 KB, 32 KB, or 64 KB

Better performance and fault tolerance

Ensure that one of the following hard disk drive enablement modules is installed in your computer:

If zero to four SATA hard disk drives or solid state drives are installed, no hard disk drive enablement module is needed.
