of RAID into AMD's RS780 and SB700 chipsets. The HP Compaq dc5850 Business PC products incorporate RAID drive support through factory configurations.

Basic RAID Types This section provides a brief explanation of the supported RAID configurations for HP Compaq dc5850 Business PCs. RAID 0 with two hard drives (Striped) Even though HP supports RAID 0, it is not - HP Dc5850 | AHCI and RAID on HP Compaq dc5850 Business PCs - 2nd Edition - Page 5
chunks or strips, and stored across the stripes of the hard drive members of this RAID volume. To better illustrate the concept of RAID 0 and striping, the following graphic shows how a sequence of data "ABCD..." is stored in a RAID 0 mode. In this example, each letter represents a segment or strip - HP Dc5850 | AHCI and RAID on HP Compaq dc5850 Business PCs - 2nd Edition - Page 6
The HP Compaq dc5850 Microtower also allows for RAID 0 with three hard drives. However, reliability is less than a RAID 0 configuration with two hard drives. RAID 0 with three hard drives is shown in the following figure: Figure 2 RAID 0 - Three hard drives RAID 1 with two hard drives (Mirror) - HP Dc5850 | AHCI and RAID on HP Compaq dc5850 Business PCs - 2nd Edition - Page 7
various pieces are replicated for both of the hard drives; hence, if any one member of the RAID 1 volume fails, the information is kept in the surviving members. After a hard drive failure, the user interface sends a notification so the failed hard drive can be replaced.

The HP Compaq dc5850 Business PC products support two other RAID configurations: • Two hard drive configuration. • Two equal size/type SATA hard drive RAID configurations in RAID 0 or RAID 1. • Maximum of two SATA optical drives. • Three hard drive configuration (only on HP Compaq dc5850 Microtower - HP Dc5850 | AHCI and RAID on HP Compaq dc5850 Business PCs - 2nd Edition - Page 10
Unsupported configurations The HP Compaq dc5850 Business Desktop PC products only support the best user experience and highest possible reliability. As a result, HP does not support the following combinations of RAID hard drives: • Different sizes. • Different speeds (5400 rpm, 7200 rpm, etc.). • - HP Dc5850 | AHCI and RAID on HP Compaq dc5850 Business PCs - 2nd Edition - Page 11
