supported RAID configurations for HP Compaq dc7800 Business PCs. RAID 0 with two hard drives (Striped) Even though HP supports RAID 0, it is not the recommended configuration for business PC the concept of RAID 0 and striping, the following graphic shows how a sequence of data "ABCD..." is stored in - Compaq dc7800 | AHCI and RAID on HP Compaq dc7800 - Page 6
with two hard drives At a higher reliability cost with faster performance, the HP Compaq dc7800 Business PC Convertible Minitower also allows for RAID 0 with three hard drives. RAID 0 with two or three hard drives is a supported configuration. RAID 0 with three hard drives is shown in the following - Compaq dc7800 | AHCI and RAID on HP Compaq dc7800 - Page 7
1 is the only RAID configuration that HP preconfigures for HP Compaq dc7800 Business PCs. RAID 1 provides high availability with segmentation, and striping have no real meaning in RAID 1. In the table and graphic, the data is arranged in rows for representation of different pieces of data. Table - Compaq dc7800 | AHCI and RAID on HP Compaq dc7800 - Page 8
Figure 3 Reliability: RAID 1 - Mirroring RAID 5 with three hard drives RAID 5 has been used in servers for many years and is one of the most common types of RAID. RAID 5 uses striping with parity data in distributed blocks across all member disks. Therefore, the mass storage controller can - Compaq dc7800 | AHCI and RAID on HP Compaq dc7800 - Page 9
