RAID IDE1/ RAID IDE2 (RAID IDE connector => optional)
The PX915PD (GD) PRO II & PX915PD (GD) PRO provide two RAID IDE connectors. These
connectors are capable of sophisticated disk management using RAID 0/1/0+1 and JBOD
modes
（
for more details about RAID configuration, please refer to the ITE RAID
Controller manual
）
. As with the IDE1 connector, you can connect 2 drives to this
connector. If you are attaching a second drive, the first drive must be configured as the
Master with the second drive being the Slave (see hard drive manual for master/slave
configuration specifics). This connector can be only used with hard disk devices.
RAID 0 (disk striping) Striping is a performance-oriented, non-redundant disk storage
technology. With RAID striping, multiple disks are used to form a larger virtual disk. Data
is then striped or mapped across all the physical disks. In this way disk drives can perform
multiple I/O operations in parallel, enhancing performance.
RAID 1 (disk mirroring) With Disk Mirroring there is a redundant disk that mirrors the
main disk. Data that is written to the main disk is also written to the redundant disk. This
redundancy provides fault tolerant protection from a single disk failure. If a read/write
failure occurs on one drive, the system can still read and write data using the other drive.
RAID 0+1 This mode combines both the performance benefits of RAID 0 with the fault
tolerance of RAID 1
JBOD (Just a Bunch Of Disks) This mode provides you with a way to combine many hard
drives to create a larger drive. The JBOD drive will operate with the same functionality as
a standard hard drive.
