ATA133 RAID Connectors: IDE3 & IDE4
The mainboard offers high-end Ultra ATA/133 RAID (0 or 1) hard drive
interface specifications supported through Promise
The Ultra ATA/133 interface boosts data transfer rates between the com-
puter and the hard drive up to 133 megabytes (MB) per second. The new
interface is one-third faster than earlier record-breaking Ultra ATA/100 tech-
nology and is backward compatible with the existing Ultra ATA interface.
The low-cost RAID (Redundant Array of Independent Disks) solution
integrates two IDE RAID connectors that support PIO mode 0-4, Bus Master,
and Ultra DMA 33/66/100/133 modes. The IDE RAID connectors allow you to
connect Ultra ATA/DMA hard disks and use RAID technology (RAID 0 strip-
ing or RAID 1 mirroring) for high performance, data security and fault tolerance.
ATA133 RAID Connectors:
- You can connect a Master drive to each IDE RAID connector.
- The two connectors support hard disk drives only.
- For more information on ATA133 RAID, please refer to ATA133 RAID 0 or
1 Quick User's Guide.
TIP:
If you install two hard disks on cable, you must configure the
second drive to Slave mode by setting its jumper. Refer to the
hard disk documentation supplied by hard disk vendors for
jumper setting instructions.
