The MegaRAID IDE RAID Controller is a PCI short Adapter card that provides two IDE channels with Ultra ATA/66 (MegaRAID IDE) and Ultra ATA/100 (MegaRAID IDE 100) capability. MegaRAID IDE provides a simple and cost effective way to improve the performance and reliability of your storage subsystems. MegaRAID IDE offers high transfer rates, and fault-tolerant data redundancy during high performance applications by using low cost Ultra ATA drives in desktops, workstations, or low-end servers. You can connect from one to four drives to this card using IDE cables (Ultra ATA drives need special IDE cables) and configure these drives using a simple setup menu embedded in the MegaRAID IDE BIOS. The card supports the following drive modes: PIO 0-4, DMA 0-2, and Ultra DMA 0-5. In addition, it supports RAID levels 0, 1 and 10. You can use striping (RAID 0) to improve performance or mirroring (RAID 1) to improve data security. RAID 10 provides both RAID 1 (disk mirroring) and RAID 0 (data striping).
