Key benefits Four independent SATA channels: control up to four drives with dedicated SATA buses, allowing flexible storage expansion and configuration on a single card. RAID versatility: supports RAID0 (striping), RAID1 (mirroring), RAID5 (parity), RAID01 (mirroring striping), and concatenation modes to balance performance and data protection. Reliable, costeffective storage expansion: designed to deliver performance and reliable operation at a low cost for storageintensive applications. NonRAID performance: when not configured as a RAID set, each HDD operates normally with SATA speeds up to 150 MB/sec. PCI compatibility: SiI3114 SATA controller chip complies with PCI specification revision 2.3, 32bit, 33/66 MHz, and Serial ATA 1.0 specification. Technical specifications Controller: SiI3114 SATA controller chip Interface type: PCI (32bit) PCI specification: Revision 2.3, 33/66 MHz SATA compliance: Serial ATA 1.0 Channels: four independent SATA channels Drive support: up to four SATA drives RAID levels: RAID0, RAID1, RAID5, RAID01, and concatenation modes NonRAID performance: SATA up to 150 MB/sec per drive RAID and operation details Four independent channels each with its own SATA bus and support for one SATA device per channel RAID configurations provide options for performance (RAID0), redundancy (RAID1), parity protection (RAID5), or combined approaches (RAID01 and concatenation) In nonRAID mode, drives operate as standard SATA devices at speeds up to 150 MB/sec Use scenarios Desktop or workstation storage expansion: add four SATA drives to increase capacity and enable different RAID configurations for performance or redundancy. Small business file server: implement RAID0 for speed, RAID1 for data protection, or RAID5 for a balance of performance and fault tolerance across multiple drives. Media editing and large project storage: use concatenation or RAID01 to maximize throughput for large video or dataintensive workflows while maintaining options for redundancy. Compatibility and notes Compatible with PCIbased systems supporting PCI Rev 2.3, 32bit, 33/66 MHz buses Uses the SiI3114 SATA controller chip and complies with Serial ATA 1.0 specification Provides four independent channels suitable for expanding storage capacity and configuring multiple RAID/concatenation options while preserving normal SATA operation when not in a RAID set
