Sigma UltraATA 133 PCI RAID Controller interface cards/adapter

Sigma SC-PR4B12-S4 UltraATA 133 PCI RAID, High-speed dual channel Ultra ATA/133 RAID (0, 1, 0+1) controller for PC. Features

- RAID configurations protect your system from catastrophic disk failures and system down time while doubling the data transfer rates of your hard disk drives
- Regulatory approval(s): FCC Class B (DoC) & CE
- Port type: Two IDE 40-pin connectors
- Slot type: 32-bit PCI
- Supports Ultra DMA (0-6) and Multi-word DMA mode (0-2)
- Achieves burst data transfer rates up to 133MB/sec
- CRC error-checking provides data verification and achieves flawless data transfer
- RAID 0 (striping) interleaves data across multiple hard disk drives, which increases disk system performance dramatically.
- RAID 1 (Mirroring) simultaneously writes data to two hard drives for data redundancy
- RAID 0+1 (Mirroring + Striping) the best of both worlds - combines mirroring + striping - four hard drives required for this mode
- Acts as a conventional (non-RAID) controller when not configured for RAID
- On-board BIOS supports booting from attached hard drive or stripe set
- Support scatter/gather, multi-threaded, multi-tasking and automatic FIFO threshold selection
- Provides two independent Ultra ATA channels (built-in 256-bytes FIFOS per channel) for faster data transfer
