Promise FastTrak SX Storage controller

The FastTrak SX4060 ATA RAID PCI adapter delivers industry leading RAID 5 performance at an unprecedented performance-to-price ratio. For companies running popular applications like web services, file/email servers, audio/video streaming and near line storage, the FastTrak SX4060 opens the world of professional RAID 5 performance and data protection and combines it with cost-effective Ultra ATA (PATA) drives for the ultimate internal storage solution. Based on OEM-proven RAID 5 technology, the FastTrak SX4060 competes with SCSI RAID 5 controllers-at one half to one-third of the price. RAID 5 storage protection is no longer the privilege of budget-rich IT departments. RAID 5 implementation involves striping data and parity information (XOR) across the storage array. Since those parity calculations are so processor-intensive, RAID 5 controllers traditionally require a dedicated CPU to perform the XOR calculations and manage the array.
