The Adaptec SCSI Card 39320A-R is a 64-bit 133 MHz PCI-X, dual-channel Ultra320 SCSI card with integrated HostRAID. The Adaptec 39320A-R is a cost-effective RAID 0, 1 and 10 solution. In addition, the Adaptec 39320A-R offers new drivers for HostRAID, both Linux and Windows Server 2003, as well as the same browser-based management tool used by Adaptec RAID products. The Adaptec 39320A-R provides data protection at the fastest SCSI speeds available up to 640 MByte/sec, ideal for mainline storage, streaming video and audio, and other bandwidth-intensive applications. The Adaptec SCSI Card 39320A-R is designed for maximum configuration flexibility and ease of use. Ultra320 SCSI technology is compatible with Ultra160, Ultra2, Ultra Wide and all other previous-generation SCSI devices. The card's PCI-X interface enables host bus rates of over 1 GigaByte per second, making it possible to take full advantage of Ultra320 SCSI's doubled bandwidth. It is also backward compatible.
