VIA6421 PCI to SATA PATA RAID Controller Card for Desktop
VIA6421 PCI to SATA & PATA Hard Disk Controller Card
Upgrade your desktop PC's storage capabilities with the VIA6421 PCI to SATA & PATA Dual Channel Adapter Card. Powered by the reliable VIA VT6421 chipset, this internal expansion card adds full SATA and Ultra ATA/133 support to any standard PCI slot — making it the ideal solution for builders, upgraders, and enthusiasts who need more storage connectivity without replacing their entire system.
Key Advantages
- Flexible Connectivity: Supports both Serial ATA (SATA) and Ultra ATA/133/100/66 (PATA/IDE) interfaces, giving you complete freedom over your storage configuration.
- Outstanding Transfer Speeds: Dual-channel SATA delivers transfer rates of up to 150 MB/s per channel, surpassing older IDE interfaces. Ultra DMA-133 provides up to 133 MB/s on the IDE channel.
- RAID Support: Supports RAID 0, RAID 1, and JBOD configurations, allowing you to maximize storage performance, data redundancy, or simply combine drives as a single volume.
- Hot Swap Compatible: Supports hot swapping for connected SATA devices — swap drives without powering down your system.
- Compact & Easy Installation: Simplified cabling with smaller SATA connectors makes installation straightforward, even in compact PC cases.
- Backward Compatible: Compatible with Serial ATA specification 1.0 and PCI Local Bus specification 2.2 for broad system compatibility.
