The VIA VT6421A controller card adds Redundant Array of Independent Disks (RAID) support to desktop computers with an available PCI slot. It lets you install multiple IDE or SATA hard drives to increase performance or back up your data.
Function
VIA's VT6421A controller card supports up to three Serial ATA drives and one IDE drive. It lets you run two Serial ATA drives in RAID mode. You can use RAID striping to combine two hard drives into one virtual drive for faster transfer rates, or RAID mirror to synchronize two drives in case of data loss or hardware failure.
Features
The VIA VT6421 controller card supports transfer rates up to 150 mbps when used with SATA drives and 133 mbps with an IDE drive. It also provides an external Serial ATA interface for connecting external SATA hard drives, DVD or Blu-Ray recorders.
Considerations
Use RAID striping with the VIA VT6421 card if you have another back-up solution and want better performance in games, video editing programs and other disk-intensive software. Use the card's RAID mirroring feature if you need an efficient method for backing up your data.
