** VIA VT6421A Serial ATA RAID PCI Controller Card **

Add additional devices to any computer with this RAID
controller card. It features the VIA VT6421A chipset, compliant with Serial ATA Specification Rev 1.1, supports external flash for BIOS expansion and RAID functions. This PCI card has two Serial ATA connectors (two internal connectors) with data transfer rates of up to 150 MB/second and one internal
UDMA/133 IDE connector!

For XBOX 360 users, this card is the VT6421A (6421A) chipset. The only difference between the VT6421A and VT6421L is that the VT6421A requires MTKFlash (flash) to hexedit the port I/O's. If you use Xtreme Boot Maker, XBM will do this for you automatically.

For those of you looking for a VIA based SATA card that is not expensive, works and is available worldwide I have just tested and installed it. Let Windows search the CD for drivers and use xtreme boot maker to create a bootable usb stick.

    What is the difference between the VT6421A and VT6421L chipset? The VT6421L card can flash the Samsung drive and "bad-flash" an MS28 without soldering.

    If you want the VT6421L chipset instead, we sell the VT6421L chipset PCI card separetely.

    The VT6421L has been out of production since Dec 2006. If you find a retailer selling a "VT6421L" please verify as it is most likely VT6421A chipset.
