PCI 4 port SATA RAID INDEPENDENT isolated discs or RAID 0, RAID 1, RAID 0 + 1 (Personal Computers)
I do not include the negative comment, I own several cards controller chipset-based "Silicon Image", I settled on a Win2k8 R2 with 4 WD 1TB disks without any problem. This card has a very good ratio Quality / Price
