Why throw away your old PC just because you need a new drive and cannot find a good PATA IDE drive for it? Add four independent SATA-I ports to your PCI equipped computer and enjoy the benefits of the optional software RAID configuration for added speed and/or data security with this adapter card from Monoprice!With SATA being the standard for the past few years, it is getting harder and harder to find a good PATA IDE drive for older computers. However, as long as you have an open PCI slot, you can add this adapter card, which gives you four SATA-I (1.5 Gbps) ports, so you can use the newer drives.The card comes with an optional RAID utility, which lets you configure a RAID 0, RAID 1, or RAID 0+1 setup on two or more of the SATA ports. You can have one RAID 0 or 1 setup and two independent SATA drives, two RAID 0 or 1 sets, or a single RAID 0+1 set. The card uses the SIL3114 chipset and will work in a 32-bit 66 MHz PCI bus.It includes drivers for Windows 98SE / ME / NT4 / XP / Server2003 / Vista / Server2008 / 7 (both 32 and 64-bit where applicable) and for various versions of RedHat, Fedora, and SuSE Linux systems.
