I'm using a Dell I got for free as an image server but it only has two SATA ports and I need more. My plan is to run RAID 5 with four 750's so I was going to get an SATA 4-port card and store them in an external incloser. What's a good four port card that works well with software raid? The dell has 2 PCI slots, 1 PCIe x 1 slot, 1 PCIe x 16
