I'm trying to match the appropriate PCIe2 SATA III RAID card to pair of SSDs in RAID 0. I have two PCIe2 slots avail, 4x and 16x. Here's where I'm confused: If the max throughput with 8x is 4Gb/s and SATA III is 6Gb/s, why aren't the cards all 16x? The two-port ones all seem to be 2x. What am I missing? Thx!
