RAID-5 in 2005 - New Onboard and Add-In Solutions Compared : Article

Quote: The last time we ran a comparison article against RAID-5 solutions, we were starting to see the first inclinations of low-cost RAID-5 solutions hitting the market. The first onboard solutions with RAID-5 connectivity from Silicon Image had starting making their way onto motherboards, bringing the functionality down to an incredibly low price point. While Silicon Image's first motherboard-level RAID-5 solution were certainly inferior to a dedicated RAID-5 card with hardware processing, they got a lot of people thinking about RAID-5 who would have never considered it before. Here we are, six months later, and the RAID-5 landscape is changing dramatically once again. Many high-end motherboards hitting the market not only have RAID-5 connectivity onboard, but they are native solutions. Both nVidia's nForce4 SLI Intel Edition and Intel's own 955/945-series chipsets have the ability to process RAID-5 directly in their Southbridge controllers. Native solutions typically allow for very impressive performance, as they can bypass the PCI/PCI-X/PCIe busses completely and connect directly with the chipset. Of course, we were very curious to see how these solutions compared to the far more expensive add-in board solutions, not only in raw performance, but in terms of features and usability.
