The Escalade 9000 series is faster for RAID-5 - The 9500S adds SDRAM (Synchronous DRAM) for buffering. - The 9550SX adds an IBM PowerPC 400 series embedded microcontroller with SDRAM. For RAID-0, 1 or 10, they _all_ use (the 7000 series forward) the same ASIC with SRAM (Static RAM) for 0 wait state, non-blocking operations. So if you want the ultimate in read _and_ write performance, RAID-10 is typically the way to go. -- Bryan NOTE: Areca's Intel X-Scale power ARC-11x0 (PCI-X) and ARC-12x0 (PCIe) series are getting rave reviews for their RAID-5 and RAID-6 performance. The 400+MHz X-Scale (superscalar ARM) seem to be able to handle data transfer rates (DTRs) in excess of what the 3Ware ASIC (9500S) or IBM PowerPC 40x (9550SX) seem to be able to handle. However, Areca is newer and doesn't have the same track record on Linux or always work "out-of-the-box" -- although many people like them so far (including myself). -- Bryan J.
