Since high CPU consumption is unusual, I would suspect a device driver issue. Perhaps there is an interrupt conflict such that two devices are using the same interrupt.
On my own system (12 disks), I can run a throughput benchmark and the system remains completely usable as an interactive desktop system, without any large use of CPU or high load factor. The bandwidth bottleneck in my case is the PCIe (4 lane) fiber channel card and its duplex connection to the storage array.
