"Hardware RAID" can very well include a controller with dedicated parity processing, battery/flash backed write caching and other tangible benefits.
Yes, battery/flash write-back cache provides some performance benefit in write intensive workloads. but all that parity processing? your x86_64 server processor is far faster than the typical few 100Mhz MIPS/ARM sort of CPU they embed on those controllers, and can easily keep up in realtime, and I'd far rather have the OS native volume manager open source managing the physical volumes than some black box firmware.
