Tell me how your software RAID stands up to hundreds of concurrent users connecting to an IMAP service like cyrus with Horde webmail. Had a system like that years ago with good SCSI drives which had performance issues. Switched the system to new server with hardware RAID controller, performance was excellent. I think it's partially the better latency performance you get with dedicated RAID disk controllers.
If we are going back a few years, I had a system with a real hardware RAID card and enterprise drives, yet performance was horrible. The RAID card vendor agreed that the configuration should work well, but ultimately blamed the performance issues on the type of workload.
So, in my experience, dedicated RAID disk controllers do not guarantee good performance.
