Accurate Benchmarking utilities for various hardware?

[neonerd]

Does anyone know some accurate benchmarking utilities for hardware such as HDD's, CPU's, RAM, etc...i need it to have similar functionality/information as sisoft sandra, but from what i was told sandra was in accurate. I was also told that this article isn't accurate because i used sandra for it. does 56 Megabits/s sound normal for a WD Raptor drive transfer rate?
