What are the cheapest Hardware RAID Controllers for IDE and SATA, respectively?
Cheapest I can find is $87 for the SATA HighPoint controller, I forget the model # at the moment, but it was featured on THG (dare I say )
Why do you want hardware *and* cheap? I don't think you're going to get hardware raid for under $100 - the Highpoint is partially (at least) software raid, for example. The cheapest SATA card I'd trust to be fully hardware-accelerated would be the LSI Megaraid, at $240; the PATA equivalent is the 3ware 7506, which is so outdated I'm *very* surprised to hear Newegg carries it anymore. Pretty much the only hardware card I'd recommend these days is the Areca series; they're more expensive but from what I can tell it's worth it.
