Re: [PLUG] Real (driverless) hardware RAID controller for PC?

You need no special hardware to use RAID with mdadm.

This is very helpful.  I have two more questions:

1. There are many motherboards that advertise themselves as offering onboard RAID.  My understanding is that these are essentially a built-in "fake raid" controller, in that they still offload work to the OS and therefore require a driver.  Is that correct?

2. Looking at the linux RAID wiki on kernel.org, it seems that no special hardware is required to set up and use RAID with mdadm--a couple of hard drives plugged into the onboard SATA controllers of any ol' motherboard would be fine.  Is that also correct?
