Re: RAID array for home

I'm thinking why can't there be an hardware adapter which we would plug the
motherboard SATA cable into, the other side would plug into 2 or more Hard
drives.
This would look to the main computer & O/S like a single fast drive.

There are such things. They're usually referred to as RAID chassis or
similar. Have a look at some of the offerings on www.span.com. Not
cheap, but you get what you pay for.

For example, at work I run three 4TB array chassis with 16 300GB SCSI
drives in each. The external presentation is SCSI and the host machine
simply sees the array as a single f*-off big disk.

All the RAID logic is handled by firmware and software in the array
controller and the thing can be managed via variety of methods - a web
browser, a custom Java application, telnet, ssh, etc.
