Is there an inexpensive NAS Raid 1 device available? - firewire -raid enclosure multi sata

Hello

I would like to add some network drives to my home network to any computer can store data and also provide backup. I want either a RAID-1 on the base. Can anyone recommend something.

Note that I will not try to use the USB or Firewire RAID device that I sit on the local network and not physically connected to a PC

Thanks

Jonathan
