You don't need an additional controller necessarily, because you can set up a RAID 1 with two single ATA hard disks. You'll find a small how-to at [1]. Even most cheap ATA chipsets have hot-swap capabilities. [1] http://people.freebsd.org/~rse/mirror/ I have good experiences with SATA PCI controllers from Highpoint. Björn
