I have a single 250GB SATA2 hard drive which I would like to upgrade to a 1TB hard drive. However, I have 2 1TB SATA2 hard drives and a RAID controller which I want to do a mirror RAID on. I figured out how to install them and set up the RAID, but I was curious if anyone has any suggestions on what I should use to mirror my current hard drive onto the 1TB hard drives. There are several options out there I've noticed, but I'm just looking for some advice from those who may have done something like this in the past.

Thanks!
