I am currently using a Seagate 250GB hard drive as my system drive. Is it possible to use ATI to migrate to a WD Raptor 74GB hard drive? I am only using 20GB on my system drive, but I'm not sure the best way / product to use. Any suggestions? Also, I am currently running a RAID 1 but would likely disable that before cloning and I'm not planning on using RAID 1 in the future - just a daily backup / image, probably. Any thoughts on that, too? Thanks.
