I'm getting ready to build a new computer. My last setup used two 75gb rapors for RAID 0 and then weekly I created a mirror back up on an esata external drive. I'm not crazy about that setup as it seems to easy for something to go wrong. In any case, on this setup I was thinking about using two 150gb raptor drives and then using a 300gb raptor drive to use as my weekly backup. I use a program called Acronis which makes a copy of the drive of the C drive so that if it ever goes down, I can reboot using the backup drive and it should work perfectly. So does that sound like a decent setup?
