I'm curious what Windows would do with the following setup. Keep in mind that I will be using software RAID. My Windows drive is a 120GB SATA drive. I will partition this drive into two letters, C (40GB) and D (80 GB). I will install two more drives, both 80GB IDE drives (WD800JB). I would like to create a software RAID array with both IDE drives and the D partition. Do you think this would even work, and if so, would the array run faster just with the two IDE drives?
