I have an old Dell XPS Gen2 with WD Raptors in RAID0 using WinXP. I want to upgrade to Win7, but there are no RAID controller drivers for Win7 for this machine. So I want to remove the RAID array and replace it with an Intel SSD (only 2 SATA connectors on MB). Questions: do I physically remove the WD drives first? Do I turn off RAID in the RAID controller (^I at startup) or in the BIOS setup (^F12) first? Does it matter?
