There are two issues here. The first is that you actually need access to the RAID volume. What is managing your RAID? If it's a RAID volume you set up in Windows, I don't know for sure, but it's highly unlikely that you'll be able to access that partition. If you have a RAID hardware card, then all you need is a linux driver for your H/W RAID card.
The second issue is NTFS access. You can go with a
commercial NTFS driver for Linux, or the
open-source solution.
Your biggest issue is going to be with RAID.
