RAID5 will give you more space at the expense of performance and at a slightly increased risk of failure (google "raid 5 write hole") - I have a similar system to you - except I have 6 500GB drives in three raid 1 pairs which are then striped to make a 1.5TB volume. RAID5 rebuild takes a *long* time on most systems and will significantly impact system performance if you do it on a live box. RAID 1 rebuild should be a bit faster as all that has to happen is a disk copy. If you really have the time try both and "fail" a drive in both configs (pull the power works well :-) and see what you have to do to bring it back on line - go with the one you are most comfortable with. In the end it's probably a religious decision (strongly held views not always supported by facts).
