RAID 1 or 5?

[chez]

I have just added a further 2x500gb drives to my system for storage, in addition to the existing 2x500gb drives.

The current drives are configured in RAID1 for redundancy. Now that I have 4 identical drives, would I be better off configuring all 4 as a RAID5 array?

Any thoughts/opinions welcomed

Thanks

Hmm.. I think I may just go with 2x RAID1 arrays then.. Storage is cheap enough that if I need more, I can always throw more drives at it..

Thanks for the advice
