*You have a point there. While the company is somewhat small (much of what we do works with uncompressed video files or images, hence the space usage) and so the risk of loosing a ton of money is also small, the fact remains that the point of setting this up was to avoid the need to restore the backup in the first place. I do like the hot spares though. I forgot about those. I'll think about it before making the final choice. But this is good points made, thank you.*
