So in the past we have had discussions about LaCie drives. Despite some fellow members warning about their drives, I bought one. The drive enclosure is sold as "hot swappable". However, they won't sell you the drive trays alone. So when you fill up your RAID you have to buy overpriced drives from them. In fact, removing the old drives from the trays voids their warranty. I don't think this is normal, as I am always free to buy whatever hard drives I want with other hot swappable systems. If I am wrong, let me know. Otherwise, I stand by not recommending LaCie to anyone.
