Re: Re: [gentoo-user] [OT] 3ware SATA Raid

Most hot swap stuff has the drives in caddys that fit in a mount.  The mount contains power connections and drive connections.  the caddy has cables for the disk data and power that go to a connector on the caddy. The caddy slides into the mount and the connections are made.  Some caddies have a lock on the front that cuts off power when unlocked for removal.
