I am looking for an eSATA/USB2 external box capable to accomodate 3-5 3.5" sataII disks, RAID5 capable, Hot-swappable.
What would you guys recommend? I do not need a network interface, nor I need NAS features. I am just looking to expand a server with external storage for backup reasons. I'd like something simple (and inexpensive?) and reliable.

So far I only found a LaCie 4Big Quadra.
