My work depends on generating, storing and analyzing a large amount of data -- averaging about 1 TB per month. I would like to have a storage system which is automated, fast, reliable and most importantly does not cost the price of an eye. Right now, I have a 4 node Linux cluster with 10 large hard disks (total capacity 1.6 TB); data storage roughly costs about $0.60/GB (excluding the cost of PC hardware). But long term storage is painful -- DVDs cost about $0.10-$0.15/GB but takes too much human time and leaving data on hard disks makes me nervous because of possible failures. RAID is a possibility, but it increases the cost significantly. I was wondering, if Slashdot readers have any recommendations for a cheap automated way to store and retrieve data."
