The Fully Burdened cost of storage is an all-consuming topic especially important for business owners trying to get clarity on the Total Cost of Ownership for storage. Here is a link to a slide that articulates the industry average fully burdened IT infrastructure cost percentages to support data growth. Categories include disk storage with tape, software costs, infrastructure costs such as telecom, power, floor and staffing costs.
I also wanted to share a comment about the carbon footprint of a GB. Ever thought about that ? I am sure all of us are so focused on being green (or is blue the new green!) that we have at some point in time thought about this. Here is a snapshot of a comment from Matt (Source http://www.vertatique.com/?q=storage-costs-average-25gbmonth#comment-1993)
dcarli asks, "What's the carbon footprint per megabyte stored per month?"
GB is the new MB, so let's look at those.
I have a .5TB NAS device on the office network, rated at 5.6W. I ran the numbers and got ~11 grams of carbon per GB per month, with an electricity cost of 1/10 of a cent.
Of course, I don't know how representative my storage is of the global storage energy profile and a detailed analysis is more complicated.
Our device has a automatic sleep mode, rated at 0.6W. The drive is probably asleep or completely off 12 hours/day, which would cut the footprint almost in half. On the upside, I'm not counting the carbon footprint of the backups, which in a data center might happen at least once a day. Or the data center AC. Or redundant storage, if required. Or the carbon footprint involved in the manufacture and ultimate disposal of the device, backup media, etc.
11 grams does not sound like much; its all those GBs in the aggregate that generates a lot of carbon. This is the materiality problem, which we saw clearly in the motivational analysis for digital delivery.
According to IDC, the amount of data created and replicated globally in 2008 was 486 exabytes (486 billion GB). At 11 grams per GB per month, that is a monthly storage footprint of ~5 million metric tons of carbon, or ~60 million tons/year. ICT is said to account for ~600 million metric tons, which would put storage at ~10%. These are all rough estimates, but give us an order-of-magnitude perspective. **
