The reason I wrote this article was from a customer who wanted to know whether the cost to store a petabyte of storage in the cloud or on premise for 3 years. My first thought was the cloud, and I am only talking about storing the data, the pricing excludes the Egress and Ingress charges that would make cloud storage much more expensive.
What does a Petabyte of Storage Cost? The Cloud
In order for us to compare an on-premise solution vs a cloud solution we need to establish a few criteria. We chose to use Microsoft Azure Blob Storage for both Hot and Cool pricing and purchased a 3-year reserved blob – Flat Namespace – LRS – UK South:
Hot £10,287 per month x 12 x 3 = Total cost £370,332
Cool £5,626 per month x 12 x 3 = Total cost £202,536
The quoted price surprised me as it was considerably more than I had been expecting. I then compared this to a Seagate Exos® CORVAULT™ populated with a total of 106 Exos drives!
Seagate Exos CORVAULT
Exos® CORVAULT™ is a high-performing, efficient, durable multi-petabyte capacity block storage system that is self-healing and brings five-nines availability to scale out storage for data centre deployments. CORVAULT breakthrough technologies provide hyperscale efficiencies, rapid deployment, and automatic hard drive renewal for less e-waste and operational costs.
What does a Petabyte of Storage Cost? On-Premise
Now we get the surprising part, the price for the Seagate Exos CORVAULT with 3 years 24x7 support and maintenance is £50,000 and it fits in 4U!
So how much does it cost to store a petabyte of data on-premise including energy consumption?
2000W x 24 hours x 365 days x 0.35 kW/h x 3 years = £18,396
The total cost is a £68,396 for 3 years!

The Surprise
On-premise storage worked out to be.
540% cheaper than Microsoft Hot Storage
337% cheaper than Microsoft Cool Storage
This comparison really did throw up an unexpected result as unlike the cloud you don’t pay any additional charges data transfer charges.
