Why is Cloud Storage More Expensive than External Hard Disks?

Cloud Storage More Expensive

Microsoft Azure’s Blob Cloud Storage price varies somewhere between INR 1.01 and INR 3.31 per Gigabyte per month. So if you extrapolate, 10 Terabytes would cost between INR 10,340 and INR 33,890 per month. By contrast, an external hard drive of 1-Terabyte capacity would cost around INR 3,800 to buy on

So 10 TB of hard drives would probably cost: INR 38,000 one time.

So, why is Cloud Storage so Expensive?

In order to provide 1 TB of storage in a production grade environment, you would have to make the below expenses, at a minimum. This assumes you already have a secure building with a room for storing your servers:

(Total Monthly Average for Up Front purchases is calculated assuming a 5 year use period).


So, we can see that the price per GB to have the most basic setup for a production ready environment that stores 10 TB data, will cost at least INR 16.08 per GB per month. It would cost much more if you don’t already have a safe room where you can house your servers More cost is added when an application like a Document Management System is running, which needs more space for storing incremental backups, search indexes and system files.

This is almost 16 times as expensive as Cloud Storage!

Simply comparing the cost of an external hard drive to the cost of cloud storage is not correct. One must compare the cost of managing that hard drive in a production grade data centre, with the cost of cloud storage.
