Where I work, we pay over $8K per 1TB per year..... this is why.Since the introduction of x86 based servers at the end of the 20th century, the cost of server hardware has declined rapidly while the performance per watt and performance per dollar has increased rapidly. This pushed the server market to evolve from closed, proprietary, and most importantly extremely expensive mainframe and proprietary RISC servers into today's highly competitive x86 server market. Howerver, the professional storage market is still ruled by the proprietary, legacy systems.
Today, you can get a very powerful server that can cope with most server workloads for something like $5000. Even better, you can run tens of workloads in parallel by virtualizing them. But go to the storage market with four or even five times the budget and you will likely return with a low end SAN.
