When you mean Shared Storage, is it a SAN? With a SAN we can have the maximum performance and High Availability related to storage, but its price is very high, and many times (depending on the solution) it is not a cost-effective solution.

On another hand, there are some scenarios where a centralized storage is not sized correctly, the organizations rely on them for the critical and heavy applications and then they have a poor experience because of the bad design (processes bottleneck in the SAN, shared disks between LUNs, etc).

What matters the most, are the I/O requirements given by the application, with that information you can compare and design what is the best solution for your environment. Unless there is a special regulation in the organization, i.e. Some companies require to store all critical data in a SAN as a compliance rule.

For a request like this you need to give us more info, like size, some idea of the I/o rate, your RPO/RTO, applications involved etc etc
More info is better than less.

Spinning Rust might be the way to go but SSD's might also

Has the OP gone away to find the information and then discovered they can solve the problem themselves now they know all that info?
