As a storage analyst, I am repeatedly asked to compare one storage technology solution to another. Several years ago, this wasn’t very difficult. In enterprise storage, there were really only a couple options: SAN or NAS. When comparing SAN storage, evaluations looked at performance, data resiliency features, and price. When comparing NAS solutions, technical comparisons likely emphasized price and capacity scaling, along with a myriad of different file system-specific features such as how granular the system could manage quotas or snapshots. Depending on how you look at it, those might be considered the good old days for a storage analyst. Comparing solutions was relatively easy.
