Because there are many orders of latency magnitude between spinning rust and tape.
We still use a lot of spinning disk for precisely this reason - you get roughly 5x the online capacity for the same cost and automation does not whine about wanting the new shiny.
- nostrademons 6y agoThat was why I mentioned SSDs - there are orders of latency magnitude between SSDs and spinning disk. I guess it fits the NSA's use-case though, where they have ~thousands of analysts running complex queries but no external users, rather than ~billions of external users running well-defined queries.
