Absolutely. In-core on a neighboring machine can be accessed in less than 1ms. On-disk on the local machine (or any machine) can take tens of seconds.

Surely you meant 10's of milliseconds. But even so, fastest SSD random access latencies are in sub-millisecond ranges.

No I did not mean that. Contended local disk access under heavy random read/write workloads takes essentially forever.
