Shared between multiple computers
Network bandwidth and other computers use can be a bottleneck
Lots of reads/writes per second will saturate the network afecting the whole cluster performance
Unique for each computer
Access not influenced by external factors
Lots of reads/writes per second will on only afect itself, not the cluster performance
