- Actual Registers, cache, DRAM, Disk, tape, CD, Flash & EPROM
- Registers - fast, local, volatile, VERY expensive, very small
- cache - fast, expensive, volatile, small
- DRAM - medium size & speed, volatile
- Disk - slow, low cost per byte, von-volatile
- tape - very slow, very low cost, durable, von-volatile
- CD - slow, "read only", good data density, von-volatile
- Flash & EPROM - small, not as fast a DRAM, von-volatile
