- Overall write performance is 25% to 90% better than single spindle performance and 1.5 to 6 times better than other array levels
- Host interfaces are scalable for connectivity or increased host transfer bandwidth
- Small reads in multi user environment have very high cache hit rate resulting in near zero access times
- Write performance improves with an increase in the number of drives in the array
- Access times decrease with each increase in the number of actuators in the array
- No extra data transfers required for parity manipulation
|
- One vendor proprietary solution
- Extremely high cost per MB
- Very short warranty
- Not user serviceable
- Power supply must be UPS to prevent loss of cache data
