1. Can they assure an exact usable capacity figure?
2. Can they assure consistent performance levels with mixed workloads?
3. What happens if they don't meet the promised 99.999% availability?
4. Can storage needs be scaled whenever needed without a forklift upgrade or data migration?
5. Can maintenance renewal costs be assured after the pre-paid term is up indefinitely?
6. What happens if an SSD wears out after the warranty expires?
