Which flash deployment is ideal for environments that need extreme database performance?

A.
Traditional storage

B.
Hybrid array

C.
Server cache

D.
All-flash array

Explanation:
The major benefit of an all-flash array is the ability to deliver sustained levels of extreme performance at a lower price point than that of a storage system that
employs spinning disk drives. For the most part, this means dramatic improvements in response-time performance (latency), or the time it takes to respond to each
and every transaction processed in a database-driven application. For many applications, it is simply unacceptable to have any perceptible variance in transaction
time that could impact the customer experience. In the financial industry, for example, stringent response-time requirements may be the subject of government
regulation.
Another use case for an all-flash array is when you need extreme data throughput (as measured in IOPS) but don’t have a corresponding need for massive capacity
to permanently house all of the incoming data. An all-flash array is the right approach in this type of environment.
