Not every database benefits from flash storage – knowing when it matters requires understanding how much I/O your workload generates, how random it is and how much latency is already costing you.
Does My Database Need Flash?

Understanding I/O: Random vs Sequential
Disk I/O forces a choice between random and sequential access – and that choice defines whether latency compounds or disappears. Flash makes the distinction irrelevant.
The Fundamental Characteristics of Storage
Latency, IOPS and bandwidth are the three properties that define any storage system – understanding how they relate to each other is the first step to knowing what your database actually needs.
Performance: It’s All About Balance…
Database performance problems are rarely solved by faster CPUs alone – the real issue is imbalance between resources, and disk latency is the silent bottleneck that flash storage changes.
New Blog Series: Storage For DBAs
DBAs and storage people speak different languages – this series bridges the divide, translating storage concepts into terms that make sense from a database perspective.
