Question
When designing a solution, what is the best use-case for Solid State Disk drives?
Options
- ATo facilitate big sequential writes
- BIn non-mission-critical environments
- CFor backup to disk solutions
- DFor mission-critical server applications, databases, and online storage
Explanation
SSDs deliver extremely low latency and high random I/O throughput, making them best suited for mission-critical workloads like databases and online transaction processing.
Common mistakes.
- A. Big sequential writes (such as streaming or bulk data ingest) are a strength of high-capacity HDDs, which are more cost-effective per GB for large sequential workloads than SSDs.
- B. Non-mission-critical environments do not justify the higher cost per GB of SSDs; HDDs are the cost-efficient choice where performance and reliability are less critical.
- C. Backup-to-disk solutions prioritize high sequential throughput and low cost per GB, making large-capacity HDDs the appropriate and economical choice over SSDs.
