Example 3 — Web & Content Delivery
- Role: Serve static web assets and media content
- Benefit: Low read latency and high sequential read speeds improve user experience
Comparison & Fitment Guidance
Read-Intensive vs Mixed-Use SSDs
- Read-Intensive (this model): Optimized for read throughput and lower cost per GB; suited for cache and content-serving roles.
- Mixed-Use / Write-Optimized: Higher DWPD ratings for heavy write workloads (databases with frequent updates, logging); choose those when sustained write endurance is critical.
Callouts for IT Buyers
- Excellent price/performance for read-dominant tiers and cache layers.
- Plug-and-play replacement in validated Dell PowerEdge servers reduces migration friction.
- Backed by Dell’s enterprise support and proven supply chain for spares and warranty service.
