Definition:
High Performance Storage refers to storage systems designed to deliver extremely fast data access, high throughput, and low latency for demanding workloads. These systems optimize for speed, concurrent operations, and sustained performance rather than just capacity.
Key characteristics:
- High IOPS (Input/Output Operations Per Second) - handles many read/write requests simultaneously
- Low latency - minimal delay between request and response (microseconds to milliseconds)
- High throughput - moves large amounts of data quickly (GB/s or TB/s)
- Parallel processing - multiple operations occur simultaneously
Technology Types Technology Speed Use Case Cost
| Technology | Speed | Use Case | Cost |
|---|---|---|---|
| NVMe SSD | Extremely fast | Databases, real-time analytics | High |
| SAS SSD | Very fast | Enterprise applications | Medium-High |
| RAM/Memory | Fastest | Caching, in-memory databases | Very High |
| HDD (RAID) | Moderate | General storage | Low-Medium |
| Parallel File Systems | Very fast | HPC, big data | High |
Example:
Video Streaming Platform
The Problem
You need to serve 4K video to 100 million concurrent users with:
Zero buffering
Instant start times (<2 seconds)
Seamless quality switching
Storage Strategy
┌─────────────────────────────────────────────────┐
│ High Performance Storage Layers │
└─────────────────────────────────────────────────┘
Layer 1: EDGE CACHE (Closest to Users)
├─ Technology: NVMe SSD Arrays
