## 🌟 Overview

The WIA-COMP-002 standard defines the framework for next-generation data storage systems, including DNA storage, holographic storage, quantum storage, phase-change memory, and ultra-high-capacity storage architectures.

**홍익인간 (弘益人間) - Benefit All Humanity** - This standard aims to preserve humanity's knowledge for millennia, enable sustainable data archival, and provide unprecedented storage densities for the data explosion era.

## 🎯 Key Features

- **DNA Storage**: Synthetic DNA for petabyte/gram density
- **Holographic Storage**: 3D optical data recording
- **Quantum Storage**: Quantum state-based information storage
- **Phase-Change Memory**: Ultra-fast non-volatile memory
- **Persistent Memory**: NVDIMM and Intel Optane technology
- **Computational Storage**: In-storage processing
- **Tiered Storage**: Hot/warm/cold data management
- **Data Reduction**: Compression, deduplication, erasure coding
- **Energy Efficiency**: <0.1W per TB stored
- **Data Longevity**: 1000+ year retention

## 📊 Core Concepts

### 1. Storage Tiers

```
Storage Hierarchy:
- Ultra-Hot: Persistent Memory (PM) - <1μs latency, $/GB high
- Hot: NVMe SSD - 10-100μs latency, $/GB medium
- Warm: HDD - 5-10ms latency, $/GB low
- Cold: Tape/Optical - seconds latency, $/GB very low
- Archive: DNA/Holographic - minutes-hours, $/GB ultra-low
```

### 2. Performance Metrics

| Technology | Density | Speed | Latency | Retention | Cost/TB |
|------------|---------|-------|---------|-----------|---------|
| DNA Storage | 1 EB/gram | 1 MB/s | Hours | 1000+ yr | $1K |
| Holographic | 1 TB/disc | 1 GB/s | 100 ms | 50 yr | $10 |
| PM (Optane) | 512 GB | 10 GB/s | 100 ns | 10 yr | $500 |
| NVMe SSD | 30 TB | 7 GB/s | 10 μs | 5 yr | $50 |
| HDD | 20 TB | 300 MB/s | 5 ms | 5 yr | $15 |

## 🔧 Components

### TypeScript SDK

```typescript
import {
  calculateStorageDensity,
  optimizeTiering,
  encodeDNA,
  simulateHolographic,
  estimateRetention
} from '@wia/comp-002';

// Calculate DNA storage capacity
const dnaStorage = calculateStorageDensity({
  technology: 'DNA',
  mass: 1, // gram
  encoding: 'base4',
  errorCorrection: 'reed-solomon'
});

console.log(`Capacity: ${dnaStorage.capacity} bytes`);
console.log(`Density: ${dnaStorage.density} bytes/gram`);
```

### CLI Tool

```bash
# Calculate storage density
wia-comp-002 calc-density --tech DNA --mass 1

# Optimize tiering policy
wia-comp-002 optimize-tiering --total-data 100TB

# Encode data to DNA
wia-comp-002 encode-dna --input data.bin --output dna.seq

# Simulate holographic storage
wia-comp-002 simulate-holographic --layers 100
```

## 🚀 Quick Start

### Installation

```bash
cd wia-standards/standards/next-gen-data-storage
./install.sh
wia-comp-002 --version
```

### TypeScript Usage

```typescript
import { NextGenStorageSDK } from '@wia/comp-002';

const sdk = new NextGenStorageSDK();

// Optimize data tiering
const tiering = sdk.optimizeTiering({
  totalData: 100e12, // 100 TB
  accessPattern: {
    hot: 0.1,    // 10% frequently accessed
    warm: 0.2,   // 20% occasionally accessed
    cold: 0.7    // 70% rarely accessed
  },
  budget: 5000 // dollars
});

console.log(`Cost: $${tiering.totalCost}`);
console.log(`Performance: ${tiering.avgLatency} ms`);
```
