+# RAID Module Development Progress
+
+## Date: 2026-05-17
+## Status: Phase 1 (30% Complete)
+
+## Completed
+
+### Core Module Structure
+- ✅ `src/raid/mod.rs` - Core interface and enums
+- ✅ `src/raid/controller.rs` - RAID controller and array management
+- ✅ `src/raid/level_0.rs` - RAID 0 Stripe algorithm
+- ✅ `src/raid/level_1.rs` - RAID 1 Mirror algorithm
+- ✅ `src/raid/level_5.rs` - RAID 5 placeholder (stub)
+
+### Implemented Features
+- ✅ RaidLevel enum (0/1/5/6/10/50/60)
+- ✅ MemberStatus enum (Online/Offline/Rebuilding/Failed)
+- ✅ RaidAlgorithm trait (read/write interface)
+- ✅ RaidController (create_array/read/write)
+- ✅ RAID 0 Stripe: locate_block algorithm
+- ✅ RAID 1 Mirror: read from first member, write to all
+
+### Test Infrastructure
+- ✅ Test program: `src/bin/raid_test.rs`
+- ✅ Test disks: 3 × 5GB sparseimage
+- ✅ Compilation successful
+
+## Pending
+
+### Week 2: RAID 5/6
+- ❌ XOR Parity calculation (parity.rs)
+- ❌ RAID 5 rotating parity position
+- ❌ RAID 5 reconstruction
+- ❌ Reed-Solomon library (RAID 6)
+- ❌ RAID 6 double parity
+
+### Week 3: Nested RAID
+- ❌ RAID 10 (Mirror + Stripe)
+- ❌ RAID 50 (RAID 5 + Stripe)
+- ❌ RAID 60 (RAID 6 + Stripe)
+
+### Week 4: Integration
+- ❌ WebDAV handler integration
+- ❌ Single RAID device export
+- ❌ Performance testing (AJA)
+- ❌ Fault simulation
+
+## Architecture
+
+```
+RaidController
+├── RaidArray {level, members, stripe_size}
+└── RaidAlgorithm trait
+    ├── Raid0.read/write (Stripe)
+    ├── Raid1.read/write (Mirror)
+    ├── Raid5.read/write (Parity)
+    ├── Raid6.read/write (Double Parity)
+    └── Nested RAID implementations
+```
+
+## Performance Target
+
+- RAID 0: >=600 MB/s (3盘叠加)
+- RAID 5: >=500 MB/s (校验开销)
+- RAID 6: >=400 MB/s (双校验开销)
+
+## Next Steps
+
+1. Implement parity.rs (XOR calculation)
+2. Complete RAID 5 read/write logic
+3. Add Reed-Solomon library for RAID 6
+4. Test fault recovery
+
