🟦 QNAP TL-D800S

🔹 Processor (CPU)

❌ Not applicable

👉 The TL-D800S does NOT have a CPU, because it is a direct-attached storage (DAS) / JBOD expansion unit, not a NAS.

Instead:

• All RAID processing is handled by the connected QNAP NAS or host PC/server
• Works as a pure storage extension layer

📌 Key Point:

• No internal computing
• No apps or OS inside the enclosure

🔹 Memory (RAM)

❌ Not applicable

👉 The TL-D800S has no RAM installed, because:

• It does not run QTS or any operating system
• It depends entirely on the host system for memory management

🔹 Storage (Drive Bays)

• Drive Bays: 8 × 3.5” / 2.5” SATA 6Gb/s
• Hot-swappable: Yes
• Drive Support: HDD & SSD (SATA only)

👉 RAID Behavior:

• RAID is managed by the host NAS or PC
• Supports large capacity expansion pools

🔹 Connectivity (Host Interface)

• Interface: 2 × SFF-8088 Mini-SAS ports
• Connection Type: Direct-attached (DAS / JBOD)
• Controller Required: QXP-800eS PCIe expansion card (included in bundle)

👉 Performance:

• High-speed multi-lane SAS connection
• Significantly faster than USB/eSATA JBOD solutions

🔹 Performance Overview

• High sequential throughput (depends on host system)
• Suitable for:
  • Large backups
  • Archiving
  • Media storage
  • Enterprise data expansion

📌 Example performance (lab conditions):

• Over 3,000 MB/s read/write in RAID 0 SSD setups

🔹 System Role (Important)

👉 TL-D800S is NOT a NAS

It is:

• A storage expansion enclosure
• Used to increase capacity of:
  • QNAP NAS systems
  • Windows servers
  • Linux (Ubuntu) systems

📌 Key limitation:

• Cannot install apps
• Cannot be used independently
• Cannot be merged into NAS system pool directly

🔹 Power & Cooling

• Power Supply: 250W PSU (internal)
• Fans: 2 × 120mm cooling fans
• Operating Temp: 0°C – 40°C
• Noise: Depends on installed drives

• Weight: ~8.1 kg (without drives)
• Build: Metal chassis for enterprise reliability

🔹 Key Highlights

• 8-bay high-capacity storage expansion
• Mini-SAS high-speed connectivity
• Supports HDD & SSD
• Enterprise-grade cooling system
• Works with QNAP NAS & servers
• Massive scalability without replacing NAS

🎯 Best Use Cases

• NAS storage expansion (QNAP enterprise systems)
• Backup & disaster recovery storage
• Media production storage (4K/8K workflows)
• Surveillance recording expansion
• Archiving large datasets

❓ FAQ

1. Does TL-D800S have a processor or RAM?

❌ No. It has no CPU or RAM. All processing is done by the connected NAS or server.

2. Can I use it as a standalone NAS?

❌ No. It is a JBOD expansion unit only.

3. Can I install applications on it?

❌ No. It does not run any operating system.

4. How is it connected to a NAS?

It connects via:

• Mini-SAS (SFF-8088) cables
• Requires QXP expansion card in the host system

5. Can I mix HDD and SSD in the same RAID?

⚠️ Not recommended

• QNAP advises using same disk type in a RAID group

6. Is it faster than USB expansion units?

Yes. Mini-SAS provides much higher bandwidth and stability compared to USB/eSATA.

7. Does it increase NAS storage directly?

Yes, but:

• It creates a separate storage pool
• It is not merged internally into existing RAID arrays

8. Who should use TL-D800S?

👉 Ideal for:

• Enterprises
• Video production studios
• Backup-heavy environments
• IT storage expansion needs
