Zettlab NAS model and configuration data
Compare Zettlab NAS models by drive bays, vendor-listed capacity, processor, memory, network ports, ZettOS image series and component warranty.
Drive-bay count and listed capacity stay separate
The D4/D6 product page labels the family diskless and explicitly says hard drives are not included. Its maximum-storage formulas are manufacturer capacity claims, not installed storage in the selected unit.

| Model | SATA drive bays | Maximum storage formula shown by Zettlab |
|---|---|---|
| D4 | 4 | 100TB (24TB × 4 + 4TB × 1) |
| D6 | 6 | 148TB (24TB × 6 + 4TB × 1) |
| D6 Ultra | 6 | 152TB (24TB × 6 + 4TB × 2) |
| D8 Ultra | 8 | 200TB (24TB × 8 + 4TB × 2) |
Standard and Ultra models have distinct hardware profiles
The comparison table differentiates D4/D6 standard models from D6/D8 Ultra models by processor, memory, system drive and network ports. Retain the family boundary because equal bay counts do not imply equal hardware.

| Model family | Processor and memory | Network and internal storage fields |
|---|---|---|
| D4 / D6 | RK3588, 8 cores and 6 TOPS NPU; 16GB LPDDR4x, maximum 16GB. | One 1GbE and one 2.5GbE port; one M.2 slot; 32GB eMMC system drive. |
| D6 Ultra / D8 Ultra | Intel Core Ultra 5 125H, 14 cores / 18 threads / 34 TOPS; 32GB DDR5, maximum 96GB. | Two 10GbE ports; two PCIe 4.0 x4 M.2 slots; 256GB SSD system drive; SFF-8654 PCIe 4.0 x8 expansion. |
ZettOS downloads and warranty follow the model and component
Zettlab labels separate ZettOS system-image downloads for standard and Ultra device families. Its warranty page also separates the NAS unit and included power parts from third-party drives and memory.

| Support field | Published scope | Data handling |
|---|---|---|
| ZettOS image series | Standard Series is labeled for D4/D6; Ultra Series is labeled for D6 Ultra/D8 Ultra. | Keep the system-image family tied to the exact model; do not mix it with general app downloads. |
| NAS and included parts | The limited warranty lists two years for the NAS main unit and one year for the included original power adapter and cables. | Record component and purchase source alongside the stated coverage period. |
| Third-party drives and RAM | The warranty says hard drives and memory are governed by their respective manufacturers' warranty policies, not Zettlab's limited warranty. | Keep installed component model and component-maker warranty separate from the NAS chassis record. |
