datawebotTerraMaster storage data: NAS, DAS and drive compatibility
Compare TerraMaster storage by NAS or DAS role, bays and interfaces, RAID behavior, capacity basis, model-specific drive support and included accessories.

NAS hardware and capacity depend on model configuration
TerraMaster product pages report bay count, memory, network ports, RAID choices and raw capacity at the model level. A short category card and a detailed specification can report different configurations, so retain the page and selected model with each value.

| Product detail | F4-424 Max example reviewed 8 October 2026 | What the figures mean |
|---|---|---|
| Memory and selected configuration | The Home/SOHO NAS category card describes the F4-424 Max as 16 GB RAM. Its detailed specification lists one pre-installed 8 GB DDR5 module, two memory slots and up to 64 GB supported. | Keep the category card and detailed product-spec source attached to the value. The reviewed pages do not resolve whether the difference represents a selectable configuration. |
| Raw capacity and array choices | The detailed F4-424 Max specification lists four drive slots, 88 TB maximum internal raw capacity (22 TB × 4), and TRAID, TRAID Plus, Single, JBOD, RAID 0/1/5/6/10. | The page says raw capacity may change with drive releases and that maximum single-volume size is not directly related to maximum raw capacity. Do not report raw capacity as available volume space. |
| Interfaces and expansion | The F4-424 Max specification lists two 10GbE ports and two M.2 2280 NVMe slots, alongside four SATA drive bays. | Keep network throughput ports, internal storage bays and NVMe cache slots as separate hardware fields. |
D6-320 is a USB enclosure with a host-dependent storage role
A multi-bay DAS enclosure and a NAS do not expose the same storage behavior. The D6-320 page is particularly useful because it describes both standalone disk operation and expansion through a compatible TerraMaster NAS.

| D6-320 distinction | Current product-page evidence | Comparison boundary |
|---|---|---|
| Host and drive interface | D6-320 is a six-slot enclosure for 3.5-inch SATA HDDs, 2.5-inch SATA HDDs or 2.5-inch SATA SSDs. It uses USB 3.2 Gen 2 Type-C at 10 Gbps and lists Windows, macOS and Linux support. | Record it as USB DAS; six bays do not make it a network-attached NAS. |
| RAID and raw-capacity wording | The product description gives a theoretical 192 TB total from six 32 TB drives but says the enclosure runs in standalone-disk mode and does not support RAID arrays. Its detailed spec lists `SINGLE DISK`, no hardware RAID or RAID manager, and a capacity note that says the total varies with RAID type. | The page’s capacity and RAID wording is internally inconsistent. Keep 192 TB labeled as its stated theoretical maximum; do not present it as a built-in RAID array or usable capacity. |
| NAS expansion and package contents | The product page says a compatible TerraMaster NAS using TOS 5.1 or later can use D6-320 to expand storage pools. Its package-contents list names the enclosure, power items, USB cables, screws and guide; it does not name drives. | Separate host-created storage pools from the enclosure’s own RAID specification, and do not count drives as included when they are absent from the listed package contents. |
Drive compatibility is a model-to-model relation
TerraMaster’s HDD compatibility table identifies drive models and their supported NAS models. A compatibility label answers whether TerraMaster lists a drive for a model; it does not replace that NAS’s own raw-capacity and RAID specification.

| Compatibility field | Official list example | Why it matters |
|---|---|---|
| Recommended model mapping | The current table lists Western Digital WD Red Pro WD240KFGX at 24 TB as recommended and includes F4-424 Max in its compatible-model list. | Preserve drive brand, series, exact model number, capacity, recommendation label and compatible NAS model as one relation. |
| Not-recommended label | The same table lists Western Digital Blue WD20EZRZ at 2 TB as not recommended for the models in that row, including F4-424 Max. | Keep `not recommended` distinct from physical drive-bay or SATA-form-factor compatibility. |
| Cross-page capacity difference | The current recommended-drive list includes a 24 TB WD Red Pro model for F4-424 Max, while the detailed NAS specification still states 22 TB × 4 for maximum internal raw capacity. | Retain each source value with its review date instead of calculating a new system capacity from the compatibility list. |
