Identity
Compute and memory
Official specifications and applicable conditions.
| Processor | Intel Core i3-N305 · 8-core[1] |
|---|---|
| Factory memory | 32GB DDR5[1] Factory memory is kept separate from maximum supported capacity and from seller-installed upgrades. |
| Physical CPU cores | 8[2][8][9] |
| Factory memory | 32 GB[2] |
| Host memory ECC | No[1] Official platform and memory specification explicitly state non-ECC. |
| Official memory upgrade path | Replace the single module; up to 32 GB[1] The 32 GB configuration is already at the published limit; the 16 GB variant can replace its module with a supported 32 GB module. |
| Official memory limit | 32 GB[2] |
Storage and expansion
Official specifications and applicable conditions.
| Cataloged drive-bay count | 4[1] M.2 positions are listed separately and are not silently added to SATA bay count. |
|---|---|
| Supported drive layout | 3.5-inch SATA HDD / 2.5-inch SATA SSD / M.2 NVMe[1] |
| Replaceable storage drives | Yes[2] |
| M.2 expansion | Yes[2] |
| Official external drive enclosure expansion | Not verified[1] F4-424 Pro 32GB: evidence is still needed for an official external drive-enclosure expansion path; a USB port alone does not establish support. This remains unknown, not a confirmed no. |
| Physical M.2 slots | 2[2] |
| SATA without a mandatory model whitelist | Not verified[1] F4-424 Pro 32GB: evidence is still needed for the documented boundary of any mandatory manufacturer-model whitelist for SATA media; a compatibility list alone does not establish a technical lock. This remains unknown, not a confirmed no. |
| M.2 without a mandatory model whitelist | Not verified[1] F4-424 Pro 32GB: evidence is still needed for the documented boundary of any mandatory manufacturer-model whitelist for M.2 media; an omitted restriction does not establish unrestricted support. This remains unknown, not a confirmed no. |
Network
Official specifications and applicable conditions.
| Installed Ethernet | 2 × 2.5GbE[1] Multiple ports do not guarantee one client the sum of their link rates. |
|---|---|
| Fastest installed single network port | 2.5 Gbps[2] |
| Official network upgrade path | No PCIe NIC expansion slot[1] Two built-in 2.5GbE ports; untested USB NIC suggestions are not an official upgrade path. |
Software and data protection
Official specifications and applicable conditions.
| Factory operating system | TOS; current product page advertises TOS 7[2] Exact shipping build and update-package mapping were not verified; dated reviews identify their tested version separately. |
|---|---|
| RAID support | Yes[1] The exact-model official table publishes Supported RAID Types: TRAID, Single, JBOD, RAID 0, RAID 1, RAID5, RAID 6, RAID 10. This confirms the listed storage modes independently of the exact installed TOS build number. |
| Backup through the graphical interface | Yes[1][4] The exact-model page identifies TOS, and the official TOS 7 Duple Backup guide documents its graphical task interface. Package availability and menus can still vary by installed build. |
| Backup to an independent target | Yes[1][4] The exact-model page identifies TOS, and the official TOS 7 Duple Backup guide documents remote TNAS, file-server and cloud destinations outside the source enclosure. |
| Documented restore path | Yes[1][4] The exact-model page identifies TOS, and the official TOS 7 Duple Backup guide provides restore tasks from existing jobs and retained .duple data. |
| Scheduled backup | Yes[1][4] The exact-model page identifies TOS, and the official TOS 7 Duple Backup guide documents task execution schedules. |
| Restore from snapshots | Shared-folder snapshots on Btrfs[1] The model table marks LUN Snapshot unavailable; generic TOS help does not confirm LUN support on this model. |
| Version retention | Yes[1][4] The exact-model page identifies TOS, and the official TOS 7 Duple Backup guide documents multi-version backup, version selection and retention counts. |
| Immutable protection | HyperLock File System listed for TOS 7; enforcement details not verified[1] Model table lists HyperLock, but retention and administrator-deletion boundaries require the installed feature documentation. |
| Remote snapshot replication | Verify model/package support for the selected target[1] Generic TOS help describes replication, but the model table marks LUN snapshots unavailable. |
| Native endpoint restore | Endpoint restoration workflow not independently verified[1] Backup app availability and a file restore path do not alone establish full endpoint recovery. |
| Official system update path | Current product page advertises TOS 7; exact update package not verified[1] Support download service returned an error and release-topic pages were blocked. This is a package-verification gap, not proof that official updates are unsupported. |
| System status interface | Yes[1][6] The exact-model page identifies TOS, and the official TOS 7 Device Monitoring guide documents hardware, storage, resource and network status views. |
| System log interface | Yes[1][7] The exact-model page identifies TOS, and the official TOS 7 System Logs guide documents a categorized log interface. |

Exact product identity & open questions
- Product ID
- terramaster-f4-424-pro[1]
- Exact MPN or manufacturer configuration ID
- F4-424 Pro 32GB[1]
- Model
- F4-424 Pro 32GB[1]
- Factory compute and memory
- Intel Core i3-N305 · 8-core; 32GB DDR5[1]
- Storage layout
- 3.5-inch SATA HDD / 2.5-inch SATA SSD / M.2 NVMe[1]
- Current software behavior: The directly inspected original tests use TOS 5/5.1. Current TOS 7 package mapping and whether those historical issues are resolved were not verified.
- Workload capacity: No controlled VM/container concurrency, full recovery drill or complete Plex codec matrix was established.
- Manufacturer versus measured power: The official 4 TB-drive power rating differs from the four-20-TB review configuration; neither is a universal operating figure.
- Model naming in reviews: NASCompares and TechRadar repeatedly name N300; the official specification and ComputerBase identify N305. Conflicting CPU/lane claims are not adopted.
