Identity
Compute and memory
Official specifications and applicable conditions.
| Processor | Realtek RTD1619B · ARMv8.2 Cortex-A55 · four cores at 1.7 GHz[17] Fixed 2 GB RAM; processor identity from the model specification. |
|---|---|
| Factory memory | 2GB RAM[1] Factory memory is kept separate from maximum supported capacity and from seller-installed upgrades. |
| Physical CPU cores | 4[2][4] |
| Factory memory | 2 GB[2][4] |
| Host memory ECC | Not verified[17] The official specification does not state host ECC support. Absence of a claim is not proof of a negative. |
| Official memory upgrade path | No[2][4] |
| Official memory limit | 2 GB[17] Fixed memory; no upgrade slot. |
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 | 4 × 3.5/2.5-inch SATA HDD/SSD; no M.2 slot[1] |
| Replaceable storage drives | Yes[2][4] |
| M.2 expansion | No[2][4] |
| Official external drive enclosure expansion | Not verified[1] F4-212: 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 | 0[2][4] |
| SATA without a mandatory model whitelist | Not verified[1] F4-212: 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 applicable — no M.2 slots[17] The model has no M.2 positions. |
Network
Official specifications and applicable conditions.
| Installed Ethernet | 1 × 1GbE[1] Multiple ports do not guarantee one client the sum of their link rates. |
|---|---|
| Fastest installed single network port | 1 Gbps[2][4] |
| Official network upgrade path | No PCIe NIC slot; one built-in 1GbE port[17] No supported alternative upgrade path verified. |
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[5][2] |
| Backup through the graphical interface | Yes[1][6] 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][6] 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][6] 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][6] 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[17] Model table lists shared-folder snapshots but marks LUN snapshots unavailable. Generic TOS help does not override that model limitation. |
| Version retention | Yes[1][6] 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 | Version locking is documented; timed immutability and administrator-deletion boundaries are not confirmed[1][6] The official TOS 7 Duple Backup guide says a locked backup version cannot be replaced or deleted. The evidence does not establish a timed immutable period or all administrator boundaries, so this remains a buying-relevant gap. |
| Remote snapshot replication | Package and model support must be checked[17] Generic TOS Snapshot guide describes remote replication; exact F4-212 LUN snapshot capability is not confirmed. |
| 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[5] 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][9] 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][10] The exact-model page identifies TOS, and the official TOS 7 System Logs guide documents a categorized log interface. |
