Identity
Compute and memory
Official specifications and applicable conditions.
| Processor | Intel N95 · 4-core[1] |
|---|---|
| Factory memory | 8GB RAM[1] Factory memory is kept separate from maximum supported capacity and from seller-installed upgrades. |
| Physical CPU cores | 4[3] |
| Factory memory | 8 GB[2] |
| Host memory ECC | Not verified[1] F2-425 Plus N95: evidence is still needed for host-path ECC in the factory configuration; on-die ECC does not establish host ECC. This remains unknown, not a confirmed no. |
| Official memory upgrade path | Not verified[1] The current detailed specifications identify an N150 processor, while the selected variant is N95. Exact N95 hardware support and slot limits have not been established; N150 specifications are not substituted. |
| Official memory limit | Not confirmed for N95. The Plus PDF lists 32 GB on the N150 column; Intel N95 ARK was access-denied this round.[1][16] Evidence boundary: the opened exact-model official page did not publish or establish this field. The citation records the checked evidence boundary, not a confirmed feature. The current detailed specifications identify an N150 processor, while the selected variant is N95. Exact N95 hardware support and slot limits have not been established; N150 specifications are not substituted. |
| Memory generation | 8 GB DDR5 in N95-specific product prose[1] Do not apply the N150 memory-limit table to N95. Confirm compatible module details before purchase. |
Storage and expansion
Official specifications and applicable conditions.
| Cataloged drive-bay count | 2[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 — removable SATA drive trays[1] The N95 product prose and exact diskless merchant listing identify the same two/four removable SATA-bay arrangement. |
| M.2 expansion | Yes[11][12] |
| Official external drive enclosure expansion | TerraMaster USB DAS expansion advertised for this Plus family[1] Current shared product page explicitly supports USB DAS expansion; exact supported enclosure, pool and TOS combinations need confirmation. |
| Physical M.2 slots | 3[10][11][12] |
| SATA without a mandatory model whitelist | Not verified[1] F2-425 Plus N95: 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] F2-425 Plus N95: 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 × 5GbE[1] Multiple ports do not guarantee one client the sum of their link rates. |
|---|---|
| Fastest installed single network port | 5 Gbps[2] |
| Official network upgrade path | No official faster-NIC upgrade path verified[1] The shared N150 sheet cannot establish a separate N95 expansion-slot specification. |
Software and data protection
Official specifications and applicable conditions.
| Factory operating system | TOS; verify the supplied version[1] N95-specific prose mentions TOS 6 alongside shared TOS 7 marketing. A shipping build and exact download package were not verified. |
|---|---|
| Published RAID types | Two SATA drives: Single, JBOD, RAID 0/1 or TRAID; separate three-M.2 RAID 5 pool advertised[1] Generic shared RAID6/10/TRAID+ lists do not apply to two SATA drives alone. |
| RAID support | Yes[1] The opened exact-model page publishes TRAID storage and redundancy support. The current table lists RAID 0/1/5/6/10 and TRAID/TRAID+. Available layouts still depend on the installed SATA/M.2 media and drive count. |
| 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 | Yes[1][7] The exact-model page identifies TOS, and the official TOS 7 Snapshot guide documents local and remote snapshot restore paths. It requires a supported TOS version, BTRFS and an applicable folder or LUN configuration. |
| 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 | HyperLock-WORM protection is published; configuration and administrator boundaries need verification[1] The current exact-model page publishes HyperLock-WORM protection. The opened page does not fully establish setup prerequisites, enforcement against every administrator path or the effective retention setting, so this remains a buying-relevant gap. |
| Remote snapshot replication | Yes[1][7] The exact-model page identifies TOS, and the official TOS 7 Snapshot guide documents scheduled duplication and snapshot replication to a remote TNAS, subject to its stated setup requirements. |
| 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][8] 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][9] The exact-model page identifies TOS, and the official TOS 7 System Logs guide documents a categorized log interface. |

| Dimensions | 150 × 122 × 219 mm (H×W×D)[1][16] From F2-425 Plus PDF chassis row. That PDF processor column is N150; N95 is the other Shopify variant on the same PDP. |
|---|---|
| Weight | Net 2.2 kg; gross 3.1 kg[1][16] PDF Weight row on the shared Plus sheet, not an N95-only column. |
| Power supply and consumption | N95 consumption not verified; shared N150 sheet: 48 W adapter, 31 / 12 W access / hibernation[1] Related N150 factory measurements, not N95 measured power. |
| Acoustic conditions | 20.0 dB(A) standby footnote on the N150 Plus sheet (2 SATA, 17.3 dB(A) room, 1 m)[1][16] Shared chassis sheet; not an N95 lab measurement. |
