ModelF2-425 Plus N95[1]

Compute and memory

Official specifications and applicable conditions.

Compute and memory specifications
ProcessorIntel N95 · 4-core[1]
Factory memory8GB RAM[1]

Factory memory is kept separate from maximum supported capacity and from seller-installed upgrades.

Physical CPU cores4[3]
Factory memory8 GB[2]
Host memory ECCNot 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 pathNot 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 limitNot 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 generation8 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.

Storage and expansion specifications
Cataloged drive-bay count2[1]

M.2 positions are listed separately and are not silently added to SATA bay count.

Supported drive layout3.5-inch SATA HDD / 2.5-inch SATA SSD / M.2 NVMe[1]
Replaceable storage drivesYes — 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 expansionYes[11][12]
Official external drive enclosure expansionTerraMaster 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 slots3[10][11][12]
SATA without a mandatory model whitelistNot 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 whitelistNot 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.

Network specifications
Installed Ethernet2 × 5GbE[1]

Multiple ports do not guarantee one client the sum of their link rates.

Fastest installed single network port5 Gbps[2]
Official network upgrade pathNo 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.

Software and data protection specifications
Factory operating systemTOS; 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 typesTwo 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 supportYes[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 interfaceYes[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 targetYes[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 pathYes[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 backupYes[1][6]

The exact-model page identifies TOS, and the official TOS 7 Duple Backup guide documents task execution schedules.

Restore from snapshotsYes[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 retentionYes[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 protectionHyperLock-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 replicationYes[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 restoreEndpoint restoration workflow not independently verified[1]

Backup app availability and a file restore path do not alone establish full endpoint recovery.

Official system update pathCurrent 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 interfaceYes[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 interfaceYes[1][9]

The exact-model page identifies TOS, and the official TOS 7 System Logs guide documents a categorized log interface.

Physical, power and acoustics specifications
Dimensions150 × 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.

WeightNet 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 consumptionN95 consumption not verified; shared N150 sheet: 48 W adapter, 31 / 12 W access / hibernation[1]

Related N150 factory measurements, not N95 measured power.

Acoustic conditions20.0 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.

  • Exact N95 original test: No applicable N95 test was located; N150 throughput is not substituted.
  • N95 memory support: Capacity is 8 GB and the N95 prose says DDR5, but the exact supported maximum and upgrade procedure were not verified.
  • Shared specification: Detailed N150 power/chassis/software figures are explicitly related evidence, not an independently verified N95 sheet.
  • Current software and recovery: N95 TOS 6 prose and TOS 7 family marketing coexist. Precise package mapping, full endpoint restore and retention enforcement remain unverified.
