Is the F4-425 Pro N350 right for you?
Heavier four-bay TOS workloads
N350 and N305 both have eight Gracemont cores. This N350 SKU ships with 16 GB versus the N305 SKU’s 8 GB; compare exact configuration and workload evidence before paying more.[1]
Fast shared storage with applicable test evidence
HWBusters tested four SATA SSDs in RAID 5; Macworld used SATA/NVMe SSDs. Neither establishes four-HDD RAID throughput, and two 5GbE ports do not automatically make one 10GbE transfer.[7][5][2]
The N305/8GB version is sufficient
Compare drive cost, the installed network path and workload evidence with your requirements before choosing this configuration.[1]

Notebookcheck

Notebookcheck F4-425 Pro N350 original test
Notebookcheck treats the Pro chassis as identical to F4-425 Plus; the review focuses on the N350 upgrade. Jellyfin hardware decoding of 4K60 worked in their tests. English and German Notebookcheck pages are the same experiment.

Notebookcheck F4-425 Pro N350 original test
Tested: TerraMaster-supplied F4-425 Pro with Intel Core 3 N350 (8 Gracemont cores, 3.9 GHz), 16 GB DDR5-4800 SO-DIMM, TOS 7 beta 7.0.0616 later updated to 7.0.0706. Not the N305/8 GB SKU. Drive models/count, RAID and LAN client are not disclosed in the text.
Applies to: Applies to F4-425 Pro N350; factory memory, drives, RAID, network and software conditions remain limited to the disclosed setup.
- Notebookcheck treats the Pro chassis as identical to F4-425 Plus; the review focuses on the N350 upgrade. Jellyfin hardware decoding of 4K60 worked in their tests.Source location: Verdict / Double the performance with the Intel N350
- CPU reached 94 °C under sustained load without throttling (Intel max 105 °C). Fan stayed quieter than HDD noise; users can raise fan speed. Hypercache cut a 610 KB image page from 2.8 s to 0.6 s over the internet in their Docker-website example.Source location: Double the performance… / Hypercache paragraph
- Ten Docker apps including Jellyfin, Immich and OwnCloud used 3.2 GB RAM; Immich photo ingest rose to 5.9 GB. A Jellyfin 4K stream did not noticeably move RAM. M.2 SSDs are not hot-swappable.Source location: RAM usage and SSD access paragraphs
| Measurement | Result | Conditions & source location |
|---|---|---|
| Sustained-load CPU peak | 94 °C | N350; no throttling reported; below 105 °C spec.CPU temperature paragraph + photo caption 90 °C |
| Jellyfin hardware decoding | 4K60 completed | N350/16 GB running Jellyfin; codec, bitrate and concurrent-stream count are not specified. Hardware decoding is not a demonstrated multi-stream Plex transcoding capacity.Integrated graphics / Jellyfin sentence |
| Hypercache Docker page load | 0.6 s vs 2.8 s | Simple website with 610 KB images, over the internet, Docker-hosted; not a LAN copy benchmark.Hypercache paragraph |
| Idle-ish RAM with 10 Docker apps | 3.2 GB; 5.9 GB during Immich ingest | TOS7 on 16 GB; one unit.RAM usage paragraph |
Limits to keep in mind
- English and German Notebookcheck pages are the same experiment.
- No four-HDD RAID throughput table in this brief Pro follow-up.
- TOS 7.0.0616 was a beta; the author says some Safari/resource-monitor issues were fixed in 7.0.0706.
- One unit, about one month; not a reliability rate.

TechRadar F4-425 Pro N350 original test
TechRadar says dual 5GbE and a third M.2 slot are the hardware story, but each M.2 is PCIe 3.0 x1 and dual 5GbE is not a single 10GbE client path. OpenClaw/Ollama setup failed in their attempt. HDD array MB/s in the article are calculated from drive ratings, not stopwatch copies.

Applies to: Applies to F4-425 Pro N350; factory memory, drives, RAID, network and software conditions remain limited to the disclosed setup.

Limits to keep in mind
- HDD array MB/s in the article are calculated from drive ratings, not stopwatch copies.
- OpenClaw local-model test failed; do not treat as a working AI NAS demonstration.
- HDMI is described as unused for media playback.
- Affiliate commission disclosed.
- Review dimensions use package size; official chassis dimensions take precedence. No measured power or calibrated acoustic result.
- Claims about extra N350 cores/architecture versus N305 are not adopted; both have eight Gracemont cores.

Macworld: N350/16 GB SSD-populated 5GbE copies
Single-port 5GbE SSD transfers were fast; bonding produced little benefit in this setup. Short Disk Speed Test writes and larger AmorphousDiskMark writes differed substantially. The adjacent CrystalDiskMark prose gives inconsistent write values and units; those prose values are excluded.

Macworld: N350/16 GB SSD-populated 5GbE copies
Tested: N350/16 GB, Seagate IronWolf SATA SSD plus two Crucial T710 NVMe drives, Btrfs. SATA capacity is printed with an apparent GB/TB typo and is not adopted. M4 Max Mac Studio via EnGenius ECS2512FP; separate PCWorld Intel Windows client mentioned. SSDs, not four HDDs.
Applies to: Direct for N350/16 GB hardware and 5GbE SSD-populated copies. Not a four-HDD RAID result. CrystalDiskMark 580 vs 470 MB/s write figures in adjacent sentences are internally inconsistent; retain the later 587/470 pair with that caveat.
- Single-port 5GbE SSD transfers were fast; bonding produced little benefit in this setup. Short Disk Speed Test writes and larger AmorphousDiskMark writes differed substantially.Source location: How does the F4-425 perform? and chart captions
- Backup jobs could stop when destination space ran out; the author also reports file-manager and app-state rough edges. The author used DLNA playback, but this does not establish Plex transcode or VM capacity.Source location: Software and verdict

Limits to keep in mind
- The adjacent CrystalDiskMark prose gives inconsistent write values and units; those prose values are excluded.
- No 450 GB transfer result appears in this N350 original. The earlier draft misattributed the F8 SSD Plus test; it has been removed.
- SSD workload; no four-HDD RAID benchmark. Exact drive capacities and pooling of each device are incompletely disclosed.
- USB-C diagnostic-only, dual-2.5GbE caption and broad security claims conflict with other evidence and are not adopted.

Limits to keep in mind
- Exact PC configuration and all benchmark profiles are not disclosed.
- Four SATA SSDs, not four HDDs; beta-era software and one review unit.
- Manufacturer 1010 MB/s aggregation claim and 20.9 dB(A) are not independent measurements.
- No controlled VM-concurrency or long-term reliability test.

Questions before buying
What does the original testing establish?
HWBusters tested four SATA SSDs in RAID 5; Macworld used SATA/NVMe SSDs. Neither establishes four-HDD RAID throughput, and two 5GbE ports do not automatically make one 10GbE transfer.[7][5][2]
Which system version will arrive?
Current manufacturer marketing advertises TOS 7, but the exact shipping build and update-package mapping were not verified. Review results apply to the versions recorded in each test.[1]
Are storage drives included?
No. These are diskless offers. Select suitable drives and allow for RAID overhead and an independent backup.[1]
Does N350 have more cores than N305?
No. Both have eight cores. This N350 factory SKU has 16 GB memory, compared with 8 GB on the separately listed N305 SKU.[1]
