F2-425: specifications and dated store comparison →An affordable two-bay backup server with one 2.5GbE link
Diskless F2-425; factory 4GB DDR4; not F2-425 Plus.
The F2-425 offers a useful starting point for home backups and light media services: two SATA bays, replaceable 4 GB RAM and one 2.5GbE port. Wired SSD tests approached the link limit, while app setup sometimes needed attention. Confirm the CPU before ordering: the current store title says N95, but its detailed specification and the tested units identify N5095. See the review evidence ↓
Is the F2-425 right for you?
Home backup
Hardware Busters measured roughly 270 / 250 MB/s large-file read/write using two SATA SSDs. TechRadar’s 60 / 50 MB/s result used a different Wi-Fi path, so it does not measure the wired port limit.[2][4]
Light apps
A mirror or two-drive TRAID trades capacity for drive-failure redundancy. There are no M.2 slots or second network port; optional USB DAS expansion needs a supported configuration and is not an independent backup.[1][9]

TerraMaster F2-425 NAS Review
The two-SSD mirror approached the single 2.5GbE limit in synthetic and large-file tests. A conflicting elapsed-time chart is excluded because its stated 24.78 GB / 50–57 seconds would exceed that link.

TerraMaster F2-425 NAS Review
Tested: Two ADATA SU800 240GB SATA SSDs; RAID 1 EXT4 for network tests; TOS 6.0.783–01200; 2.5GbE. Factory 4GB described; no RAM upgrade stated. Client has a PCIe Gen4 x4 NVMe drive; model and CPU unspecified.
Applies to: Useful disclosed SSD test; HDD noise and speed differ.
- The two-SSD mirror approached the single 2.5GbE limit in synthetic and large-file tests. A conflicting elapsed-time chart is excluded because its stated 24.78 GB / 50–57 seconds would exceed that link.Source location: Pages 5–6 and original transfer charts
- The 80 mm fan was measured at 1 m in a quiet chamber. Low-speed operation was quiet with SSDs; this does not predict HDD chatter. The HDMI output showed system information only.Source location: Pages 6–7
| Measurement | Result | Conditions & source location |

| CrystalDiskMark 8.0.5 sequential read / write | Q8T1: 292.45 / 292.01 MB/s; Q1T1: 264.92 / 282.36 MB/s | Five passes, 1 GiB, SEQ1M; two ADATA SU800 240 GB SSDs, RAID 1, EXT4, TOS 6.0.783–01200, 2.5GbE.Page 6, cdm_benchmark.png |
| CrystalDiskMark 4K random read / write | Q32T1: 196.63 / 149.50 MB/s; Q1T1: 0.39 / 36.90 MB/s | Same 1 GiB SSD-mirror test; low-queue read is the displayed 0.39 MB/s, not silently corrected.Page 6, cdm_benchmark.png |
| ATTO 4.01 1 MB block read / write | 279.48 / 279.48 MB/s | 256 MB test, queue depth 4, Direct I/O enabled; network testing_folder path.Page 6, atto_benchmark.png |
| 3,100-file, 7.17 GB read / write time | 95 / 127 seconds | 2.5GbE SSD RAID 1; small-file chart. Large-file elapsed times in the same chart conflict with link capacity and are excluded.Page 6, raid1_pc.png |

| Boot / reboot / shutdown | 57 / 59 / approximately 2 seconds | Tested TOS 6 configuration.Page 6, Boot, Reboot & Shut Down |
Limits to keep in mind
- Client hardware and meter models not disclosed.
- Affiliate links; sample-provision terms not found.
- The 24.78 GB copy-time chart implies more than 2.5GbE capacity and conflicts with the prose; its large-file seconds are not adopted.
- No measured Plex stream count or current TOS 7 test; general TRAID+ language does not enable dual parity on two SATA drives.

TerraMaster F2-425 review: A powerful NAS box for streaming & backups
SMB Centralized Backup was useful; app installation and file-manager workflow caused friction.

TerraMaster F2-425 review: A powerful NAS box for streaming & backups
Tested: Single 2TB SATA SSD, model unspecified; factory 4GB described; 2.5GbE. Mac Studio M4 Max used for SMB backup example; exact TOS build unspecified.
Applies to: Single-drive SSD benchmark and backup usability.
- SMB Centralized Backup was useful; app installation and file-manager workflow caused friction.Source location: Software and conclusion
- App installation obstructed navigation in the file manager, and a rubber foot detached. The reviewer successfully used Centralized Backup with SMB shares; this is not an endpoint bare-metal restore test.Source location: Software and conclusion
| Measurement | Result | Conditions & source location |
|---|---|---|
| Blackmagic Disk Speed Test read / write | 262.4 / 268.3 MB/s | Single 2 TB SATA SSD; model and exact test size unspecified. Article associates this chart with its F2-425 SMB test.Original TerraMaster-F2-425-26.png |
Limits to keep in mind
- HDMI was terminal-only under tested software.
- Wrong USB and raw-capacity prose excluded in favor of official specifications. Affiliate links.
- The separate AmorphousDiskMark image displays Macintosh HD / Apple SSD labels. Its 294.00 / 202.50 MB/s result is not adopted as confirmed NAS-target data.
- The retained JSON-LD gives a 2025-10-09 publication/update; the previous draft’s May 2026 update date was not substantiated in this capture.

- Windows initialization needed manual TOS upload; Ubuntu setup was smoother. Docker web services and scheduled cloud backups worked.Source location: Setup and software
Limits to keep in mind
- Review unit supplied and affiliate commission disclosed.
- Modified-fan temperatures excluded from stock results; no controlled sustained-throughput figure.
- This source remains a retained earlier reading: live and saved current captures are HTTP 403/challenge pages. Parent did not independently reread its full article this round.

Terramaster F2-425 2-Bay NAS Review
Setup was short with tool-less trays. Heavy file copies made the UI less responsive for Plex browsing at the same time. No numeric throughput table.

Terramaster F2-425 2-Bay NAS Review
Tested: N5095, factory 4 GB; initially a spare 1 TB HDD, later 12 TB enterprise HDDs. Drive models, later drive count, RAID, client and exact TOS build were not disclosed.
Applies to: Exact F2-425 class, qualitative only.
- Setup was short with tool-less trays. Heavy file copies made the UI less responsive for Plex browsing at the same time. No numeric throughput table.Source location: Speeds when transferring / only downside
- Initial setup took under about 30 minutes. The 1 TB drive was subjectively quieter than the later enterprise drives; occasional Plex browsing delays appeared during large copies.Source location: Setup, noise and multitasking observations
Limits to keep in mind
- No named disks, RAID, or client path.
- Not a substitute for HWBusters/PCWorld numbers.

Plan the whole storage budget
Add suitable drives, an independent backup and any client/switch upgrades. RAID redundancy keeps some drive failures from stopping service; it does not replace a separate copy.[1]

Questions before buying
Are data drives included?
No. The listed offers are new diskless enclosures with the stated factory memory. Add compatible data drives and a separate backup target.[1]
Which software version should I expect?
The current product pages advertise TOS 7, while dated reviews and some specification text refer to earlier versions. Confirm the shipping build and required apps for the exact CPU and memory variant.[1]
Can two SATA drives provide RAID 5 or RAID 6?
No. Two SATA drives support a mirror or a two-drive TRAID layout, but not three/four-drive parity modes. The base F2-425 has no M.2 slots.[1]
Do multiple Ethernet ports guarantee faster copies to one computer?
No. Faster transfers depend on the client, workload and supported network configuration. Multi-client bonding results and network-only tests are not interchangeable with a single-computer file copy.[1]
