F2-425 Plus N150: specifications and dated store comparison →Two HDD bays and three SSD slots, backed by several N150 tests
F2-425-PLUS-N150 · Intel N150 · 4-core · 8GB RAM · 3.5-inch SATA HDD / 2.5-inch SATA SSD / M.2 NVMe
The N150 F2-425 Plus suits a compact HDD archive with separate SSD storage and faster networking. Its 8 GB RAM, three M.2 slots and dual 5GbE ports are supported by several original tests, but results vary with file size, SSD placement and client links. Two SATA bays still limit HDD parity choices, and the dated TOS 6 reviews reveal photo-search and synchronization rough edges. See the review evidence ↓
Is the F2-425 Plus N150 right for you?
High-speed two-bay backup and file sharing
IT Pro’s SSD-pool Iometer test reached 4.6 / 3.9 Gbit/s read/write over 5GbE. PCMag’s two-HDD, 2.5GbE mixed folder reached 188 / 245 MB/s. CNX’s 4.7 Gbit/s iperf result tests networking, not file storage.[2][5][7]
TOS users who want 8GB and M.2 expansion
CNX’s mobile setup included its SSD in the data pool. Rebuilding the pool to use it as cache took another long synchronization. Cache improved sequential writes in that experiment, but random writes fell; a separate SSD pool may fit different workloads.[6][7]
You need four or more HDD bays
CNX used people/scene recognition and remote browsing, but phone sleep interrupted photo backup, search was case-sensitive, and TerraSync on Linux failed its version check. These are dated TOS 6 observations, not a current cross-platform verdict.[7]

TerraMaster F2-425 Plus
Tested: Intel N150, 8GB DDR5; pair of 10TB Seagate IronWolf HDDs; 2.5GbE switch to desktop; 4.9GB mixed music/video/photo/office folder. Default TRAID configuration, approximately 9.09 TB usable, around 12 hours initialization/synchronization; exact firmware and desktop specifications unstated.
Applies to: Exact N150 8GB two-bay Plus hardware. Throughput is 2.5GbE-limited, not dual-5GbE saturation.
- Wrote 245MBps and read 188MBps on the 4.9GB mixed folder; reviewer counted 57 App Center titles versus a much larger Asustor catalog.Source location: Performance Testing / App Center

Limits to keep in mind
- US pcmag.com returned Cloudflare 403; Canada page was the opened text.
- No dual-5GbE or NVMe-pool chart in the opened text.
- The summary widget calls networking 2.5GbE, but the chassis has dual 5GbE ports; 2.5GbE is the test switch. Generic RAID6/10 lists do not apply to two SATA drives alone.

TerraMaster F2-425 Plus NAS review – Part 2: Configuration, benchmarks, and AI-enhanced media storage
Phone initialization selected TRAID/Btrfs and included the SSD in the data pool. Separating it for cache required deleting/rebuilding the pool and another 15-hour synchronization. The 1 GB test showed faster sequential writes with cache, but slightly slower random writes.

TerraMaster F2-425 Plus NAS review – Part 2: Configuration, benchmarks, and AI-enhanced media storage
Tested: N150, 8 GB DDR5, TOS 6.0.794. One 4 TB HGST HDD of unspecified model, one refurbished 4 TB HPE MB4000GVY2K and Apacer AS2280P4 256 GB NVMe. Mobile initialization first combined all three drives in TRAID/Btrfs; reviewer deleted/rebuilt the pool using the two HDDs and single-SSD read/write Hyper Cache. Ubuntu 24.04 UP Xtreme i11 Edge client with CIFS 3.0 at 2.5GbE; a second Linux laptop for adaptive-load-balancing tests; iKOOLCORE R2 Max/QWRT for 5GbE iperf3.
Applies to: Exact N150 Plus sample. SMB numbers are 2.5GbE-limited; NVMe is PCIe 3.0 x1.
- Phone initialization selected TRAID/Btrfs and included the SSD in the data pool. Separating it for cache required deleting/rebuilding the pool and another 15-hour synchronization. The 1 GB test showed faster sequential writes with cache, but slightly slower random writes.Source location: Part 2, setup and Hyper Cache
- Approximately 5,000 photos backed up while the phone display remained active, but sleep interrupted progress. People/scene recognition helped, while case-sensitive search and missing synonyms made retrieval less polished.Source location: Part 2, Multimedia file synchronization and AI search
- Remote browsing worked from a Linux computer and cellular Android connection. TerraSync on Linux incorrectly rejected TOS 6.0.794 as too old; this failure is not generalized to Windows or macOS.Source location: Part 2, Remote access
- Part 1 teardown identified three M.2 slots, one DDR5 slot and two RTL8126 controllers. The main board has passive CPU cooling, but the NAS itself contains a chassis fan.Source location: Part 1, teardown
| Measurement | Result | Conditions & source location |
|---|---|---|
| SMB sequential read / write before and after cache | Mixed HDD+SSD pool: 279 / 110 MB/s; HDD pool + SSD cache: 277 / 206 MB/s | Original comparison table, iozone 1,000 MB test with 16 MB records over a single 2.5GbE path. Baseline includes the SSD as pool storage, not HDD-only.Part 2, Hyper Cache comparison |
| SMB 4K random read / write before and after cache | Mixed pool: 9.9 / 13.4 MB/s; HDD pool + cache: 12.4 / 10.5 MB/s | Same 1,000 MB test; cache did not improve random write.Part 2, Hyper Cache comparison |
| Two-client aggregate read / write | Approximately 249 / 325 MB/s | Two 2.5GbE clients with adaptive load balancing, separate 10,000 MB files and 16 MB records.Part 2, Link Aggregation |
| 5GbE raw network throughput | Approximately 4.70–4.71 Gbit/s per direction | 60-second iperf3 runs with R2 Max, including simultaneous bidirectional traffic. No 5GbE SMB test.Part 2, iperf3 output |
| Encrypted rsync file transfer | 161.66 MB/s progress rate | 2 GiB file over SSH; total-job output is slower, approximately 116.1 MB/s.Part 2, rsync output |
Limits to keep in mind
- Manufacturer supplied the NAS and sponsored one HDD. Parts 1 and 2 form one experiment group.
- The 5GbE result measures networking without filesystem work; 2.5GbE bonding is multi-client throughput.
- The resource monitor’s 900 MB/s reading is inconsistent with the linked 2.5GbE ports and is excluded.
- Single-SSD deferred-write caching is vulnerable to SSD or power failure; this test is not a recommendation to use it without protection.
- No measured noise/power or controlled transcoding capacity; results are specific to dated TOS 6 software.

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 Plus model’s three M.2 slots can instead form a separate SSD RAID 5 pool.[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]
