F4-425 Pro N305: specifications and dated store comparison →Eight cores and dual 5GbE, with an 8GB configuration to verify
F4-425 Pro N305; factory 8 GB non-ECC SODIMM; four SATA bays and three M.2 slots; dual 5GbE.
The N305 F4-425 Pro combines four SATA bays, three M.2 slots and dual 5GbE for a home media server with extra services. AppleInsider tested the 8 GB version and reported useful media and combined-link performance, although its methods are incomplete. The single memory slot limits upgrade flexibility, and conflicting DDR4/DDR5 descriptions should be resolved before buying a replacement module. See the review evidence ↓
The current official table explicitly covers the N305: 8 GB non-ECC memory, up to 32 GB in one slot, and three PCIe 3.0 x1 M.2 sockets. SSDs can serve a separate pool; the 144 TB marketing total includes both SATA and NVMe positions before redundancy.[1]
AppleInsider reported about 800 MB/s over combined links and five simultaneous 4K-to-1080p Plex transcodes. Network mode, codecs, bitrate and HDR conditions were not fully disclosed, so these are observations to qualify rather than guarantees for a household.[4]
Follow any specification for its full conditions and sources.

The reviewer reported about 800 MB/s using both network links and three SSDs, plus five simultaneous 4K-to-1080p Plex transcodes without frame loss. Missing network and codec details limit how far those results can be generalized.
Read the original reviewTerramaster F4-425 Pro review: Excellent set-and-forget networking hardware
Tested: Explicit Intel N305, factory 8 GB, TOS 7. Four 4 TB drives described with an inconsistent brand/series name, plus a separate four-drive 24 TB WD Red Pro setup. Three unspecified SSDs for a wired Mac Studio M1 Ultra test; array and network configuration incompletely disclosed.
Applies to: Direct N305/8 GB hands-on review; exact benchmarking and memory-type limitations are retained.

Before you buy
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]
Verify CPU, factory RAM, new condition, seller and selected variant before checkout. Shipping, tax and final availability can change.[2][3]
DDR generation conflicts remain in the sources. Obtain the exact compatible module specification before purchasing a memory upgrade.[1]

No. The listed offers are new diskless enclosures with the stated factory memory. Add compatible data drives and a separate backup target.[1]
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]
No. There is one SODIMM slot, so a memory upgrade replaces the existing module. Resolve the conflicting DDR generation descriptions before buying RAM.[1]
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]
