Exact product identity & open questions
- Manufacturer / exact MPN
- TerraMaster / F2-425[1]
- Configuration covered
- Diskless; factory 4GB DDR4; not F2-425 Plus[1]
- Current CPU identity: Store title N95 conflicts with the N5095 official PDF and original test units. Confirm the processor on the exact item before purchase.
- HDMI playback: No current supported media-player interface was verified; the reviewed TOS 6 units used console output.
- Evidence conflicts: HWBusters large-file elapsed-time chart exceeds its stated link limit; PCWorld’s AmorphousDiskMark target is ambiguous. Those figures are excluded.
- Historical source: Canon Rumors remains a retained earlier reading; this round’s original page was blocked.
- Current application limits: The full PDF is included, but generic RAID and link-aggregation rows exceed the physical two-drive/single-port arrangement. Confirm the exact TOS package and storage layout.
