TRENDnet TEG-S562 vs QNAP QSW-2104-2S

Same recipe: unmanaged, fanless, 4× 2.5G + 2× 10G SFP+. Do not pick a winner without the live price.

TRENDnet is the street-price win plus lifetime / NDAA paper. QNAP adds a loop-detect LED, a 16K MAC table, and a NAS-brand halo. QNAP store at $129 versus Amazon TRENDnet at about $52 is not a close fight unless B&H has the QNAP at $80 again. Both are fanless and have no PoE. QNAP max 12 W, 12 V / 1 A. Single-SKU notes: TEG-S562 and QSW-2104-2S.

Skip

Skip paying $129 for the QNAP when the TRENDnet is $52 and you do not care about the badge. Skip QSW-M2108-2C (1× PWM fan, QNAP-store $349 and OOS). Skip QSW-1105-5T (empty shelf). Skip no-name 4×2.5G + 2×SFP+ toys. If you need eight 2.5G copper plus SFP+, that is a different hop.
