Written 23 Aug 2026. Specs from TerraMaster product pages. Street from named snaps. I haven't used these.
Stay on the cheap quiet 2-bay unless you will use two faster ports: F2-425 vs F2-424
Stay on the cheap TOS 2-bay unless you will actually use two faster ports or solid-state cache. Skip the extra $125. The F2-425 stays the default.
Stay on the cheap quiet 2-bay unless you will actually use two faster ports or solid-state cache. F2-424 spec block: Intel N95, 4C/4T, 3.4 GHz burst, UHD Graphics, AES-NI. 8 GB DDR5-4800 SODIMM, one slot, official max 32 GB. Dual 2.5GbE. Dual M.2 2280 NVMe (PCIe 3.0 x1). HDMI 2.0b. Two USB 3.2 10 Gbps. 40 W brick. 2-year paper. Maker RAID 0 linear 283 MB/s on 2× 18 TB NAS HDDs. Standby noise claim 19.0 dB(A) at 1 m. Access 22 W / hibernation 11 W with 2× Seagate 4 TB ST4000VN008. Same TOS as F2-425, not DSM. SKU / EAN 693923614463.
F2-425 is still the N5095 / 4 GB DDR4 / one 2.5GbE / no M.2 chassis. Retailer titles mix “N95” onto that page; quote the spec block on that note. You are not buying a faster copy engine on two HDDs. You are buying dual LAN, NVMe cache, and DDR5 headroom.
What to buy
| Box | What it is | Street, 23 Aug 2026 | Buy if |
|---|---|---|---|
| TerraMaster F2-425 | N5095, 4 GB DDR4 / 16 GB max, one 2.5GbE, no M.2. TOS. 48 W brick. | Maker store $254.99 diskless this pass (list $299.99). Cart has been empty before. Print the live tag. | Default TOS 2-bay. You want 2.5G and x86 without paying for dual LAN or NVMe. |
| TerraMaster F2-424 | N95, 8 GB DDR5 / 32 GB max, dual 2.5GbE, dual M.2 2280, HDMI 2.0b. Same two SATA bays. TOS. | Maker store $379.99, out of stock this pass. No clean Amazon buy box on this fetch. | You will LACP two 2.5G ports or put NVMe cache in, and you will live with TOS. Not the first-NAS default. |
| QNAP TS-262A | Same N5095 class as F2-425, plus two M.2 and QTS. One 2.5GbE. | QNAP store $369 diskless. See that note. | You wanted M.2 cache and you wanted QTS, not TOS. |
Skip
Skip F2-424 as a “faster F2-425.” Two HDD RAID 1 will not fill two 2.5G ports. Skip it because the store title on F2-425 also says N95. Read the spec block. Skip Amazon drive bundles. Skip eBay lots. If you need DSM, that is still a DS224+, not this chassis. If you need 10G, that is a different box, not dual 2.5G. TOS is not DSM; don't buy this as a Synology substitute.
