Rank #8 in Best NAS Enclosure 2026: 10 Ranked, and Why the TB Maths Doesn't Add Up
TERRAMASTER F2-425 2-Bay NAS (Diskless)
Price and rating as shown on Amazon when we collected them. Both change.
The Terramaster F2-425 is a two-bay NAS enclosure with an Intel x86 quad-core processor, 4GB of RAM (non-ECC SODIMM) and a single 2.5GbE network port. It is sold diskless at £237.99, which means the drives are a separate purchase, and it finished at number 8 in this guide.
The number worth staring at is 60TB. The Terramaster listing breaks that down as 2 x 30TB, so 30TB in each bay — the arithmetic holds inside the ad, and it lands above the 18TB per bay that Synology's two-bay figure of 36TB implies, but below the 40TB per bay UGREEN claims on its own two-bay model. The ratings block is the stranger part: the ad reports 17 ratings, while the histogram shown alongside it adds up to 100 (11 two-star, 11 three-star, 15 four-star, 63 five-star), and those 100 are what produce the 4.3 average on display. Everything on this page is taken from the Amazon listing, not from any testing we have carried out.
