TERRAMASTER F8 SSD Plus, eight M.2 bays and no SATA bay at all review

The only all-solid-state enclosure on this shelf: eight M.2 NVMe bays, no SATA bay at all, in six hundred grams — and the only listing here that names an off-site backup arrangement.

By Jean-Benoit Buisson

Eight bays, and not one of them takes a hard disc. The second bullet states eight M.2 2280 NVMe slots, each up to 8 TB, for 64 TB in total — and the arithmetic holds. No SATA bay appears anywhere on the page. Every other enclosure on this shelf is built around SATA bays, with at most two M.2 slots alongside as a cache or a fast volume; this one has inverted the arrangement entirely, and its bay count and its solid-state slot count are the same number.

What that buys is in the weight. Six hundred grams, and 175 by 140 by 61 mm (2.40 in). The four-bay UGREEN DXP4800 GT on this shelf weighs 6,610 grams for half the bays. The second bullet reaches for similes rather than figures — about the size of a paperback, no heavier than two telephones — but the record bears them out. Eight bays that fit on a shelf beside books is a different object from a four-bay box that needs its own corner.

The processor is an Intel Core i3-N305: eight cores, eight threads, turbo to 3.4 GHz, with UHD Graphics, stated in the first bullet. That is the highest core count on this shelf. The DXP4800 GT publishes four cores, eight threads and 3.70 GHz, so the two split the honours — more cores here, a higher clock there — and both are published with enough detail to be compared, which nothing else on this shelf manages.

Sixteen gigabytes of DDR5 at 4800 MHz is the largest memory supplied with any empty enclosure here, and the only DDR5. The GT supplies 8 GB of DDR4 and names a 64 GB ceiling; this page names no ceiling, and says memory expansion is a two-minute tool-free job.

The network is one 10GbE port at up to 1024 MB/s, stated in the first bullet. Singular. The GT publishes two at that rate and an aggregate figure for the pair, so on this line the GT is ahead.

The fifth bullet is the one that matters most for this shelf’s editorial line. It names the TerraMaster Business Backup Suite and its five parts: Centralized Backup, TerraSync for server and computer synchronization, Duple Backup for off-site recovery, CloudSync, and Snapshot for ransomware protection. Off-site recovery, named outright. The intro to this section says that carrying on through a drive failure is a different thing from having the data in a second place, and that no redundancy level substitutes for a copy on separate hardware. Twenty-one listings sit on this shelf and this is the only one that names an arrangement for the second place.

Which makes the omission on the same page conspicuous: no redundancy level is published at all. No RAID number, no TRAID, nothing. On an eight-bay machine, the arrangement the eight drives are put into is the first question, and the page answers it nowhere.

Cooling is described in more detail than anywhere else here: convection active cooling, a heat sink on each individual SSD, and silent fans, across the third and fourth bullets. The third also gives standby noise below 19 dB — a second acoustic figure for this shelf, where the four-bay TerraMaster F4-425 publishes 22 dB(A). The two are not comparable as they stand: one is a standby figure and the other is not qualified, and neither page gives a distance or a load.

No figure in watts, no USB socket counted, and no operating system named — the suite is named, the system that runs it is not. At $764.99 on Amazon.com on October 26, 2026 it was the fourth-highest price on this shelf, after the DS723+ bundle, the QNAP TS-464 and the UGREEN DXP6800 Plus.

Where it holds up, and where it stops

Strengths

The only all-solid-state enclosure on this shelf: eight M.2 NVMe bays and no SATA bay at all
The only listing on this shelf that names an off-site backup arrangement, which is the thing no redundancy level replaces
The highest core count here at eight, with the thread count and the turbo frequency both published
Sixteen gigabytes of DDR5, the largest memory supplied with an empty enclosure on this shelf
Six hundred grams for eight bays, against 6,610 g (233.2 oz) for a four-bay unit on the same shelf
A heat sink on each individual drive, named alongside convection cooling and silent fans

Compromises

No redundancy level published at all — no RAID number, no TRAID — on an eight-bay machine
One 10GbE socket where the four-bay UGREEN on this shelf publishes two and an aggregate figure
No USB socket counted and no operating system named, only the backup suite that runs on it
The 19 dB is a standby figure, so it does not describe the machine while it is working
No figure in watts, on an eight-drive machine whose two middle bullets are entirely about heat

Specifications

Bay count	Eight — stated in the title and in the second bullet as eight M.2 2280 NVMe slots, each taking up to 8 TB for 64 TB in total. The arithmetic holds, and it is the highest bay count on this shelf
Drive interface	M.2 2280 NVMe only — stated in the second bullet. No SATA bay appears anywhere on the page, which makes this the only all-solid-state enclosure on this shelf; every other listing here is built around SATA bays
Solid-state slot count	Eight, which is the same as the bay count — the two figures coincide because every bay is an M.2 slot. Each takes up to 8 TB, stated in the second bullet
Processor	Intel Core i3-N305, eight cores and eight threads with a turbo frequency up to 3.4 GHz, with UHD Graphics — stated in the first bullet. It is the highest core count on this shelf; the UGREEN DXP4800 GT here publishes four cores, eight threads and a higher clock at 3.70 GHz
Memory	16 GB of DDR5 at 4800 MHz — stated in the first bullet. It is the largest memory supplied with an empty enclosure on this shelf and the only DDR5 here. No ceiling is published; the second bullet says expansion is tool-free and takes two minutes
Ethernet port count	One — the first bullet names a 10Gbps Ethernet port in the singular. The DXP4800 GT on this shelf publishes two at the same rate
Port speed	10GbE, given as up to 1024 MB/s — stated in the first bullet. No aggregate figure is offered, because there is only one socket to aggregate
USB ports	Not published on the listing — no USB socket is named or counted in the title or in any of the five bullets
Supported redundancy levels	Not published on the listing — no RAID number, no TRAID and no array arrangement of any kind is named, on an eight-bay machine where the arrangement is the first question. Carrying on through a drive failure is in any case a different thing from holding the data in a second place, and this page does name an arrangement for the second place
Published operating system	Not named — the fifth bullet names the TerraMaster Business Backup Suite and its five parts: Centralized Backup, TerraSync, Duple Backup for off-site recovery, CloudSync and Snapshot for ransomware protection. The system that runs them is never called anything
Stated idle power	Not published on the listing — no figure in watts appears, on a machine whose third and fourth bullets are both about heat
Stated acoustic figure	Below 19 dB in standby — stated in the third bullet. It is the second acoustic figure on this shelf; the four-bay TerraMaster F4-425 here publishes 22 dB(A) without a condition attached, so the two describe different states and neither page gives a distance or a load
Stated dimensions	Not published in the bullets as figures — the second compares the unit to a paperback book and to two telephones. The product record carries 175 by 140 by 61 mm (2.40 in) and 600 g (21.2 oz), which is a tenth of the weight of the four-bay UGREEN on this shelf

The questions that come up before an order

Can it take hard discs?

No. The second bullet gives eight M.2 2280 NVMe slots and the page names no SATA bay anywhere. It is the only enclosure on this shelf built that way.

What RAID levels does it support?

The listing does not say. No RAID number and no array arrangement of any kind appears on the page, which on an eight-bay machine is the question left open.

What does Duple Backup mean?

The fifth bullet names it as off-site recovery, within the TerraMaster Business Backup Suite. It is the only arrangement for holding the data somewhere else that any listing on this shelf names, and it is a different thing from an array surviving a dead drive.

How does it compare with the UGREEN DXP4800 GT here?

This one has eight bays to the GT’s four, eight cores to its four, and DDR5 where the GT has DDR4. The GT has the higher clock at 3.70 GHz, two 10GbE sockets to this one’s one, a published 64 GB memory ceiling and SATA bays that take hard discs.
