Terramaster D1 Buyers Guide – D1 SSD vs D1 SSD PLUS vs D1 SSD Pro

TerraMaster is a storage hardware brand best known for NAS, DAS, and direct-attached expansion products aimed at home users, content creators, small offices, and prosumer workloads. While NAS devices remain the better choice for shared network storage, remote access, multi-user collaboration, and always-on services, DAS products are often the more practical option when the priority is direct speed, portability, simplicity, and lower setup complexity. An M.2 NVMe SSD enclosure such as the TerraMaster D1 range is designed to connect directly to a host system over USB or Thunderbolt, making it more suitable for fast local transfers, field backup, editing work, boot drives, and quick storage expansion without the overhead of network configuration. The D1 range is currently split across 3 tiers: the D1 SSD, D1 SSD Plus, and D1 SSD Pro. All 3 are diskless single-slot M.2 2280 NVMe SSD enclosures supporting up to 8TB drives, but they differ significantly in interface bandwidth, chassis design, target workload, and price. The standard D1 SSD is the rugged USB 10Gbps option, the D1 SSD Plus moves to USB4 40Gbps for higher transfer speeds, and the D1 SSD Pro is the Thunderbolt 5 / USB 80Gbps model aimed at the fastest single-drive workflows.

TerraMaster D1 SSD – The 10Gb/s Budget One!

The TerraMaster D1 SSD is the entry-level model in the D1 range, using a single M.2 2280 NVMe SSD slot and a USB 10Gbps interface. This places it in a different category from the Plus and Pro models, as it is not intended to chase the highest possible external SSD speeds. Instead, it is aimed more at users who need a compact, portable NVMe enclosure for everyday transfers, local backups, field storage, and general-purpose expansion.

TerraMaster lists maximum sequential performance at up to 1020MB/s read and 1010MB/s write when tested with a Samsung 990 Pro 4TB SSD, which is close to the expected practical limit of USB 3.2 Gen 2 storage.

The main point of difference with this model is the enclosure design. The D1 SSD uses a unibody aerospace-grade aluminum alloy shell and is rated at IP67 for dust and water resistance. TerraMaster also states that the enclosure can withstand up to 1.2 tons of pressure, which gives it a more rugged profile than a typical low-cost NVMe USB enclosure.

That makes it better suited to users who regularly move drives between locations, carry storage in a work bag, or need something for outdoor shoots, site work, travel, or emergency backups. It is still a single-drive enclosure, so it should not be treated as a complete backup strategy on its own, but the physical protection is clearly one of its main selling points.

Cooling is handled passively, with the metal body functioning as the heatsink rather than relying on a small internal fan. TerraMaster describes the design as offering 2.5x the usual heat dissipation area, and the lack of a fan also means there is no operating noise from the enclosure itself. The D1 SSD supports PCIe 3.0, 4.0, and 5.0 M.2 2280 NVMe SSDs up to 8TB, although the external USB 10Gbps connection will cap performance long before a modern high-end NVMe SSD reaches its own internal limits. File system support includes NTFS, APFS, Mac OS, FAT32, EXT4, and exFAT, while official operating system support is listed for Windows, macOS, and Linux.

TerraMaster D1 SSD Plus – The Perfect Middle!

The TerraMaster D1 SSD Plus is the middle option in the D1 range, moving from the USB 10Gbps connection of the standard D1 SSD to a USB4 40Gbps interface. This makes it a more suitable choice for users who want a compact single-drive NVMe enclosure but need substantially higher transfer speeds for larger files. TerraMaster positions this model around portable creative workflows, Mac mini storage expansion, macOS boot drive use, Windows workstation cache storage, and general high-speed external storage.

The company lists tested speeds of up to 3853MB/s read and 3707MB/s write, though the formal specification table gives 3641MB/s read and 3498MB/s write with a Samsung 990 Pro 4TB SSD.

The D1 SSD Plus keeps the same basic single-drive structure as the rest of the range, supporting 1 M.2 2280 NVMe SSD with PCIe 3.0, 4.0, or 5.0 compatibility and a maximum internal raw capacity of 8TB. The higher-speed USB4 connection makes a more obvious difference when working with large video files, project folders, image libraries, and other data sets where USB 10Gbps can become a bottleneck.

It is also compatible with Thunderbolt 5, Thunderbolt 4, Thunderbolt 3, USB4, USB 3.2, USB 3.1, and USB 3.0, although real-world performance will depend heavily on the host port, cable, SSD, file system, and operating system. TerraMaster notes that some Windows computers with Thunderbolt 3 may have incomplete USB4 support, which can lead to recognition problems or reduced speeds.

The enclosure uses a fanless aluminum alloy chassis, with TerraMaster claiming 3x the typical heat dissipation area for passive cooling. This means the drive remains silent in use, while the metal body handles heat transfer from the installed NVMe SSD. At 246g, it is heavier than the standard D1 SSD, but still portable enough for laptop bags, travel kits, and desk-to-desk workflows. Unlike the rugged standard D1 SSD, the Plus model is not presented around IP67 protection or crush resistance, with the emphasis instead placed on speed, broad protocol compatibility, quiet cooling, and electrical protection against short circuits, voltage surges, and electrostatic discharge.

---

TerraMaster D1 SSD Pro – The INSANE one

The TerraMaster D1 SSD Pro is the highest-end model in the D1 range, moving the enclosure platform up to USB 80Gbps and Thunderbolt 5 class connectivity. This places it well above the D1 SSD Plus in available interface bandwidth and makes it the model most clearly aimed at professional creative workloads rather than general portable storage.

TerraMaster positions the D1 SSD Pro for 8K video editing, large project transfers, direct-edit external workflows, and users who want the fastest option in the range for a single M.2 NVMe drive. The listed performance reaches up to 7061MB/s read and 6816MB/s write when tested with a Samsung 990 Pro 4TB SSD on a Mac M4 Pro system using AJA System Test.

Although the D1 SSD Pro supports PCIe 3.0, 4.0, and 5.0 M.2 2280 NVMe SSDs up to 8TB, the specification notes a single PCIe 4.0 x4 M.2 slot. This means the enclosure can physically and logically accept a wide range of modern NVMe drives, including examples such as the Samsung 990 Pro and WD SN850X, but performance will still depend on the SSD installed, the host system, and the connection used.

It is compatible with Thunderbolt 5, Thunderbolt 4, Thunderbolt 3, USB4, and USB 3.2/3.1/3.0, so it can step down for broader system support. TerraMaster also includes a color-coded connection indicator, using white for Thunderbolt or USB4 high-speed connections and orange for USB 3.2 or lower, which helps identify when the enclosure is not running at its intended performance level.

The chassis is built around an all-aluminum dual-fin passive cooling design rather than active cooling. TerraMaster describes the cooling system as using a built-in thermal pad, 38 fins, and a full aluminum-alloy shell to help control temperatures during sustained transfers or editing workloads. The enclosure remains fanless and silent, which may matter in audio-sensitive editing rooms or recording environments.

It also includes hardware protection against short circuits, voltage surges, and electrostatic discharge, along with a supplied protective case for travel. At 300g and 121 x 58 x 37mm, it is the largest and heaviest of the 3 models, but that size is tied to the higher-speed interface and more substantial passive heatsink design.

Backupper Software for PC/Mac/Mobile

TerraMaster’s D1 SSD range is also tied into the company’s backup software ecosystem, although the specific tools vary by platform. On Windows, the main utility is TPC Backupper, a free backup and synchronization tool for personal use. It can be used to back up a full operating system, entire disks, selected partitions, individual folders, application data, settings, and Microsoft Outlook emails. It supports full, incremental, and differential backup methods, along with file synchronization and disk or partition cloning. Backup destinations can include local disks, external USB storage, network shares, NAS systems, and cloud storage, which allows it to fit into a wider 3-2-1 backup routine rather than only working with TerraMaster hardware.

For mobile use, TerraMaster refers to the TDAS App for iOS and Android, allowing users to back up photos, videos, and other phone files to the connected private drive instead of relying only on cloud storage. The D1 SSD is listed as compatible with iOS 15.6 or later and Android 11 or later for this function. The D1 SSD Plus and D1 SSD Pro are also supplied with software-led backup features in their product positioning, though the clearest desktop backup support is on Windows through TPC Backupper. TerraMaster does not present the D1 range as a replacement for a NAS-based backup system, but the combination of portable NVMe storage and simple backup utilities gives the enclosures a role in local copies, travel backups, temporary project protection, and fast restores when connected directly to a host device.

Terramaster D1 SSD vs D1 SSD PLUS vs D1 SSD PRO – Which Is Best For You?

The TerraMaster D1 SSD is the most suitable option for users who want a low-cost, compact, and physically protected NVMe enclosure rather than the fastest possible external SSD. Its USB 10Gbps interface is enough for general file transfers, local backups, document libraries, photo collections, and moving data between systems, while the IP67-rated casing and crush-resistant design give it a stronger focus on travel, outdoor use, site work, and less controlled environments. For users who mainly need durable portable storage and do not work with very large media files every day, this is the most practical model in the range.

The TerraMaster D1 SSD Plus is the better fit for users who want a noticeable performance step up without moving to the cost of the Pro model. Its USB4 40Gbps interface makes more sense for content creators, photographers, video editors, Mac mini users, and laptop owners who regularly move large files or want fast external project storage. It lacks the rugged IP67 focus of the standard D1 SSD and the 80Gbps ceiling of the Pro, but it sits in the middle as the more balanced option for users who need high-speed storage in a portable, fanless enclosure.

The TerraMaster D1 SSD Pro is the model aimed at users with the most demanding workflows and the right host hardware to support it. Its USB 80Gbps and Thunderbolt 5 class positioning makes it the obvious choice for 8K video work, very large project files, high-speed scratch storage, and users who want the fastest enclosure in the D1 family. It is also the most expensive, largest, and heaviest of the 3, so it makes the most sense when the available bandwidth can actually be used. For everyday backup or standard portable storage, the lower models are easier to justify, but for performance-led creative work, the D1 SSD Pro is the clear top-tier option.

Le truc cool avec un disque de backup, c'est quand vous arrêtez de le sortir du tiroir. Et c'est ce que permet de faire le DATO Ares Q4 (lien affilié) qui se trouve être aimanté et que je peux donc coller direct sur le côté de mon Mac Studio . Je l'ai depuis bientôt un an, et c'est devenu mon disque de Time Machine à résidence.

Il est trop mignon parce qu'il est tout petit, puisqu'il mesure 64 par 64 mm, 12 mm d'épaisseur, et 40 grammes, soit à peine plus gros qu'un bloc de petits Post-it, sauf que dedans y'a 4 To de NVMe en USB4. Les aimants sont prévus pour s'accrocher à un iPhone 15/16/17 Pro façon MagSafe, mais en pratique ils tiennent aussi nickel sur n'importe quelle machine, si vous collez le petit aimant-sticker livré avec.

Après je sais pas si coller un aimant sur un ordinateur c'est le move le plus intelligent que j'ai fait de ma vie mais je l'ai collé y'a 1 an, et ça bouge pas et j'ai aucun souci. Après c'est pas des GROS aimants non plus hein... C'est assez fin et pas très aimanté non plus. Et niveau connectique, c'est livré avec un câble USB-C rikiki de 10 cm.

Côté débits l'USB4 crache du 4000 Mo/s en lecture et 3600 Mo/s en écriture et comme c'est du natif, y'a pas de puce intermédiaire entre le NVMe et le port, donc on est max de ce qu'on peut avoir en vitesse avec ce genre de disque. Par contre, faut un port USB4 ou Thunderbolt 4/5 côté Mac, sinon ça retombe sur de l'USB 3.2 classique. C'est pas dramatique mais ça va 'achement moins vite quand même.

Et comme mon Mac Studio embarque 4 To en interne, c'est pile la taille du DATO que je dédie à ma sauvegarde Time Machine. Le sparsebundle peut donc grossir jusqu'à occuper tout le disque sans que je m'en occupe ! Et comme je ne le remplis jamais à 100%, je suis assez tranquille.

En plus de ce SSD, je fais toujours des backups sur mon NAS Synology avec Carbon Copy Cloner à côté parce que je suis parano et qu'on sait jamais...

Côté chauffe, la surprise est plutôt bonne, il reste froid / tiède même en plein transfert. Alors je suis pas sûr mais je me dis que le boîtier en alu du Mac Studio, joue peut-être un petit rôle de dissipateur thermique mais j'sais pas, peut-être pas... En tout cas, ça chauffe pas quoi.

Ce disque est compatible Mac, PC, Linux, et même iPhone Pro en USB-C comme ça si vous avez besoin de filmer de la 4K ProRes HDR direct sur un SSD plutôt que sur la mémoire interne, c'est possible ! Et il est garanti 5 ans, ce qui est toujours bon à prendre.

Voilà, si ça vous intéresse, le DATO Ares Q4 (lien affilié) est dispo sur Amazon en versions 1 To, 2 To ou 4 To .

USB4 to 2x 10GbE Adapter – Genius, or Too Little Too Late? (QNA-UC10G2T Review)

The QNAP QNA-UC10G2T is a USB 4 to dual 10GbE adapter built for systems that lack native high-speed network expansion and need dependable multi-gig connectivity through a single Type C port. It provides 2 x 10GBASE-T copper ports, supports multi-speed operation from 10Gbps down to 100Mbps, and includes full driver support for Windows 11, macOS 12.7 to 15.4, and Ubuntu 22.04. Internally it uses dedicated AQC113 controllers for each port, allowing the OS to treat the adapter as two distinct NICs and enabling features such as SMB Multi Channel for aggregated bandwidth. The enclosure is a passive full-metal heatsink that spreads thermal load through a multi stage cooling structure, which your testing confirmed remained below typical thermal expectations even during 24-hour sustained transfers. As a premium module priced significantly higher than generic USB 4 adapters, it is designed for users who require stable long-duration performance, predictable throughput, and compatibility with modern USB 4 or Thunderbolt 3 and 4 hosts rather than the improvised multi controller designs seen in low cost alternatives.

QNAP QNA-UC10G2T Review – Quick Conclusion

The QNAP QNA-UC10G2T is a premium dual-port 10GbE adapter built around USB 4, designed for users who need stable, sustained multi gigabit performance rather than the inconsistent behaviour often seen in low cost USB network adapters. Its dual AQC113 controllers provide two discrete interfaces that operate independently at full speed, which allows for reliable SMB Multi Channel operation and predictable multi stream transfers. The all metal chassis functions as a multi stage passive heatsink, keeping temperatures stable during long workloads and preventing throttling even after hours of continuous access. Performance closely matches QNAP’s published figures, with both ports maintaining high throughput when paired with capable NVMe based systems. Driver installation is required on all supported platforms, and the adapter is not currently usable when plugged directly into most NAS operating systems, which limits flexibility. The price is considerably higher than generic USB 4 network adapters, but for professionals who rely on consistent 10GbE throughput on laptops, workstations, or compact systems without PCIe expansion, the QNA-UC10G2T offers a stable, well engineered solution that prioritises long term reliability over entry level cost.

QNAP QNA-UC10G2T Review – Design & Cooling

The QNA-UC10G2T uses a solid metal chassis that functions as a structural shell and a primary thermal dissipation surface, giving it a distinctive weight and density compared with typical USB network dongles. The outer enclosure is machined with large surface area ridges that extend across the top panel, while the base remains flat to maintain direct thermal contact with the internal controllers. This physical design is not decorative but exists to distribute heat from the AQC113 chips into the enclosure walls and then outward into the surrounding airflow. Its appearance is closer to a purpose built passive heatsink than a consumer accessory, which mirrors the product’s emphasis on maintaining stability during sustained high throughput workloads.

Internally the design is organized around a single board layout that places both controllers on the lower PCB surface, pressed directly against the internal heat spreader via thermal pads and paste. This arrangement ensures that the highest heat generating components transfer their thermal output into the metal layers with minimal resistance. Above this, the chassis integrates a second stage aluminium heat spreader that covers the width of the unit, supported by an additional top panel that completes the third passive cooling stage. This layered thermal design reflects a more methodical architecture than the mixed component assemblies found in low cost USB 4 to network adapters, which commonly rely on bridging older interfaces and produce unpredictable heat patterns under load.

The fanless approach is a key design choice, giving the adapter completely silent operation during heavy transfers. In your testing, the enclosure maintained stable temperatures even after several minutes of saturation, typically remaining in the 47 to 51 degree range depending on activity and ambient levels. This thermal profile suggests that the shell’s passive system prevents hot spots and avoids the typical thermal throttling behaviour found in cheaper adapters, especially those built around multiple controllers stacked on different interconnected PCB modules. The predictable cooling also assists long term reliability for users who expect constant 10GbE connectivity during file editing, remote rendering, or multi channel transfers.

The physical I/O layout consists of a single USB 4 Type C port on one end and 2 x 10GBASE T ports on the opposite face, keeping cable paths separated to prevent mechanical strain or excess heat mingling between connectors. The RJ45 ports support Cat 6a cabling as recommended by QNAP and can operate across 10Gbps, 5Gbps, 2.5Gbps, 1Gbps, and 100Mbps speeds depending on the switch or device connected. While minimalistic, this separation aligns with the use case of the adapter as a mobile or desktop expansion tool where the position of cables may influence airflow and heat shedding around the chassis.

The cooling strategy also reflects QNAP’s intention for the adapter to be used in long-running, high-intensity environments rather than short bursts. During your extended 24 hour tests, the chassis maintained consistent thermal readings, with the USB side remaining cooler than the network interface side. The overall thermal balance avoided thermal spikes, which is essential for dual port operation where simultaneous read and write tasks across two 10GbE channels can push less optimized adapters into throttling. By spreading heat evenly across the frame, the device sustains performance in ways that improvised USB 4 adapters often fail to achieve during multi hour workloads.

QNAP QNA-UC10G2T Review – Internal Hardware and Connectivity

Inside the QNA-UC10G2T, the hardware is centred around two AQC113 controllers, each dedicated to one 10GbE port. This avoids the shared bandwidth and internal bottlenecks that occur in budget adapters that route multiple ports through a single controller or bridge older chipsets together. Each controller appears to have a direct path to the USB 4 interface, allowing the host operating system to detect two independent network interfaces. This structure is essential for features such as SMB Multi Channel, NIC bonding, and network segmentation, since it ensures that both ports operate with consistent throughput rather than competing for limited controller resources. The hardware layout intentionally avoids stacked modules or mixed technology bridges, creating a predictable and uniform architecture.

Connectivity through the USB 4 Type C interface is built to support both USB 4 and Thunderbolt 3 and 4 on most systems. QNAP includes a 1m USB 4 certified cable in the package to ensure full bandwidth without relying on third party cables that may deliver reduced link speeds. Host compatibility extends to Windows 11, macOS 12.7 to 15.4, and Ubuntu 22.04, although all require installation of the Marvell AQtion driver to enable proper operation. This software dependency reflects the adapter’s use of high performance controllers that are not handled by generic drivers. The device is not compatible with ARM based Windows systems, which limits use with some compact laptops and tablets but aligns with the adapter’s focus on fully featured desktop and workstation class hardware.

The dual 10GBASE T ports support 10Gbps, 5Gbps, 2.5Gbps, 1Gbps, and 100Mbps operation and auto negotiate based on the connected switch or device. This makes the adapter usable in mixed infrastructure where not all devices run at 10GbE rates. The reliance on RJ45 also gives it broad physical compatibility, making it suitable for direct PC to NAS connections, multi port NAS access, or integration with 10GbE switches. Your testing confirmed that the independent controllers allowed each port to reach close to saturation independently and operate simultaneously with sustained transfer rates across both links.

The internal hardware layout also supports clear network identification through the OS. When connected, the adapter exposes two discrete interfaces, each carrying its own MAC address, speed negotiation, and jumbo frame support. This allows users to create dedicated VLANs, segment traffic, or assign separate subnets without the limitations seen in single controller USB adapters that present only one interface for both ports. The device is therefore capable of acting as a genuine dual port NIC rather than a multi port breakout filtered through a single internal path. In testing, each interface responded consistently when used with tools such as iperf and CrystalDisk, confirming symmetric behaviour between both controllers.

While the adapter is designed primarily for client devices, your testing highlighted that direct USB 4 to 10GbE connectivity on NAS platforms remains limited. Most NAS operating systems lack mature USB 4 drivers or Thunderbolt over IP integration, which prevented the adapter from functioning when connected directly to TrueNAS or Unraid. This reflects current software gaps rather than a hardware limitation, and future NAS platforms with USB 4 or Thunderbolt support may unlock additional use cases. For now, the hardware is best suited to upgrading laptops, mini PCs, and workstations where USB 4 is available and supported through platform level drivers.

QNAP QNA-UC10G2T Review – Performance

In practical testing, the QNA-UC10G2T delivered sustained throughput that closely aligned with QNAP’s published figures, with both ports maintaining stable operation during long running transfers. When used with IP based benchmarking tools, each 10GbE connection reached near saturation independently, confirming that the internal controllers can deliver full bandwidth without cross interference. During concurrent testing where two separate sessions targeted different devices, both ports maintained consistent performance levels, which demonstrated the benefit of having two discrete AQC113 controllers rather than a single shared architecture that would introduce contention under load.

The adapter also showed strong results during SMB based file transfers, which typically stress both network performance and host storage. Using high speed NVMe backed devices such as the Minisforum MSS1 Max and the Asustor Flashstor Gen 2, throughput regularly approached the upper limits of a single 10GbE link and in some cases exceeded 13 to 14 Gbps combined when SMB Multi Channel was enabled. This reflected not only raw link speed but the ability of the device to maintain a stable, predictable data path without drops or thermal throttling. The performance was also consistent during repeated transfers, confirming sustained operation rather than peak only figures.

Thermal stability had a direct impact on performance, and the adapter’s multi stage passive cooling structure prevented heat buildup during heavy access. After several minutes of continuous transfer, external surface readings typically ranged from 47 to 51 degrees depending on the measurement point, with the USB interface side remaining cooler than the network side. Even after 24 hours of operation, temperatures remained within a narrow range, and throughput did not degrade. This behaviour contrasts with budget adapters built from stacked controller layers, which often throttle or lose throughput when thermals rise beyond the enclosure’s capacity to dissipate heat.

The adapter performed best when paired with systems that support jumbo frames, high performance modes, and direct NVMe based storage, since these environments can fully exploit dual 10GbE bandwidth. On platforms that lack USB 4 optimisation or rely on generic drivers, performance may vary, and your testing confirmed that most NAS operating systems were unable to recognise the adapter due to limited Thunderbolt or USB 4 networking support. For desktop and mobile clients, however, the performance remained consistent and aligned closely with QNAP’s internal lab measurements, provided that the user installed the appropriate drivers and used the supplied USB 4 certified cable.

QNAP QNA-UC10G2T Review – Verdict & Conclusion

The QNA-UC10G2T positions itself as a specialised tool for users who require reliable dual 10GbE connectivity through a single USB 4 port and are prepared to invest in a more robust architecture than the improvised solutions found in low cost adapters. Its metal chassis, multi stage passive cooling design, and independent AQC113 controllers result in predictable behaviour during long duration workloads, with sustained throughput that remains close to full 10GbE saturation on both ports. The requirement for platform specific drivers and the lack of NAS side support limits its flexibility in certain environments, yet for desktop systems, laptops, and compact workstations, the adapter provides one of the most stable USB based 10GbE implementations currently available.

Although priced well above many alternatives, the hardware and performance characteristics position it for users who prioritise reliability over entry level cost. Photographers, editors, engineers, and remote teams who depend on consistent multi gig file transfers may find the premium justified, especially when mobility or small form factor systems prevent installation of PCIe cards. For users simply seeking an inexpensive path to 10GbE, the high cost will be difficult to justify, but for those needing dependable, long term dual port connectivity in a portable form, the QNA-UC10G2T delivers a focused and technically capable solution.
