New Cost-Effective USB4, M.2 and PCIe Adapters from IOCREST/Lekuo for 2026 Revealed

IOCREST, also marketed under the Lekuo name for consumer channels, is preparing a broader range of USB4, M.2, and PCIe expansion products aimed at users who need higher speed networking, storage expansion, or more flexible external PCIe connectivity. Based on the product information provided and the accompanying interview material, the current lineup combines shipping devices with several products still in development or not yet formally listed on the company’s official product pages, reflecting a portfolio that spans compact 10GbE adapters, SFP+ connectivity, multi-drive enclosures, and USB4 based PCIe breakout designs.

Lekuo USB4 to 10GbE Hub

Buy HERE on Amazon – Buy HERE on AliExpress

The Lekuo DTB3R61 is a compact USB4 hub that combines 10GbE networking with basic peripheral and removable media expansion in a single enclosure. It is built around a USB4 upstream connection and is intended for hosts that support USB4 or Thunderbolt 3/4/5, rather than older USB 3.x only systems. In practical terms, this positions it as a multi function dock for users who need wired 10GbE, a small number of USB ports, and SD or TF card access without moving to a larger desktop class dock.

The port layout is relatively simple, consisting of 1x 10GbE RJ45 port, 3x 5Gbps USB Type A ports, and a TF/SD 3.0 card reader. The supplied specifications list a 40Gbps host link, support for Windows, macOS, and Linux, and a compact metal chassis. Although your transcript refers to a fanless design, the specification sheet provided here states an aluminum alloy casing with fan assisted cooling, so that distinction should be treated carefully in the article unless you want to frame it as pre release versus final spec variation.

Lekuo USB4 to 2x25GbE Adapter

Buy HERE on Amazon – Buy HERE on AliExpress

This unreleased Lekuo adapter is one of the more bandwidth focused products discussed in the interview material, built around a USB4 host connection and 2x 25GbE network ports. Based on the information provided, the design uses an SFP based approach rather than RJ45, which is consistent with the higher thermal and signal demands of 25GbE. It is positioned as a compact external network adapter for systems that need significantly more throughput than 10GbE, while still relying on USB4 as the host side connection.

The transcript also indicates several design details that help distinguish this unit from more common USB or Thunderbolt network adapters. It is described as a silent design with no active fan, includes an external barrel power input, and features a physical power button on the enclosure. The company indicated that the product was expected around Q2 and priced below $200 at the time of filming, but as it is not yet listed on the official product page, those details should be treated as pre release guidance rather than final retail specification.

Lekuo DTB3F21 USB4 to 2x10GbE Adapter

Buy HERE on Amazon – Buy HERE on AliExpress

The Lekuo DTB3F21 is a dual port USB4 network adapter designed around 2x 10GbE SFP+ connections. Unlike simpler USB to Ethernet devices that target single port RJ45 connectivity, this model is positioned for users who need higher density fibre or DAC based networking from a single external enclosure. The supplied specifications identify the Intel 82599 controller, placing it closer to a traditional server class 10GbE design than a lower cost USB NIC.

From the product information and transcript, this adapter is part of Lekuo’s broader push into USB4 based external networking, especially for systems that lack internal expansion but still need multi port high speed network access. The enclosure is described as compact and externally connected over USB Type C, with support across Windows, Windows Server, Linux distributions, and several enterprise networking features such as VLAN support, jumbo frames, interrupt moderation, and virtual machine queue support. In the transcript, a dual 10GbE version is also discussed alongside the dual 25GbE model as part of the same general product family.

Lekuo M.2 to 10G SFP+ Adapter

Buy HERE on Amazon – Buy HERE on AliExpress

Lekuo is also developing an M.2 to 10G SFP+ adapter, extending the same general idea seen in its M.2 to 10GbE RJ45 products toward fibre based networking. In the transcript, this product is described as a refined version of an existing concept rather than a completely new direction, aimed at compact systems that only have an M.2 slot available for expansion. That makes it relevant for small servers, mini PCs, and embedded platforms where a full PCIe slot is not available but higher speed network connectivity is still required.

The main distinction here is the move from copper 10GbE to SFP+, which allows use of fibre modules or DAC cabling depending on deployment requirements. That gives the adapter a different role from the RJ45 version, particularly in longer distance links or environments already using SFP+ switching infrastructure. Based on your notes, this product is not yet available on the official product page, so the current information is limited to what was shown and discussed during the visit rather than a finalized retail specification sheet.

Lekuo USB4 to 2x PCIe Gen4 x1 Slots Box

Buy HERE on Amazon – Buy HERE on AliExpress

This unreleased Lekuo USB4 expansion box is designed to expose 2x PCIe slots from a single external USB4 connection, using the same basic enclosure approach shown on the company’s 8x 1GbE adapter. In the transcript, the unit is described as a small PCIe dock originally used internally for testing, with the USB4 connection bridging to 2 separate PCIe paths inside the enclosure. The concept is straightforward: rather than delivering fixed networking or storage, it provides a more flexible external PCIe breakout for users who want to install their own cards.

That flexibility is the main point of interest here. The transcript suggests use cases such as network cards, SATA cards, and other compact PCIe devices, with bus power available over USB4 and a barrel power input included for cards that need more power than the host connection can provide on its own. Since this product is not yet listed on the official product page, the available information is still limited and some details remain unconfirmed. The requested naming of this section as a PCIe Gen4 x1 slot box reflects the intended lane configuration you provided, but that specific wording was not fully documented in the supplied official specification text, so it should be treated as based on your product notes.

Lekuo USB4 to 4 HDD and 1x Gen4 M.2 Box

Buy HERE on Amazon – Buy HERE on AliExpress

Lekuo is also preparing a multi drive USB4 enclosure that combines 4 HDD bays with a single PCIe Gen4 M.2 NVMe slot in the same chassis. Based on the transcript, this is a DAS rather than a NAS, so it is intended to provide direct attached storage expansion over USB4 instead of functioning as a self contained network appliance. The inclusion of the M.2 slot adds a layer of flexibility beyond a standard 4 bay enclosure, allowing for SSD caching, a dedicated fast volume, or a separate high speed workspace alongside the hard drive array.

The product is described as relying on software RAID rather than including a hardware RAID controller, and the transcript also notes a dual port TB4 style design for daisy chaining. At the same time, the core concept is clear: this is an external storage enclosure aimed at users who want a mix of larger capacity HDD storage and faster NVMe storage within a single USB4 connected device. As with several of the other products shown during the visit, this unit does not yet appear on the official product page, so the available details should be treated as pre release rather than final retail specifications.

Lekuo USB Expansion PCIe Card

Buy HERE on Amazon – Buy HERE on AliExpress

Lekuo is also developing a PCIe expansion card that combines USB and storage connectivity on a single board, aimed at systems where slot space is limited and adding multiple separate controller cards is not practical. In the transcript, the card is shown with 2x USB Type C ports, 1x USB Type A port, 4x SATA ports, and an integrated 2.5GbE network connection. Rather than focusing on a single function, it is intended as a compact multi purpose expansion card for small form factor systems, embedded builds, or storage focused PCs that still need additional external connectivity.

The card is described as operating over a PCIe Gen4 x1 connection, giving it a total host side bandwidth of 20Gbps to allocate across its various controllers. That does not mean every port can run at maximum speed simultaneously, but it does make the board suitable for mixed duty use where SATA connectivity, modest USB expansion, and basic 2.5GbE networking need to be consolidated into one slot. Based on the material you provided, this product was shown during the visit rather than backed by a full standalone specification sheet, so some lower level details remain unspecified.

Lekuo USB4 to 10G SFP+ Adapter

Buy HERE on Amazon – Buy HERE on AliExpress

Lekuo is also expanding its external 10GbE range with a USB4 to 10G SFP+ adapter, offering an alternative to the more common RJ45 based 10GbE designs already associated with the brand. In the transcript, this model is presented as a silent SFP based version of the company’s existing copper 10GbE adapter, intended for users who want fibre or DAC connectivity instead of 10GBASE T. That makes it more relevant for rackmount environments, structured fibre deployments, and users already working with SFP+ switching infrastructure.

The product appears to share the same broader design language as the other newer USB4 network adapters shown during the visit, including a compact metal enclosure, ventilation at each end, and an external power option. The transcript also notes a physical power button on this family of devices, which is relatively uncommon on compact external network adapters. As this specific single port USB4 to 10G SFP+ model is not included in the supplied formal product specification sheets, the current information is based on what was shown and described in the video rather than a final retail listing.

Who Are IOCREST/Lekuo?

IOCREST and Lekuo are effectively 2 market facing identities used by the same company. Based on the interview material, the business was founded in 2000 and has operated for more than 20 years in adapter, connectivity, and expansion hardware design. IOCREST appears more closely associated with the company’s long standing OEM and B2B activity, while Lekuo is the branding now being pushed more directly toward end users and consumer retail channels.

A key point from the interview is that the company states that most of its products are designed in house, including the internal engineering and development work behind its USB, USB4, M.2, and PCIe based solutions. It also describes its product planning as being driven by practical gaps in the market, particularly in compact systems where users need to add networking, storage, or expansion features that are not available on the base hardware. That helps explain why many of its products focus on niche but increasingly relevant use cases such as M.2 to 10GbE, USB4 to multi port networking, and external PCIe breakout designs.

The other defining part of the company’s position is that much of its historical business has been behind the scenes. In the interview, Lekuo states that before its more recent consumer push, most of its sales were B2B, with products often sold through partners, distributors, or other companies without prominent IOCREST or Lekuo branding on the product listing itself. The current shift appears to be less about changing what it makes and more about putting its own name in front of products that were previously sold in a more anonymous OEM style model.

How Good is the Terramaster TOS 6 NAS Software?

TerraMaster’s TOS 6 represents the company’s most comprehensive evolution of its NAS operating system, delivering an interface and architecture that is redesigned both visually and structurally. Replacing the earlier TOS 5, it builds on user feedback from the last three hardware generations and now arrives preinstalled on systems such as the F4-425 Plus, F2-425, and F6-424, as well as the all-flash F8 SSD Plus. The system adopts the Linux Kernel 6.1 LTS, which improves memory handling, file system performance, and hardware compatibility across newer Intel and AMD processors. With over forty new functions and more than three hundred individual refinements, TOS 6 is positioned as a more capable and robust platform for modern data storage and multi-user environments. TerraMaster’s objective with this version is to combine an accessible setup process with enterprise-style administration tools, allowing users to deploy features such as ACL permissions, SMB multichannel, Hyper-Lock WORM protection, and advanced RAID management within a simplified interface. Although still developing its ecosystem when compared with long-established NAS vendors, TOS 6 signals a step toward bridging the gap between budget and professional-grade systems.

Terramaster TOS 6 – Design, GUI and UX

TOS 6 introduces a significantly redesigned interface that emphasizes simplicity and consistency while retaining the technical depth expected from a NAS management platform. The desktop layout has been decluttered, removing excess icons in favor of a single navigation bar that centralizes access to applications, settings, and the new “Start” shortcut menu. This layout, combined with subtle animation effects and theme customization options such as Night Mode and accent color selection, is intended to make the environment less visually overwhelming than previous releases. While the interface feels smoother and more responsive, some users may still find it utilitarian compared to the polished design language of DSM or QTS. Nevertheless, the decision to reduce visual clutter and allow personalized dashboards marks a meaningful progression toward a more user-centric control experience.

The control panel, which is the backbone of the system’s configuration layer, has undergone extensive structural improvement. It now allows users to jump between related settings without closing the current menu, effectively halving the time required to perform complex administrative tasks. The inclusion of a keyword search bar further simplifies access to hundreds of configuration options ranging from network tuning to caching policies. Real-time monitoring panels, including the resource manager and storage manager, remain integrated into the main interface, but TOS 6 refines them with more accurate live updates and adjustable widgets.

This customization extends to the new system dashboard, where users can drag and rearrange data modules to match their monitoring preferences. Despite these improvements, the GUI still presents a text-heavy design, particularly in areas dealing with drive management, which could be challenging for newcomers.

The user experience, while substantially enhanced, continues to cater more toward technically proficient users than beginners. Nearly every system element is accessible from the web interface, with contextual right-click menus providing file and folder actions similar to desktop OS environments. This native browser-based functionality eliminates the need for third-party explorers for most operations and allows complete administrative control without client software. However, the interface’s dense arrangement of settings can still appear intimidating for users expecting guided wizards or visualized workflows.

TerraMaster’s focus on efficiency and configurability, rather than aesthetic guidance, reflects a deliberate design choice favoring control and transparency. For experienced users, this approach offers depth and predictability, but it remains less forgiving to casual or first-time NAS owners.

Terramaster TOS 6 – Storage Services and File Services

Storage management within TOS 6 has evolved into a far more granular and flexible system. The platform supports both traditional RAID configurations and TerraMaster’s adaptive TRAID and TRAID+ systems, which allow mixed-capacity drives to be combined while retaining redundancy across one or two disks. This feature makes expansion and migration easier, particularly for users gradually upgrading storage capacity. RAID rebuilding efficiency has also improved through “fast repair,” a mechanism that prioritizes only data-occupied sectors rather than empty disk space, substantially reducing recovery times after drive replacement. The system now separates the operating system from storage volumes entirely, allowing users to install the OS on one or two designated drives, typically SSDs, to improve response speed and cache access performance. This separation not only increases system responsiveness but also helps to protect data pools from corruption caused by OS-level failures.

The volume creation process is more flexible than in previous iterations, supporting both Btrfs and EXT4 file systems alongside iSCSI targets for raw block-level storage. Btrfs, in particular, benefits from the Linux 6.1 kernel’s improved memory handling and snapshot reliability. The inclusion of Hyper-Lock WORM (Write Once, Read Many) in both Compliance and Enterprise modes offers organizations the ability to lock data for specific periods or indefinitely, preventing modification or deletion to meet audit or regulatory requirements.

Volume-level encryption can be enabled during creation, giving administrators the option to protect sensitive data without affecting system-level performance. The management interface also displays real-time disk health data and S.M.A.R.T. metrics, alerting users to failing drives through the Message Center and email notifications, minimizing downtime and data loss risks.

TOS 6’s file service layer emphasizes both accessibility and speed. SMB multichannel support, combined with link aggregation, allows the operating system to utilize multiple Ethernet ports simultaneously to multiply throughput on supported models, improving large file transfer rates in multi-user environments. Shared folder management includes advanced ACL permissions, extending beyond traditional read/write rules to thirteen distinct access types, providing fine-grained control for business use.

Native support for protocols such as SMB, AFP, NFS, FTP, and WebDAV ensures compatibility with Windows, macOS, and Linux systems, while local mounting enables users to attach external drives or even cloud-mapped directories that synchronize automatically. File management within the web interface now features a tab-based navigation system, a first among NAS platforms, enabling quick copy and move operations without opening multiple windows, reinforcing TerraMaster’s focus on operational efficiency.

Terramaster TOS 6 – Backups and Synchronisation

Backup management in TOS 6 consolidates all related tools into a single unified interface accessible from the desktop or the control panel. This centralized hub simplifies navigation between local, remote, and cloud-based backup options while maintaining compatibility with third-party systems. The platform supports Rsync for cross-NAS synchronization, Time Machine for macOS clients, and TerraMaster’s own Centralized Backup utility for deploying and scheduling protection across multiple TNAS and remote servers. Administrators can configure recurring snapshot tasks on individual volumes or shared folders, define retention policies, and even lock snapshots to prevent deletion within a specified period. While these snapshots are not substitutes for full backups, they provide a lightweight recovery mechanism that minimizes data loss in cases of user error or ransomware infection.

Local backup utilities have been expanded to support directory-level duplication, USB external drives, and iSCSI targets. This enables administrators to replicate data within the same device, between drives, or toward another NAS through the internal network. Although backing up within a single system cannot substitute true redundancy, it offers additional flexibility for temporary mirroring or fast internal restores. For users operating hybrid environments, TOS 6 integrates with major cloud providers using its CloudSync feature, which allows continuous bidirectional synchronization between TNAS and services such as Google Drive, Dropbox, OneDrive, and WebDAV storage. Mounted cloud directories appear as native local folders, simplifying file interaction and ensuring that any modifications are reflected remotely. The mounting mechanism also allows automatic synchronization of remote data without external applications, further streamlining multi-location workflows.

In terms of automation and security, backup tasks in TOS 6 can be scheduled to run incrementally or in real time, minimizing bandwidth usage and system load. Each task includes verification and logging, with the ability to send alerts on failure through the Message Center or by email. The inclusion of Hyper-Lock WORM at the backup level ensures archived backups cannot be altered for a defined compliance period, an important feature for business environments managing regulated data. Despite the lack of the same polish found in Synology’s Active Backup or QNAP’s Hybrid Backup Sync, TerraMaster’s solution achieves a comparable range of features for small-scale and mid-tier operations. The combination of flexible snapshot scheduling, cloud integration, and data-integrity verification makes TOS 6 a notable step forward from earlier releases and closes much of the functionality gap that existed between TerraMaster and its larger competitors.

Terramaster TOS 6 – Applications, Client Tools and Services

The application ecosystem in TOS 6 has expanded both in variety and integration depth, blending TerraMaster’s own utilities with third-party and open-source solutions. The App Center serves as the central hub for installing, updating, and managing applications, ranging from productivity tools and cloud clients to virtualization and multimedia services. Many of these applications are developed in-house, such as the Centralized Backup, File Manager, and Photo Gallery utilities, while others leverage established third-party frameworks like VirtualBox for virtualization and Portainer for container management. Users can deploy Docker containers directly from the interface or access the full registry for advanced workloads, making it possible to host additional media servers, AI indexing tools, or web applications. Although the ecosystem remains smaller than Synology’s Package Center or QNAP’s App Center, the available selection covers nearly all core NAS functions that general users and small business environments would require.

Client connectivity is also a strong component of the system’s service design. The TerraMaster desktop client for Windows and macOS allows users to discover NAS systems on the network, manage synchronized folders, and create automated transfer tasks. This complements the browser-based interface by offering a faster method for initiating replication jobs or file transfers between devices. Mobile applications are available for remote access, providing basic file management and media browsing functionality, though they remain limited compared to the desktop experience. One notable improvement in TOS 6 is the ability to download client tools directly from within the App Center rather than navigating to external links, streamlining deployment and maintaining version consistency across environments.#

In the area of multimedia and AI-driven services, TerraMaster has continued to refine its photo and video indexing utilities. The AI Photo Recognition tool, embedded within the Photo Gallery application, performs facial and object detection to organize content by identity or category. It uses metadata and machine learning libraries to recognize patterns across uploaded images, enabling faster search and auto-tagging capabilities. Video and photo thumbnails can be displayed directly within File Manager, which now supports large or small thumbnail scaling depending on user preference. For users requiring broader streaming capabilities, the system includes native support for Plex and Jellyfin through the App Center, allowing local or remote playback using widely adopted external platforms rather than proprietary ones. HDMI output remains inactive on TerraMaster NAS units, so these integrations rely solely on network streaming protocols.

System maintenance and troubleshooting services have also received attention in TOS 6. The platform’s security advisor can perform automated vulnerability checks, flagging weak passwords, exposed ports, or outdated configurations. Isolation Mode remains one of its more practical safety features, instantly disconnecting all non-administrative users and disabling PHP-based third-party apps to prevent intrusion. When users encounter system errors, they can utilize the integrated issue reporting tool, which generates diagnostic logs and can enable temporary remote support for TerraMaster engineers through an authentication key.

Although this feature should be used sparingly, it represents a more direct support pathway than previous versions. Taken together, these improvements show a gradual shift in TOS 6 toward professionalization, improving reliability and ease of management while still allowing extensive customization for experienced administrators.

Conclusion and Verdict

TOS 6 demonstrates that TerraMaster’s NAS platform has matured into a far more capable and structured ecosystem. The software now integrates a wide range of features that were once missing or underdeveloped, from advanced storage management and ACL permissions to cloud synchronization and AI-driven media tools. The interface redesign brings a measurable improvement in usability, and the decision to rebuild the system on the Linux Kernel 6.1 LTS ensures better hardware compatibility and long-term stability. However, it remains evident that the user experience still leans toward a more technical audience, with complex menus and limited guidance compared to the automated workflows found on Synology DSM or QNAP QTS. The system performs reliably, but its presentation and documentation could still benefit from refinement to fully appeal to non-specialist users.

Overall, TOS 6 is TerraMaster’s most complete and confident release to date, delivering a noticeable leap in speed, data protection, and operational consistency across the company’s NAS lineup. It now offers enough depth for small businesses, IT enthusiasts, and hybrid work setups while remaining open to third-party operating systems for those seeking additional flexibility. The platform still trails behind the larger ecosystems in app diversity and cloud integration polish, yet the progress made in this generation positions TerraMaster as one of the more serious alternatives in the mid-range NAS market. For users who value functionality and system control over visual refinement, TOS 6 provides a stable and expandable foundation that indicates TerraMaster is steadily closing the gap with its more established competitors.
