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

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

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

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

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

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

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

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.

Plutôt que d'attaquer une cible frontalement, certains groupes de hackers optent pour une approche redoutable : contaminer les sites que la victime va visiter. Une technique discrète, patiente et efficace contre les cibles les plus protégées, et qui pourrait prendre un relief nouveau à l'heure des agents IA.

Dans un article publié le 10 avril 2026 sur le site américain Ars Technica, un père de famille raconte comment le piratage du compte Discord de sa fille a mis en lumière les failles structurelles de l’application de messagerie.

Le 11 avril 2026, OpenAI a déployé une mise à jour obligatoire de ses applications macOS, après la découverte d’une faille dans la bibliothèque Axios, compromise fin mars. L’entreprise assure n’avoir constaté aucune intrusion, mais agit par précaution.

Microsoft a récemment annoncé vouloir améliorer en profondeur le design de Windows 11, avec un focus particulier sur l’application Paramètres, censée remplacer définitivement le Panneau de configuration.

Mais en parallèle, l’entreprise reconnaît qu’elle ne peut toujours pas supprimer cet outil historique, pourtant vieux de près de 40 ans.

Une priorité assumée : rendre Windows 11 plus cohérent

Microsoft indique vouloir corriger l’un des problèmes les plus visibles de Windows 11 : le manque de cohérence entre ses différentes interfaces.

L’objectif est de moderniser progressivement le système en améliorant :

• l’application Paramètres
• le mode sombre
• certaines pages système
• l’accessibilité et les interactions

Cette refonte vise à unifier l’expérience utilisateur et à réduire les incohérences entre anciennes et nouvelles interfaces.

Les Paramètres au cœur de la transition

Depuis Windows 8, Microsoft tente de remplacer le Panneau de configuration par l’application Paramètres.

Cette dernière devient progressivement l’interface principale pour :

• configurer Windows
• gérer les comptes
• contrôler les périphériques
• accéder aux options système

Mais malgré plus de 10 ans d’évolution, la transition reste incomplète.

Pourquoi Microsoft ne peut toujours pas supprimer le Panneau de configuration

Microsoft a récemment expliqué pourquoi le Panneau de configuration est toujours présent dans Windows 11.

Le problème principal vient de l’héritage technique de Windows.

Le système doit encore prendre en charge :

• des pilotes anciens
• des périphériques legacy (imprimantes, réseau, etc.)
• des outils avancés comme le gestionnaire de périphériques

Supprimer brutalement le Panneau de configuration risquerait de casser une grande partie de ces fonctionnalités.

Microsoft confirme donc adopter une approche progressive :

• migration des fonctionnalités une par une
• maintien de la compatibilité avec l’existant
• tests pour éviter toute régression

Comme l’explique Microsoft, l’entreprise avance prudemment afin d’éviter toute incompatibilité avec le matériel et les pilotes existants.

Certaines fonctions dépendent encore du Panneau de configuration

Aujourd’hui encore, certaines actions redirigent vers le Panneau de configuration :

• ajout manuel d’imprimantes
• paramètres réseau avancés
• gestion détaillée des périphériques
• outils système historiques

Ces fonctionnalités ne sont pas encore totalement migrées dans Paramètres, notamment parce qu’elles nécessitent un niveau de contrôle avancé difficile à reproduire dans une interface simplifiée.

Un héritage qui ralentit l’évolution de Windows

Contrairement à d’autres systèmes comme macOS, Microsoft continue de supporter un très large éventail de matériels anciens.

C’est à la fois :

• une force (compatibilité exceptionnelle)
• et une contrainte (évolution plus lente)

Chaque changement doit être testé sur un grand nombre de configurations, ce qui ralentit considérablement la transition vers une interface moderne.

Une transition lente… mais inévitable

Malgré ces difficultés, Microsoft continue de migrer progressivement les fonctionnalités vers l’application Paramètres.

Certaines options ont déjà été déplacées ces dernières années, et d’autres devraient suivre.

Mais l’entreprise ne donne aucun calendrier précis pour la disparition complète du Panneau de configuration.

Conclusion

Microsoft accélère enfin ses efforts pour améliorer le design de Windows 11 et rendre l’expérience plus cohérente.
Cependant, la disparition du Panneau de configuration reste un chantier complexe.

Entre modernisation de l’interface et compatibilité avec des décennies de matériel et de logiciels, Microsoft doit avancer avec prudence.

Cette situation illustre parfaitement la difficulté pour Microsoft de moderniser Windows tout en conservant une compatibilité exceptionnelle avec l’existant.

Le Panneau de configuration n’a donc pas encore dit son dernier mot — même en 2026.
