LeKuo DTB3S61: USB4 40Gbps 5-Bay Hybrid Hard Drive Enclosure—A High-Speed, High-Capacity All-in-One Storage Expansion Solution

USB4 40Gbps Dual-Port + 5-Bay Hybrid Hard Drive Enclosure: Redefining the External Storage Experience

Conventional multi-bay hard drive enclosures typically feature a single USB port and a pure SATA architecture, resulting in either insufficient speed or inadequate capacity; high-speed drive enclosures, on the other hand, are limited to a single bay, failing to meet the needs of multi-drive backup and expansion.

The LeKuo DTB3S61 centers on a USB4 40Gbps controller, dual 40Gbps Type-C ports, and a hybrid bay architecture to address the three major challenges of speed, capacity, and expandability at the hardware level:

1. 40Gbps Ultra-Wide Bus

Equipped with a professional USB4 40Gbps high-speed chipset, it offers full compatibility with Thunderbolt 3/4/5 and USB4 interfaces, providing a full-speed channel for NVMe SSDs and completely eliminating external storage bottlenecks.

2. Dual Type-C Intelligent Division of Labor

One upstream port connects to the host, while one downstream port expands high-speed peripherals (network cards, docking stations, etc.). All devices share the 40Gbps total bandwidth, resulting in a cleaner desktop setup.

3. 1+4 Hybrid Drive Bay Design

1× M.2 NVMe (PCIe 3.0 x4) + 4× SATA 3.0 (supports 3.5/2.5-inch HDDs/SSDs)

High-Speed, Stable, and Compatible Core Performance

1. Intelligent Bandwidth Allocation: High Speed and Large Capacity Without Compromise

● NVMe Channel: Dedicated PCIe 3.0 x4 + 40Gbps bus, delivering full-speed NVMe SSD performance

● SATA Channel: Stable multi-drive operation without speed drops

● Total Capacity: Supports up to 128TB; single mechanical hard drives can reach 20TB+, while NVMe SSDs support up to 8TB—store massive amounts of media with ease.

2. Dual 40Gbps Type-C Ports for Maximum Expansion Capabilities

● Upstream Port: USB4 ×1 (40Gbps, supports PD charging protocol)

● Downstream Port: High-speed expansion port ×1 (for peripheral expansion)

3. Intelligent Temperature Control Cooling for 24/7 Stable Operation

● Cooling Solution: Combines passive cooling via an all-aluminum alloy chassis with active cooling via an intelligent, temperature-controlled silent fan

● Fan Logic: Automatically adjusts fan speed based on drive temperature—silent operation under low load and powerful cooling under high load to prevent thermal throttling or drive failure

4. Full-featured, user-friendly design for zero-threshold setup

● Drive Compatibility: Supports 2.5/3.5-inch SATA HDDs/SSDs and M.2 NVMe SSDs; quick drive replacement without opening the enclosure

● System Compatibility: Windows 10/11, macOS, Linux (Kernel 5.4+)

● Visual Status Indication: LED indicators display real-time read/write and error statuses, providing clear visibility into device operation.

One-Stop High-Performance Storage Solution for Multiple Fields

1. Video Editing / 3D Rendering / Audio Production

4K/8K footage, project files, and rendering caches demand both high storage speed and capacity:

● Solution Value: Use NVMe SSDs for high-speed caching and project files, while SATA HDDs store raw footage and archived files

● Performance: 40Gbps high-speed interface opens large files instantly, enabling multi-track editing and real-time previews without lag, while significantly boosting rendering and output efficiency.

2. Local AI Training and Inference

 

AI model training requires frequent read/write operations on massive datasets, making low-latency, high-speed storage critical:

● Solution Benefits: NVMe drives host training datasets and model weights, while SATA drives store backup data, enabling tiered management of hot and cold data

● Actual Performance: Reduces data read latency, improves model training and inference efficiency, and meets the high-speed storage demands of local AI R&D.

3. Small Studio/Personal Creative Storage Pool

 

Multi-user collaboration and multi-device sharing require a unified, high-speed storage hub:

● Solution Value: A single hard drive enclosure meets the team’s needs for media storage, backup, and high-speed access, with USB4/Thunderbolt interfaces compatible with Mac and Windows devices

● Actual Performance: Simultaneous access by multiple users, centralized media management, and significantly improved collaboration efficiency.

4. High-Speed Expansion for Mini PCs/Laptops

 

ITX mini PCs and ultrabooks have limited ports and insufficient drive bays, making it impossible to install multiple hard drives:

● Solution Value: Expand to 5 hard drives at once, balancing high speed with large capacity

● Practical Application: Build a mobile workstation + massive storage combination, suitable for all scenarios including on-location shooting and on-site editing.

Summary

The LeKuo DTB3S61 Type-C 40Gbps 5-bay hybrid hard drive enclosure completely resolves common pain points associated with external storage, such as the trade-off between speed and capacity, limited expandability, and poor heat dissipation. Combining four key advantages—40Gbps ultra-high speed, up to 128TB of massive capacity, intelligent temperature-controlled cooling, and excellent compatibility—this product serves as a one-stop, high-performance storage solution for video production, AI training, data backup, studio storage, and mini-PC expansion, setting a new standard for high-speed, high-capacity external storage.
