Flagship 40Gbps Mobile Storage Center Compatible with Thunderbolt 5/4/3 Ecosystems
⚠️ CRITICAL HOST INTERFACE NOTICE: The Lekuo DTB3S61 utilizes premium PCIe-tunneling technology to deliver up to 40Gbps of aggregate bandwidth. To unlock the full speed of the onboard M.2 NVMe slot (up to 32Gbps), this enclosure MUST be connected to a native USB4 or Thunderbolt 5/4/3 host port. Connecting to legacy Type-C USB 3.2, 3.1, or 3.0 ports will severely bottleneck performance and may cause the high-speed NVMe drive to not be recognized by the host OS.
The Lekuo DTB3S61 USB4 Hybrid Storage Enclosure introduces a monumental breakthrough for external, high-density storage management. Seamlessly blending lightning-fast solid-state speed with massive hard-drive backup capacities, this single premium aluminum enclosure features a unique 5-bay hybrid architecture: 1 x ultra-fast M.2 NVMe SSD slot and 4 x hot-swappable SATA III HDD/SSD bays. Powered by a high-speed 40Gbps USB4 interface, it channels comprehensive desktop-grade array speeds down to laptop and small-form-factor systems via a single cable connection.
Housed inside a rugged, structural aluminum alloy tower configured with a smart active cooling matrix, the DTB3S61 operates with absolute thermal stability under non-stop, multi-hour sequential read/write cycles, making it the ultimate local storage vault for content creators, IT professionals, and data engineers on the move.
Technical Architecture & Core Highlights
Next-Gen 5-Bay Hybrid Storage Topology
The standout structural benefit of the Lekuo DTB3S61 is its dual-tier storage arrangement. By separating workflows into specialized high-speed and high-capacity zones, it optimizes system performance natively:
- 1 x M.2 NVMe SSD Slot (Up to 32Gbps): Provides a dedicated, full-speed PCIe 3.0 x4 pipeline—perfect for real-time 4K/8K media scratching, active OS boot environments, or high-frequency caching pools.
- 4 x SATA III 6Gbps Bays (High-Capacity Storage): Accommodates up to four 3.5-inch mechanical hard drives or 2.5-inch SATA SSDs, creating a massive local archive tier for cold-data storage, automated system backups, and media pooling.
Intelligent 40Gbps Shared Bandwidth Allocation
Equipped with a native USB4 controller logic, all internal storage nodes dynamically share the massive 40Gbps bus. While the NVMe tier runs on low-latency PCIe paths tapping into full-speed execution, the SATA multi-drive infrastructure utilizes an efficient downstream USB 10Gbps-to-SATA controller chip. This dual-engine layout ensures concurrent multi-drive data sharing remains smooth and buffer-free.
Daisy-Chain Expansion & Built-In Power Infrastructure
- High-Speed Downstream Expansion Port: Features a secondary dedicated high-speed expansion output port, supporting daisy-chain setups for adding secondary 40Gbps peripherals, premium displays, or high-speed capture hardware to your master terminal link.
- Heavy-Duty DC 12V/10A Power Supply: Packed with an independent 120W power brick to guarantee that four high-capacity, high-draw 3.5" enterprise mechanical drives can spin up concurrently with zero hardware voltage drops.

Target Vertical Use Cases & Workflow Execution
1. Professional Video Post-Production & DIT On-Site Ingesting
Film editors, colorists, and digital imaging technicians (DITs) require blazing-fast local scratch speeds to process raw multi-camera footages alongside immediate, high-capacity redundant storage to secure source assets.
- Engineering Value: The Lekuo DTB3S61 allows crews to slot an off-the-shelf NVMe SSD as their primary 32Gbps ingestion drive to edit uncompressed RAW timelines seamlessly. Concurrently, the four 3.5" SATA bays serve as a massive local archive pool, copying and backing up project media silently behind the scenes.
2. Compact Workstation Upgrades & Home Lab Storage Pools
Mini-PCs, Mac Studio devices, and compact server nodes often run out of internal storage slots quickly. Setting up external network attached storage (NAS) can introduce network routing latencies and high hardware deployment overhead.
- Engineering Value: Acting as a high-bandwidth local micro-DAS, this enclosure hooks directly into a host system's USB4 pipeline. It opens up massive hybrid expansion potential without requiring complicated network setups or taking up valuable desk space (only 238.5mm length).
Executive Summary
The Lekuo DTB3S61 USB4/Thunderbolt Hybrid Storage Enclosure redefines external data management. Incorporating an elite 5-bay hybrid storage arrangement (1x NVMe M.2 SSD + 4x SATA HDD) into a premium aluminum alloy chassis (238.5 x 125 x 142mm), it creates a blistering 40Gbps shared storage pipeline exclusively over high-speed USB4 and Thunderbolt 5/4/3 links. Blending built-in daisy-chain versatility, native hot-swap capabilities, and a powerful 120W power system, the DTB3S61 stands out as the ultimate multi-tier storage solution for high-throughput professional applications.
