Icy Dock ExpressCage MB741V4P-B Drive Bay Adapter for 3.5" PCI Express NVMe 4.0 - U.2 (SFF-8639) Host Interface Internal - Black - Hot Swappable Bays - 1 x HDD Supported - 1 x SSD Supported - 1 x Total Bay - 1 x 2.5" Bay - 64 Gbit/s Data Transfer Rate - Metal, Acrylonitrile Butadiene Styrene (ABS)
The ExpressCage MB741V4P-B is engineered to provide enterprise-grade U.2 and U.3 NVMe SSD integration in any standard 3.5" device bay. Designed with ICY DOCK's signature ExpressTray, it offers completely tool-less SSD installation for quick drive swaps, while retaining the stability of a tray-and-screw mounting system for long-term use in demanding environments. Supporting PCIe 4.0 x4 interface with transfer speeds of up to 64Gbps (host
By utilizing a single external 3.5" bay, the MB741V4P-B maximizes space efficiency in compact systems. It is ideal for small-form-factor PCs, embedded platforms, edge computing systems, in-vehicle PCs, and enterprise workstations where internal space is limited. When paired with an onboard NVMe port or an M.2-to-U.2 adapter, the MB741V4P-B can be connected without consuming valuable PCIe expansion slots-freeing them for GPUs, networking
The ExpressTray allows users to install or remove a U.2/U.3 NVMe SSD in seconds- no tools required. Simply insert the drive into the tray, close the latch, and slide it into the enclosure. The tray supports both 7mm and 15mm U.2/U.3 SSDs, while the bay design accommodates drives ranging from 5mm to 15mm in height. This makes it an ideal solution for environments where quick drive swaps and broad SSD compatibility are essential, such as
For systems operating in high-vibration environments or for users who prefer additional mechanical stability, the tray provides optional screw mounting points to secure the SSD firmly in place. This ensures reliable operation during transportation or in industrial deployments.
An easy-access drive ejection button allows smooth tray removal without excessive force, while the front-panel LED provides instant visual feedback on drive power and activity status-helping users quickly monitor SSD operation.
