Adapter card icy dock MB305M4P-B — 1× M.2 NVMe to PCIe 4.0 x4 with removable tray

The icy dock MB305M4P-B adapter card enables installation of a single M.2 NVMe SSD into a PCIe 4.0 x4 expansion slot. Designed for desktops and workstations that lack a native M.2 slot, the card accepts M.2 NVMe drives and exposes PCIe 4.0 bandwidth for high-performance storage. A removable tray provides tool-free insertion and secure mounting of the drive, simplifying upgrades, testing, or replacement without disassembling the host system.

Advantages

The adapter card provides PCIe 4.0 x4 connectivity to unlock higher sequential throughput and lower latency of modern NVMe SSDs when the host platform supports PCIe 4.0. The removable tray design streamlines drive handling, allowing quick swap-in and swap-out operations and reducing maintenance time. The low-profile bracket and compact PCB make the card suitable for a range of chassis types while maintaining a stable electrical connection and physical retention for the installed M.2 module.

Suitable for

• Upgrading a desktop or workstation with an M.2 NVMe SSD when no motherboard M.2 slot is available
• Adding a high-speed NVMe drive to systems limited to PCIe expansion slots
• Drive testing, benchmarking, or data migration workflows that require frequent SSD swapping
• Compact or low-profile PC builds where a small adapter with removable tray is preferred

Key specifications

• Interface: PCIe 4.0 x4 host connection
• Drive supported: single M.2 NVMe SSD (M key, 2242/2260/2280 compatible depending on mounting options)
• Form factor: low-profile expansion card with removable M.2 tray
• Mounting: removable tray for tool-free drive insertion and secure retention
• Compatibility: standard PCIe x4/x8/x16 slots (PCIe 4.0 capable when available)

How to use

Power off the computer and unplug it before installation. Insert the adapter into an available PCIe x4/x8/x16 slot and secure the bracket to the chassis. Remove the tray from the adapter, place the M.2 NVMe SSD into the tray at the correct M-key orientation, and secure it according to the tray’s mounting point. Reinsert the tray into the adapter until it locks in place. Reconnect power and boot the system; the operating system and firmware should detect the NVMe drive. If required, initialize and format the drive in the OS disk management utility or configure it in the system BIOS/UEFI for boot or data use.

Usage recommendations

For best performance, install the adapter in a PCIe 4.0-capable slot on a motherboard and pair it with an M.2 NVMe SSD that supports PCIe 4.0. Ensure adequate airflow around the drive area to manage operating temperatures during sustained workloads, and verify system BIOS/UEFI settings for NVMe and PCIe lane configurations before relying on the card for booting or intensive storage tasks.
