General Information

4 Bay 15mm U.2/U.3 SSD Mobile Rack for 5.25" Drive Bay - Tool-Less SSD Mounting System (2 x SlimSAS 8i SFF-8654)

Enterprise-Grade Tool-less Tray Design Meets PCIe 4.0 Speed

The ICY DOCK ExpressCage MB324V4P-B is a high-performance mobile rack designed to house up to four PCIe 4.0 U.2/U.3 NVMe SSDs (up to 15mm height) within a single external 5.25" optical drive bay. Building on the ExpressCage series' renowned tool-less SSD mounting system, the MB324V4P-B combines fast drive swaps, secure SSD retention, and optional screw-lock support into one robust design. Unlike most tool-less systems that sacrifice mounting stability, ExpressCage's removable tray design with additional screw holes delivers both hot-swappable convenience and reliable SSD retention, earning trust from enterprise storage builders and performance enthusiasts alike.

Now upgraded for PCIe 4.0 bandwidth up to 64Gbps per SSD, dual 40mm cooling fans, and SlimSAS connectivity, the MB324V4P-B becomes a compelling next-gen storage platform for system integrators, edge computing deployments, AI workstations, and high-speed NVMe RAID builds.

High-Density NVMe Expansion in Any 5.25" Optical Drive Bay

The MB324V4P-B maximizes your chassis real estate by allowing you to install up to 4 x U.2/U.3 NVMe SSDs (up to 15mm height) into a single standard 5.25" CD/DVD drive bay. With support for the latest 61.44TB U.2 SSDs, this means you can build a 240TB+ high-speed NVMe storage array in just one drive bay.

This makes the MB324V4P-B ideal for applications such as:

  • Edge AI servers
  • Real-time data acquisition systems
  • High-density storage servers
  • Workstations with 5.25" bays requiring NVMe SSD support

Enhanced ExpressTray with Tool-less + Screw Mounting Options

The MB324V4P-B includes ICY DOCK's signature ExpressTray, which simplifies SSD installation with tool-less latching pins that securely hold your U.2/U.3 SSD in place without screws. Unlike typical tool-less designs that lack trays, the ExpressTray provides structural protection during drive swaps and can optionally be secured with screws for applications with frequent vibrations, mobile enclosures, or sensitive enterprise deployments.

Whether you're performing bench testing, configuring storage pools, or running your system in transit, the tray design ensures safe, quick, and repeatable SSD swaps every time.

Next-Gen Connectivity with SlimSAS & PCIe 8-Pin Power

The MB324V4P-B uses 2 x SlimSAS 8i (SFF-8654) connectors, each supporting two PCIe 4.0 U.2/U.3 SSDs at speeds up to 64Gbps per drive. SlimSAS is the preferred modern interface for high-performance NVMe backplanes and supports tri-mode HBA and RAID cards, offering exceptional bandwidth and reliability.

For power delivery, the MB324V4P-B utilizes a PCIe 8-Pin power connector-capable of supplying ample current to all four high-performance SSDs via a single cable, simplifying cable routing and improving airflow in dense systems.
