ICY DOCK ToughArmor MB699V5P-B 4-Bay PCIe 5.0 U.2/U.3 NVMe SSD Mobile 5.25" Drive Bay Rack Enclosure

Introducing the ToughArmor MB699V5P-B

The ToughArmor MB699V5P-B packs next-generation performance and rugged durability into a compact mobile rack solution, integrating up to four enterprise U.2/U.3 NVMe SSDs (7-15mm height) into a single external 5.25" optical drive bay. With PCIe 5.0 support delivering transfer speeds of up to 128Gbps per drive through dual MCIO 8i (SFF-TA-1016) connectors, a redesigned airflow-optimized enclosure, and a lightweight aluminum housing, the MB699V5P-B is built for mission-critical applications in servers, workstations, and compact systems where maximum speed, security, and reliability are essential.

Built for High-Performance Applications

The MB699V5P-B is designed for workflows that demand extreme I/O performance and hot-swappable NVMe SSD access. It is particularly well-suited for edge computing nodes, HPC clusters, and AI/ML training systems that rely on fast dataset streaming. Industrial imaging and medical diagnostic platforms also benefit from its removable design, enabling quick SSD replacement during maintenance. In addition, the MB699V5P-B is an excellent fit for system integrators, labs, and R&D environments, where frequent SSD swaps are necessary for validation, testing, or rapid dataset changes. This makes it a versatile solution that bridges enterprise-grade performance with flexible deployment scenarios.

Seamless Compatibility with Enterprise Controllers

The MB699V5P-B is fully compatible with the latest enterprise-grade controllers, including Broadcom, HighPoint, and Adaptec Microchip. We actively collaborate with controller manufacturers to validate performance and interoperability, ensuring that choosing ICY DOCK means not only investing in a rugged enclosure but also benefiting from ongoing technical support and long-term compatibility across platforms.

Next-Gen PCIe 5.0 Performance

With PCIe 5.0 delivering up to 128Gbps per SSD, the MB699V5P-B offers double the bandwidth of PCIe 4.0 and four times faster than PCIe 3.0. This exceptional speed makes it a perfect fit for applications such as:

• High-resolution video editing and playback (8K/12K workflows)
• Real-time scientific simulations and AI/ML data training
• High-frequency trading and transactional databases
• Large-scale virtualization and cloud computing environments

Removable Drive Tray & Space-Saving Design

The ToughArmor EZ-Slide Mini trays support all standard 7mm and 15mm U.2/U.3 SSDs, while the bay design accommodates drives ranging from 5mm to 15mm in height. By consolidating four enterprise NVMe SSDs into a single 5.25" bay, the MB699V5P-B saves valuable system space—an advantage for compact servers, workstation builds, and edge computing systems where expansion slots and drive bays are limited.

Maximising Cooling Performance

The MB699V5P-B is engineered with a dual-PCB horizontal layout that dramatically enhances airflow compared to previous generations. This optimized design is paired with two 40×40×10mm cooling fans and a lightweight all-aluminum housing, ensuring stable thermal management for PCIe 5.0 SSDs under continuous workloads.

Quiet & Controlled

In addition to improved airflow, the new cooling system also delivers quieter operation, with fan noise reduced from 40dB in the previous generation to just 27.5dB - a 31% reduction. This combination of efficient cooling and lower noise makes the MB699V5P-B ideal for performance-critical environments where both reliability and acoustics matter.

EMI Grounding Technology

Each removable drive tray includes EMI grounding to protect drives from electrical interference during insertion, ensuring a stable and secure environment for sensitive enterprise-grade NVMe SSDs.

ToughArmor Protection

Built entirely from metal—including the enclosure and EZ-Slide Mini trays—the MB699V5P-B meets the toughest industrial requirements for reliability and safety. Its rugged construction is suitable for military, medical, in-vehicle, and factory automation systems. The all-metal tray design (MB991TRAY-B) ensures long-term durability, even under frequent drive swaps or transport.

Convenient Utility & Accessibility

The front of the ToughArmor features individual drive status LEDs that clearly indicate power, activity, and no-drive status. With Active Power Technology (APT), the LEDs only illuminate when a drive is installed, reducing unnecessary power consumption. For added security, the tray integrates an eagle-hook lock system to prevent accidental ejection, ensuring your drives remain safe and stable during operation.
