Incorporating eight enterprise-grade U.2/U.3 NVMe drives within a single 5.25-inch external bay, the ToughArmor MB998V4P-B leverages dedicated PCIe 4.0 x4 lanes per module for host-dependent throughput up to 64 Gbps. Its full-metal enclosure ensures structural durability while dual 40Ã40Ã20 mm fans deliver active cooling that prevents thermal throttling during sustained workloads. This combination of ultra-high density and reliable heat management optimizes performance in demanding server, workstation, and critical industrial environments.
Hot-swap frame maximizes capacity for server racks, HPC clusters
By leveraging a mobile hot-swap tray design, the MB998V4P-B packs eight enterprise-grade U.2/U.3 NVMe SSDs into a single 5.25-inch bay, achieving extreme storage density while preserving modular serviceability. This configuration optimizes rack space utilization in data centers and HPC environments, delivering real-time 8K video performance with sustained throughput. Transactional database workloads benefit from IOPS capacity, and the tool-free trays enable rapid maintenance, making it an ideal solution for storage infrastructures.

Each SSD resides in its own detachable ToughArmor tray, enabling convenient, tool-free insertion and removal without powering down the host system. The hot-swap capability streamlines drive maintenance and replacement, minimizing downtime in mission-critical environments. For settings prone to mechanical vibration, optional screw mounts provide enhanced retention and stability. Integrated front-panel LEDs deliver immediate visual feedback, indicating individual drive power status and real-time activity with distinct illumination patterns for health monitoring.
Four SlimSAS 8i Ports Provide Dual U.2/U.3 SSD Connectivity
Four SlimSAS 8i (SFF-8654) ports provide direct PCIe Gen4 connections for up to eight U.2/U.3 NVMe SSDs when paired with Tri-Mode HBA or RAID cards in NVMe-only mode. Each port supports two drives at full PCIe 4.0 x4 bandwidth, delivering high I/O throughput with minimal latency. A single PCIe 8-pin power connector efficiently supplies consistent power to all eight modules, streamlining cabling and simplifying chassis integration in dense storage configurations.
All-Metal Chassis Enables Robust Operation In Harsh Industrial Environments
Constructed entirely from robust metal, the chassis, tray, and frame endure the demanding conditions found in industrial, military, and medical applications. The all-metal build not only provides structural integrity against shock, vibration, and corrosive environments but also ensures superior thermal conductivity. By efficiently transferring heat away from the attached SSDs, this design minimizes temperature spikes, throttling, and potential failures, thereby extending long-term service life and reliable high-performance operation under workloads.
EMI grounding secures SSDs, prevents ESD, maintains signal integrity

Comprehensive EMI grounding through secure SSD mounting provides robust protection against electrostatic discharge. By ensuring a continuous conductive path, this method preserves signal integrity and reduces electrical interference across PCIe 4.0 lanes. In high-speed storage environments, reliable grounding prevents voltage spikes and electromagnetic disturbances that could corrupt data. The design integrates seamlessly into assembly, offering stability, improved reliability, and minimized data loss risks in demanding enterprise and edge computing systems.
Dual 40Ã40Ã20mm Fans Ensure Optimal Cooling For Eight SSDs
Two 40Ã40Ã20 mm high-performance fans generate a focused stream of air across all eight SSD drives, maximizing heat dissipation and maintaining operating temperatures. Combined with strategically positioned ventilation openings in the chassis, this active cooling system ensures consistent airflow distribution, preventing hotspots and reducing the risk of thermal throttling. Even under sustained heavy workloads, the fans and vents collaborate to ensure each drive operates at peak performance while prolonging longevity.
Universal compatibility enables seamless integration with top NVMe hardware
The MB998V4P-B ensures seamless integration with leading mainboards, Tri-Mode HBAs, and M.2 expansion kits from Adaptec, Areca, Broadcom, HighPoint, and Supermicro. It leverages an interactive NVMe Storage Configurator that guides systems integrators through selecting the optimal drive trays, SlimSAS cables, and adapter breakout modules. This utility simplifies deployment planning by verifying interface compatibility, bandwidth requirements, and power delivery specifications, minimizing setup errors and accelerating deployment in enterprise and DIY environments.
