ICY DOCK ToughArmor MB699VP-B V3 4-bay U.2/U.3 NVMe mobile rack

Quad U.2/U.3 NVMe bay for 5.25" slot

The ToughArmor MB699VP-B V3 fits four PCIe NVMe U.2 or U.3 solid-state drives up to 15 mm tall into a standard external 5.25" optical bay. Each bay connects through an OCuLink SFF-8612 link defined by SFF-9402 Rev 1.1 and supports PCIe 4.0 transfer rates up to 64 Gb/s. A full-metal chassis meets flammability requirements and trays slide out for quick drive swaps.

Workstations needing dense hot-swap NVMe.

This rack suits video editors, server operators and workstation builders who want four enterprise U.2/U.3 drives in a single front-accessible bay with adjustable dual 40x20 mm cooling. It does not accept M.2 modules directly, so systems limited to M.2 slots cannot use it. Buyers without a free 5.25" opening or an OCuLink-capable controller should consider other form factors.

Four OCuLink SFF-8612 ports for PCIe 4.0 x4 per

The enclosure provides four independent OCuLink SFF-8612 connectors, each delivering a full PCIe 4.0 x4 link to its drive bay. Your host controller or adapter must expose four matching OCuLink ports wired to the SFF-9402 pinout; a single port or a different connector type will leave bays inactive. Verify that your card supplies the required lane count before purchase.
