ICY DOCK MB994SK-1B 4x 2.5" Mobile Rack Key Lock

Put more storage into less space without giving up control. The ICY DOCK TOUGHARMOR MB994SK-1B is a metal mobile rack built to house four 2.5-inch drives in an internal configuration, making it a strong fit for systems that need high drive density in a compact footprint. The key lock adds a physical layer of access control, which is useful in shared systems, lab environments, and infrastructure where drive removal must be restricted. The metal construction supports a more substantial hardware feel than lightweight plastic alternatives, helping justify its place in deployments where the enclosure is expected to see repeated handling. For builders and IT teams standardizing on 2.5-inch storage, this rack helps turn a single bay into a more efficient storage zone while keeping the installation inside the chassis. It is the kind of component chosen when the cost of downtime, tampering, or wasted space is higher than the price of a basic adapter. The result is cleaner integration, better drive organization, and a more controlled storage environment.
