4-Pack 3.5in X7K8W 0X7K8W SAS SATA Hard Drive Caddy - Hot Swap Bracket

In this review of the 4-Pack 3.5in X7K8W 0X7K8W hard drive caddy, the bottom line is simple: it is a practical, no-frills replacement for servers that require a full-size 3.5in hot-plug drive tray. The reviewer found it most useful for technicians and IT teams maintaining PowerEdge and compatible server lines because it restores proper drive fit and hot-swap functionality without modifying the server. For anyone with the larger 3.5in bays this caddy is the direct and economical fix; it is not suitable for servers with 2.5in bays.

Key Features

• Compatibility: Works with specified 14th generation PowerEdge models and selected 15th and 16th generation systems so replacements match factory drive bays.
• 4-Pack Convenience: Four HDD caddies in the set allow multiple drive swaps or immediate coverage for several bays during a maintenance window.
• Included Mounting Hardware: Ships with 16 mounting screws so each tray can be secured without sourcing extra parts.
• 3.5in Support Only: Designed specifically to hold standard 3.5in hard drives, ensuring a snug fit and proper alignment in hot-plug bays.
• Hot-Swap Bracket: Restores hot-plug functionality and drive removal access for compatible PowerEdge and enclosure models.

Who It's For

IT administrators, system builders, and service technicians who manage Dell PowerEdge racks with 3.5in hot-plug bays will find this 4-pack especially useful for replacements after lost trays or when refurbishing servers. The pack is also practical for labs and small data centers that need multiple spares on hand to reduce downtime.

Users with servers that have 2.5in drive bays should look elsewhere, as these caddies do not accommodate 2.5in drives or adapters. Also, buyers should confirm their specific PowerEdge variant accepts the larger 3.5in tray, since the same server family can include different bay sizes.

Pros & Cons

Pros

• Compatible with a wide list of 14th generation PowerEdge models and select 15th and 16th generation systems, restoring OEM fit.
• Four trays per pack and 16 screws provide immediate readiness for multi-bay maintenance.
• Simple, straightforward design that supports proper hot-swap operation for 3.5in drives.

Cons

• Not usable with 2.5in drive bays, so it is not universal across all server variants.
