Dell SFF 2.5" to 3.5" Adapter

This SMUGDESK R494D bracket converts a 2.5 inch SATA SSD or HDD to fit a standard 3.5 inch drive bay in Dell OptiPlex and Precision small form factor desktops. The ABS plastic caddy matches original tray dimensions for a precise fit and uses a tool-free clip-in design for quick installation. Vibration-dampening construction helps protect the drive during operation.

Suits SATA upgrades on compatible Dell systems

It supports 7 mm thick 2.5 inch SATA solid state drives and laptop-style hard disk drives, making it ideal for storage upgrades or mechanical drive replacements. Builders working with non-Dell chassis or drives thicker than 7 mm should consider a different mounting solution. The adapter does not support drive interfaces other than SATA.

Key spec: 7 mm SATA drive support

The bracket accepts only standard 7 mm height 2.5 inch SATA SSDs and HDDs. Drives with a different thickness or connector type will not mount correctly in this caddy. Verify your drive height before purchase to ensure compatibility.

Questions about this item

Does the R494D caddy add vibration noise when a 2.5-inch SATA drive runs all day?

The shock-resistant ABS housing dampens vibration, so the mounted SATA drive runs quietly in the 3.5-inch bay.

What must my Dell OptiPlex or Precision SFF already have for this bracket to work?

A free 3.5-inch SFF drive bay and a standard SATA data plus power cable.

Will a 7 mm 2.5-inch SATA SSD fit securely alongside the original 3.5-inch drive in my Dell SFF?

Yes, the clip-in tray matches the original bay dimensions and holds the thinner drive firmly without modification.
