Precision T7820 Hard-Drive Adapter

This adapter lets you install additional 3.5 inch or 2.5 inch SATA or SAS drives into the four internal bays of a Precision T7820 tower. It is intended for engineers and creators who need extra local storage for large project files, simulations or render output.

Tool-Less Installation and Fit

The T7820 chassis uses a tool-less drive carrier system so the adapter slides into a bay without screws. Alignment tabs on the carrier must engage the chassis rails fully; if they do not seat, the drive will not be detected and the bay door may not close.

Suits T7820 Storage Expansion Only

This part suits owners of a Precision T7820 who want more than the supplied 16 TB HDD and 512 GB M.2 SSD. It does not add NVMe slots, PCIe lanes or external ports, so builders needing faster scratch disks or additional GPU power should look at other upgrade paths.

Questions about this item

How can I verify the 128GB DDR4 memory is recognised after setup?

Open Task Manager or System Information in Windows 11 Pro and confirm the installed RAM shows 128GB across the 12 DIMM slots.

What storage drives and adapters are included with the T7820?

The workstation ships with one 16TB 3.5 inch HDD and one 512GB M.2 SSD installed; the four internal SATA bays accept additional 3.5 or 2.5 inch SATA or SAS drives without extra adapters.

Which memory capacity should I choose for large CAD assemblies?

The system arrives with 128GB DDR4 and supports up to 768GB across 12 slots, so you can add matched DIMMs later if projects outgrow the factory configuration.
