Our take
The WD My Passport 4TB red WDBPKJ0040BRD-WESN is a high-capacity portable HDD for a buyer whose computer has a USB 3.0-family port or a USB 2.0 host and who can verify the current offer's exact model. Its useful combination is 4TB nominal capacity and a documented USB 3.2 Gen 1 connection that is backward-compatible with USB 2.0. The key compromise is that those model facts do not identify the condition, included cable, current operating-system support, power arrangement, or current Amazon listing. The historical title's “Renewed” label is not evidence that a present offer is refurbished or renewed.
A buyer who needs a high-capacity portable HDD and has a documented USB 3.0-family or USB 2.0 host path, after checking the current offer's exact SKU and condition.
A buyer who needs a confirmed renewed unit, a directly verified current Amazon ASIN, established bus power, a current compatibility guarantee, or documented console, RAID, or FireWire support.
Pros & cons
What could work for you, and what to consider before buying.
What works in its favor
- WD's product overview maps WDBPKJ0040BRD-WESN to the red 4TB My Passport configuration.
- The portable HDD design combines a nominal 4TB with a USB 3.2 Gen 1 connection.
- WD documents backward compatibility with USB 2.0 hosts, which can preserve a connection path for an older computer.
What to weigh up
- The historical ASIN B0846R3NTN is not verified as a current exact-model offer, and the historical “Renewed” condition is not established for a current listing.
- Saved sources do not establish the exact unit's power arrangement, the present seller's cable or package, or compatibility with a buyer's current computer and software.
- USB 3.2 Gen 1 is an interface description, not a measured file-copy result; no exact-model performance test is saved.

What the features mean for you
Match the full model code
The My Passport family includes multiple capacities and colors, so a family name alone is not enough to identify the item. WD's product overview lists WDBPKJ0040BRD-WESN as the 4TB red SKU. The separate WD product-details page also identifies a 4TB red drive, but it redirected by region when checked; the saved identity relies on the overview's exact SKU line. Use the full code and capacity to distinguish this configuration from neighboring My Passport models. The historical row's Amazon ASIN does not independently establish what a current offer contains.
Capacity helps with a larger archive
The 4TB advertised capacity gives this portable HDD more nominal room than the 500GB and 1TB models in the saved comparison. That can suit a buyer consolidating a larger document, photo, or media archive onto one portable unit. Advertised capacity is not formatted free space, and the source does not provide an exact usable-space figure. Capacity alone also says nothing about a particular unit's health or the transfer time for a real workload. Keep a separate copy of important files rather than treating a single external drive as the only archive.
USB host support is a compatibility path
WD specifies USB 3.2 Gen 1 for this model and states USB 2.0 backward compatibility. That provides a documented host path for both USB 3.0-family and USB 2.0 computers, with the older host setting the connection limit. It does not promise a specific copying speed on a given computer. Confirm the actual port, cable, and current computer support before relying on the drive, particularly with an older system or adapter. The saved sources do not establish Thunderbolt, FireWire, console preparation, or direct television playback for this exact SKU.
Treat software and power as separate checks
The saved identity sources support the model, nominal capacity, color, and USB connection, but they do not establish a current operating-system list, a required file-system conversion, or the exact power arrangement for a present seller's unit. A buyer who needs a particular backup application, encryption feature, one-cable power setup, or compatibility with a current computer should check that requirement against the selected offer and current vendor documentation. Those details are not inferred from another My Passport generation or from a generic family name.
Check the offer and condition before ordering
The historical Amazon title includes “Renewed,” but the inventory does not verify the current status of B0846R3NTN or whether that condition applies to any present listing. The affiliate destination is therefore an exact-model Amazon search for “WD My Passport 4TB Red WDBPKJ0040BRD-WESN,” not a direct ASIN claim. Compare the full model code, red color, 4TB capacity, seller condition, included cable, and return terms on the offer you choose. The saved evidence supports the model profile; it does not establish current price, stock, condition, or the state of an individual drive.
What else to compare
Before you buy
Is WDBPKJ0040BRD-WESN the red 4TB model?
WD's product overview maps that exact SKU to the red 4TB My Passport configuration.
Can it connect to a USB 2.0 computer?
WD lists USB 2.0 backward compatibility. The host connection still limits the interface, and no file-copy speed is measured here.
Does historical ASIN B0846R3NTN prove the current offer is Renewed?
No. The historical title records an old condition label; a current exact offer and its condition remain unverified.
Where can I check the current price?
Use the Amazon link for current offers. Check the exact model, seller, product condition, delivery, and return terms. This page does not display a live price or confirm stock.
