The Western Digital My Passport 1TB and the Seagate Backup Plus Slim 1TB are compact portable hard drives that each pair a 1 TB capacity with USB 3.0 connectivity and straightforward plug-and-play operation for Windows and Mac users. Public specifications and aggregated user reports show the Western Digital My Passport 1TB consistently delivering higher sustained transfer rates that can reach peaks near 5 Gb/s under favorable conditions, while the Seagate Backup Plus Slim 1TB tends to trail by a noticeable margin in real-world file-copy benchmarks. Both models rely on similar 2.5-inch platter designs, yet reviewers note the Western Digital drive runs slightly cooler and exhibits more predictable performance across varying file sizes. Neither manufacturer publishes exact power draw, physical dimensions, or warranty length at the time of most comparisons, leaving those details to aftermarket teardowns and retailer listings. The short version: choose the Western Digital My Passport 1TB when transfer speed matters most.

Verdict: Pick Western Digital My Passport 1TB if fast transfer speed (Up to 5GB/sec) is a priority. Neither publishes power, dimensions or warranty yet.
