Western Digital My Passport 4TB and Seagate Portable 5TB are both straightforward external hard drives aimed at users who need simple plug-and-play storage for backups and file transport. Public specifications show the Western Digital My Passport 4TB measures a noticeably smaller 4.22 by 2.95 by 0.75 inches and weighs 0.46 pounds, while the Seagate Portable 5TB extends to 4.60 by 3.10 by 0.81 inches and 0.54 pounds, giving the former a clear edge for pocket-friendly portability. Review aggregates indicate both drives deliver comparable USB 3.0 transfer speeds in the 100-130 MB/s range on typical workloads, with the extra terabyte on the Seagate model appealing to users who prioritize raw capacity over size. Neither manufacturer currently publishes official power-consumption figures or warranty durations beyond standard return windows, leaving those details to retailer policies and user reports. The short version: choose the Western Digital My Passport 4TB when a compact form factor and confirmed 4TB capacity matter more than squeezing in an additional terabyte.

Verdict: Pick Western Digital My Passport 4TB if you need a compact drive with known dimensions and a 4TB capacity. Neither publishes power or warranty yet.

Western Digital My Passport 4TB lists at $109.99 while Seagate Portable 5TB lists at $219.99 — Western Digital My Passport 4TB undercuts Seagate Portable 5TB by $110 (100%).
