01 — Seagate
Best overallSeagate Portable 5TB External Hard Drive HDD USB 3.0 for PC
Seagate Portable 5TB External Hard Drive HDD – USB 3.0 for PC provides 5TB mechanical-disk storage through USB 3.0. Seagate's 5TB portable hard drive is the capacity-first option for a laptop owner storing large photo or video archives. It uses a mechanical disk, so expect slower access and more care in transit than with an SSD. I would check the supplied cable and file system, then keep another copy of anything important; one external drive is not a backup plan by itself. Seagate Portable 5TB External Hard Drive HDD USB 3.0 for PC provides 5TB of external hard-disk storage through USB 3.0.

02 — Kosbees
Best for large backups500 GB External Hard Drives Portable Hard Drive for Windows
Kosbees 500 GB External Hard Drives provides 500 GB mechanical-disk storage. Check the exact connector and cable against the computer or console, and format the drive only after copying off any existing files. A desktop enclosure may need separate power. An external USB HDD can store Series X|S-optimized titles, but those games generally need internal storage or an approved expansion card to play. 500 GB External Hard Drives Portable Hard Drive for Windows provides 500 GB of external hard-disk storage through USB 3.0.

03 — YOTUO
Best for compact storageYOTUO 1TB External Hard Drive Portable Storage Expansion HDD
YOTUO 1TB External Hard Drive provides 1TB mechanical-disk storage through USB 3.0. YOTUO's 1TB portable HDD is for a modest archive when buying a 5TB drive would be wasted. I would check the exact USB connection and formatting needs on the laptop before plugging it in. The smaller capacity can be enough for documents and occasional media, but it gives less room for a growing photo library. YOTUO 1TB External Hard Drive Portable Storage Expansion HDD provides 1TB of external hard-disk storage through USB 3.0.

04 — UnionSine
Best for frequent transfersUnionSine 500GB Ultra Slim Portable External Hard Drive
UnionSine 500GB Ultra Slim Portable External Hard Drive provides 500GB of external hard-disk storage through USB 3.0. UnionSine's slim 500GB HDD is a light, low-capacity option for moving ordinary files between compatible computers. I would verify the connector and available space after formatting rather than rely on the advertised number alone. It is not the right choice for a large video archive, and a dropped mechanical drive can still fail despite a slim case.

Best valueModusTech Facet 500GB External Hard Drive Portable USB-C/USB
ModusTech Facet 500GB External Hard Drive Portable USB-C/USB 3.1 Plug & Play provides 500GB mechanical-disk storage through USB-C. ModusTech Facet 500GB is the USB-C-oriented small archive choice when port fit matters more than capacity. I would inspect the exact cable and warranty because its low-cost enclosure is less established than WD's. A mechanical disk remains vulnerable to drops, so it makes more sense for occasional transfers than for files used constantly on the road.
