LaCie Mobile Drive

Bottom line: The LaCie Mobile Drive ($299.99 on Amazon as of 2026-10-07): 4TB in a 2.5-inch pocket enclosure - full photo and video archive on one drive; main trade-off: spinning 2.5-inch HDD, so transfer speeds trail any SSD in this price range.

Pros & Cons

Pros

  • ✓ 4TB in a 2.5-inch pocket enclosure - full photo and video archive on one drive
  • ✓ Two-year Rescue Data Recovery Services included, not a paid add-on
  • ✓ USB-C native with USB 3.0 support for older USB-A laptops
  • ✓ Works on both Mac and Windows without buying a second drive

Cons

  • ✗ Spinning 2.5-inch HDD, so transfer speeds trail any SSD in this price range

  • ✗ Rescue Data Recovery coverage stops after two years
  • ✗ Bundled backup software is LaCie's own, not a cross-platform standard

Manufacturer description

The LaCie Mobile Drive 4TB (STHG4000400) is a pocket-sized external hard drive built for people who move between machines and need their archive to come along. The Moon Silver aluminum enclosure matches a MacBook on a desk and slips into a laptop sleeve without adding bulk, and the 2.5-inch 4TB capacity gives you room for years of photo libraries, video projects, and full-system backups on a single drive. Connectivity is the practical draw here. The drive ships USB-C ready and includes USB 3.0 support, so it plugs into current USB-C laptops directly and still works with older USB-A ports on…

SpecPicks Verdict

SpecPicks scored LaCie Mobile Drive using a rating × review-volume × price-fit model applied to published specs and reviews across the external storage category. LaCie's external storage lineup sits within the broader category mid-tier; price and specs are the deciding factors over brand loyalty here. Judge it on the specification table and the price rather than on sentiment: check the figures that decide your use case, then put it side-by-side with two or three close alternatives in the Compare tool before clicking through.

Common buyer scenarios for external storage of this kind: matching it to an existing build, replacing a failing part, or upgrading from a previous-generation equivalent. Check the spec table below against your current setup — particularly socket / form-factor / power-rating fields — and confirm compatibility on the retailer's listing before purchase. Prices and stock are set by the retailer and may have moved since this page was last updated.

Frequently Asked Questions

Does the LaCie Mobile Drive work with a Mac and a Windows PC?

Yes. LaCie lists the Mobile Drive as usable on both Mac and Windows. If you plan to move files between the two regularly, check the drive's out-of-box format on the product listing and reformat to a shared filesystem if needed.

Will it connect to my older laptop that only has USB-A ports?

Yes. The drive is USB-C, and LaCie includes USB 3.0 support so it connects to current USB-C laptops and to older machines via USB 3.0 to USB-C.

What warranty and data recovery coverage comes with it?

LaCie includes a two-year limited warranty plus two years of Rescue Data Recovery Services. Check the product listing for current terms and regional coverage details.

Is 4TB enough for a full computer backup?

For most laptops, yes - 4TB comfortably holds a full system image plus years of photo and video archives. The included backup software lets you schedule those backups rather than copying folders manually.
