This article covers LaCie ポータブルSSD Portable SSD 1TB USB-C Mac.

Overview

LaCie has long been synonymous with premium external storage, and the LaCie Portable SSD 1TB STKS1000400 continues that tradition. This compact external SSD delivers sequential read speeds up to 1050 MB/s over USB 3.2 Gen2, making it an excellent choice for creators who frequently move large photo libraries or 4K video files.
Measuring just 10mm thick and weighing only 45 grams, it's designed to slip into any laptop bag or even a large pocket. The drive is bus-powered, so no separate power adapter is needed—just plug the included USB-C cable into a Mac, Windows PC, or iPad. It ships formatted as exFAT, ensuring out-of-the-box compatibility across major operating systems.
In the market, this LaCie SSD occupies a premium mid-high tier for portable storage. What sets it apart is the included 3-year limited warranty with one free data recovery service, plus a one-month membership to Adobe Creative Cloud Complete. These extras add tangible value for creative professionals who rely on their data every day.

Compatibility Guide

  • The drive uses USB 3.2 Gen2 (USB-C) with a maximum theoretical bandwidth of 10Gbps. It is backward compatible with USB 3.2 Gen1 and USB 3.0, though speeds will drop to the host's limit.
  • Compatible with Windows 10 and later, macOS 10.12 and later, and iPadOS (iPad models with USB-C).
  • Power is supplied entirely over the USB bus. Most modern laptops and desktops can deliver enough power, but some older USB-A ports may struggle. In that case, use a self-powered USB hub or a USB-C to A adapter with external power.
  • Only a USB-C to C cable is included. If your computer lacks a USB-C port, you'll need to purchase a USB-C female to USB-A male adapter separately, and performance will be capped at USB 3.0 (5Gbps).

Product Info

Model number: STKS1000400. Capacity: 1TB. Dimensions: 50×80×10.6 mm (W×D×H). Weight: ~45g. Color: black with silver accents. Warranty: 3 years limited, with one free data recovery service within the warranty period. Includes a one-month Adobe Creative Cloud Complete membership.
Market positioning: mid-high tier portable SSD aimed at creative professionals. While raw speed is competitive, the real differentiators are the data recovery warranty and Adobe bundle, making it a value-oriented choice for users who prioritize peace of mind and software ecosystem over absolute price.

Best Use Cases

  • Photographers and videographers: If you frequently transfer RAW files or edit 4K footage on the go, the 1050 MB/s read speed will significantly reduce wait times. The included Adobe CC membership is a nice bonus. Not ideal for casual users who only need occasional backups—a cheaper HDD or slower SSD would suffice.
  • iPad Pro / iPad Air users: The SSD connects directly to the iPad's USB-C port, allowing you to edit videos from the external drive without filling internal storage. Works seamlessly with the Files app. Not recommended for users with Lightning-based iPads, as an adapter may introduce speed and reliability issues.
  • MacBook travelers: The slim, lightweight design fits neatly beside a MacBook, and bus power means no extra cables or power bricks. Ideal for extending the limited internal storage of modern MacBooks. Less suitable for those who exclusively use Windows and prefer NTFS formatting (exFAT works but lacks journaling).

Things to Consider

  • USB-A users need an adapter: The included cable is USB-C to USB-C only. If your computer has only USB-A ports, you'll need a converter (USB-C female to USB-A male). When using such an adapter, the connection drops to USB 3.0 speeds (max 5Gbps), so you won't get the full 1050 MB/s.
  • Data recovery service is one-time only: While the 3-year warranty includes one free data recovery attempt (even for physical damage like drops or immersion), it doesn't guarantee 100% recovery. Always maintain a secondary backup for critical data.
  • Competition: At similar price points, the Samsung T7 Shield offers slightly faster speeds and IP65 dust/water resistance, while the SanDisk Extreme Portable SSD provides similar ruggedness. LaCie's edge is the data recovery service and Adobe bundle, but for outdoor use, the T7 Shield may be better.
  • Overkill for light users: If you only back up documents and photos occasionally, a 1TB portable HDD costs half as much. The LaCie's speed premium only makes sense if you regularly move large files.

FAQ

Q: Can I use this SSD with Windows without reformatting?
A: Yes, the drive comes pre-formatted as exFAT, which is read/write compatible with both macOS and Windows out of the box. However, exFAT lacks journaling, so always safely eject before disconnecting. If you reformat to NTFS for better data integrity on Windows, the drive becomes read-only on Mac without third-party tools.
Q: How does the data recovery service work?
A: Within the 3-year warranty period, if you lose data due to accidental deletion, overwriting, drop, or wa
