Users Complain About
Best For
Field‑based creatives such as cinematographers, documentary filmmakers, and photojournalists who need fast, durable storage on location; mobile workstations handling 4K/8K editing; high‑resolution scratch‑disk workflows; mission‑critical backups in harsh environments; and Mac users needing out‑of‑the‑box compatibility.
Not Ideal For
Users without Thunderbolt 3/4 ports who cannot leverage full speed; budget‑conscious buyers due to high cost per gigabyte; Windows‑only users seeking plug‑and‑play compatibility; and anyone needing a longer or higher‑quality cable included.
Expert Opinion
Professional reviewers lauded the PRO‑G40 for its blistering Thunderbolt 3 performance, IP68‑rated ruggedness, and robust 5‑year warranty. Tom's Hardware highlighted its portability and thermal design, while Filmtools emphasized its suitability for on‑location video work. However, PCMag retracted its endorsement in 2023 after numerous user reports of data loss and firmware failures, urging caution until the issue is resolved.
What Users Say
Everyday users rave about the drive’s lightning‑fast transfers and rugged construction, especially for field photography and video production. Recurring complaints focus on the short, sometimes defective Thunderbolt cable, the hassle of reformatting for Windows, and occasional data‑loss incidents that echo PCMag’s warnings.
Common Complaints
Defective or underspecified Thunderbolt cable causing instability; difficulty reformatting to Windows because of the EFI partition; reports of unexpected data loss or drive failures; short cable length limiting practical use.
What People Are Saying
“Do not buy! ... the under spec. / defective cable that came with the drive”
