For just $904.79, below its 30-day average of $963.82. The 4TB PRO-G40 has been holding above $960 for the past month, so this dip to $904.79 is a genuine deviation. While the 90-day and 180-day averages run lower ($562.77 and $507.42 respectively), those numbers reflect earlier pricing cycles before recent adjustments. The current discount is a real saving off what this drive has been selling for recently.

What You're Getting

The PRO-G40 pushes Thunderbolt 3 speeds up to 3000MB/s read and 2500MB/s write, moving a 50GB file in under a minute. Dual-mode compatibility works with both Thunderbolt 3 (40Gbps) and USB-C (10Gbps), so it plays nice with modern Macs and PCs alike. The enclosure is built for punishment: IP68 dust and water resistance, 4000lb crush rating, and 3-meter drop protection. An aluminum core pulls heat away from the internal drive to sustain those high transfer speeds during extended sessions.

It ships Mac-ready in APFS format.

Who This Is For

Best for: Video editors, DITs, and photographers who work with large 4K or 8K files and need 4TB of rugged on-set storage. The PRO-G40 is purpose-built for field work where dropped drives and dust exposure are real risks.

If you only need 1TB or 2TB, the smaller capacities hit lower price points, and anyone working exclusively in a studio can get by with less rugged options.

Final Verdict

For $59.03 less than its 30-day average, the 4TB PRO-G40 is a smart pickup for creative professionals who need high-capacity, travel-ready storage right now. The rugged build and Thunderbolt 3 speed make it a genuine workhorse for demanding production environments.
