For just $623.12, down from its list price of $749. That is $89 below the 30-day average of $712.09 and within striking distance of the 90-day low of $622.90.

If you have been watching this drive since launch. This is the deepest cut outside of the initial release window.

What You're Getting

The Helix Mag40 packs 4TB of USB4 storage in a compact aluminum housing with a built-in magnetic ring for MagSafe iPhones. Key specs:

• Magnetic Attachment: Snaps securely to MagSafe-enabled iPhones for cable-free operation on the go.
• USB4/Thunderbolt: Up to 2800MB/s read speeds, compatible with iPhone 15 and newer, plus any USB-C or Thunderbolt computer.
• 4K ProRes Ready: Records directly to the SSD, bypassing internal storage limits for extended video sessions.
• Aluminum Build: Slim, pocket-friendly housing with high-grade TLC NAND flash for consistent performance and endurance.

Who This Is For

Best for iPhone videographers and mobile creators who need extra 4K ProRes storage without carrying a full rig. Also a strong pick for anyone running a USB4 laptop who wants fast, pocket-sized backup.

Skip it if you only need standard USB 3.2 speeds or do not shoot video -- cheaper 1TB and 2TB options exist.

Final Verdict

The magnetic mount and USB4 speed make this a niche but powerful tool for creators shooting ProRes on the go. At $623.12, it is the best price for a 4TB MagSafe SSD in recent months.

If you need the capacity and the speed. This is the one to get.
