6 Best Alternatives to the Oyen Digital Helix Mag40 4TB USB4 (2026)

Comparing alternatives to the Helix Mag40

Crucial X10 Pro 4TB Portable SSD

The Crucial X10 Pro 4TB uses a USB-C interface instead of USB4. This limits its maximum sequential read speeds compared to the Helix Mag40’s 2800MB/s capability. However, it offers a much lighter profile at 1.13 ounces versus 6.4 ounces. The X10 Pro is also significantly thinner at 0.39 inches. You lose the magnetic attachment feature found on the Helix. This option suits users who prioritize portability and rugged durability over the highest possible transfer rates or iPhone MagSafe compatibility. It is a solid choice if you need a lightweight drive for general creative work rather than direct iPhone video capture.

Glyph Atom EX20 4TB Rugged NVMe SSD

The Glyph Atom EX20 4TB is a rugged NVMe SSD designed for professional media workflows. It shares the 4TB capacity but focuses on build quality and reliability rather than raw interface bandwidth. The Helix Mag40 offers faster USB4 speeds up to 2800MB/s. The EX20 is built for tough environments where durability matters more than the absolute fastest transfer rates. It lacks the magnetic attachment and USB4 interface of the Helix. This drive is ideal for filmmakers and photographers who need a robust, reliable storage solution for field work. You should choose this if you prioritize physical protection and consistent performance in harsh conditions over high-speed connectivity.

Glyph Atom EX40 4TB USB4 Portable SSD

The Glyph Atom EX40 4TB USB4 matches the Helix Mag40’s USB4 interface, offering top-tier speed for professional video workflows. It shares the high-performance focus but emphasizes rugged build quality for travel. The Helix Mag40 includes magnetic attachment for iPhones, which the EX40 lacks. Both drives target professional creators needing reliable, high-speed storage. The EX40 is ideal for those who need USB4 speeds without the specific iPhone integration. You should pick this if you want a rugged, high-bandwidth drive for laptops or desktops. It is better suited for stationary or ruggedized use cases where magnetic mounting is not a requirement.

iStorage diskAshur2 4TB Hardware Encrypted SSD

The iStorage diskAshur2 4TB prioritizes data security with hardware encryption and password protection. It uses a standard USB interface, which is slower than the Helix Mag40’s USB4 connection. The Helix offers faster 2800MB/s reads for video workflows. The diskAshur2 is heavier at 7.62 ounces and larger in dimensions. It lacks magnetic attachment and high-speed transfer capabilities. This drive is best for professionals in regulated environments who need certified data protection. You should choose this if security compliance is your primary concern. It is not suitable for users who need fast external storage for 4K video editing or iPhone connectivity.

Samsung 860 EVO 4TB 2.5-Inch SATA SSD

The Samsung 860 EVO 4TB is a 2.5-inch SATA SSD designed for internal upgrades in desktops and laptops. It uses the older SATA III interface, which is significantly slower than the Helix Mag40’s USB4 speeds. The Helix offers up to 2800MB/s, while SATA III is limited to much lower throughput. The 860 EVO is not portable in the same way and lacks magnetic attachment. It is ideal for users upgrading internal storage rather than needing external portable drives. You should pick this if you are installing a drive inside a computer. It is not suitable for external video workflows or iPhone connectivity due to its interface and form factor.

iStorage diskAshur PRO2 4TB Hardware Encrypted SSD

The iStorage diskAshur PRO2 4TB offers FIPS 140-2 Level 3 validated security with hardware encryption. It uses a USB 3.2 interface, which is slower than the Helix Mag40’s USB4 connection. The Helix provides faster 2800MB/s reads for creative tasks. The PRO2 is larger and heavier at 7.94 ounces. It lacks magnetic attachment and high-speed performance. This drive is best for users handling sensitive data who must meet strict regulatory standards. You should choose this if security certification is mandatory. It is not ideal for users who need fast external storage for 4K video or iPhone compatibility due to its focus on compliance over speed.
