6 Best Alternatives to the iStorage datAshur PRO 8GB Encrypted (2026)

How each alternative compares

Integral Crypto-197 8GB Dual Password

The Integral Crypto-197 shares the 8GB capacity and waterproof design of the iStorage datAshur PRO, but it differs in security certification. While the iStorage drive holds FIPS 140-2 Level 3 status, the Integral unit uses FIPS 197 standards with 256-bit AES encryption. A key advantage for you is the dual password system, which allows for master password recovery. This feature addresses a common pain point with PIN-only drives. The Integral drive is slightly larger at 0.55 inches in height compared to the iStorage’s 0.41 inches. It weighs less at 0.64 ounces. If you need a backup access method for your PIN, this drive offers a practical solution without sacrificing rugged durability.

Integral 64GB Crypto-197 Encrypted USB 3.0 Drive

This Integral model provides the same FIPS 197 certification and waterproof construction as the smaller 8GB version, but it doubles the storage to 64GB. It retains the dual password feature for recovery, which the iStorage datAshur PRO lacks. However, it uses USB 3.0 connectivity, whereas the iStorage drive supports faster USB 3.2 speeds. The physical dimensions are identical to the 8GB Integral, measuring 2.28 inches in length. You should choose this drive if your primary concern is compliance with FIPS 197 and you require more space for larger files. The slower transfer speed is a trade-off for the increased capacity and recovery options.

iStorage datAshur Personal2 8GB Encrypted USB Drive

The iStorage datAshur Personal2 is a more compact alternative within the same brand family. It maintains the 8GB capacity and PIN-based authentication but omits the FIPS 140-2 Level 3 certification found in the PRO model. It relies on standard password protection instead. The drive is significantly smaller, measuring 0.2 inches in height and weighing only 0.49 ounces. This makes it easier to carry in tight spaces. You might prefer this version if government-level certification is not a requirement for your work. It offers the same brand reliability and hardware encryption in a smaller form factor, though it lacks the IP57 water resistance rating of the PRO.

Apricorn Aegis Secure Key 3Z 16GB

The Apricorn Aegis Secure Key 3Z offers double the storage capacity at 16GB while maintaining the high FIPS 140-2 Level 3 security standard of the iStorage datAshur PRO. It uses 256-bit AES encryption and password protection. The drive is slightly shorter at 3.25 inches but thicker at 0.3 inches. It weighs more at 1.75 ounces, indicating a sturdier build. It uses USB 3.0 connectivity, which is slower than the USB 3.2 interface on the iStorage drive. This option is ideal if you need more space for sensitive data without compromising on the strict security certifications. The heavier weight may be noticeable during frequent transport.

Apricorn 8GB Aegis Secure Key 3 NX Flash Drive

This Apricorn drive matches the iStorage datAshur PRO in capacity and security certification, offering 8GB of storage with FIPS 140-2 Level 3 compliance. It uses 256-bit AES encryption and password authentication. The physical size is similar, measuring 3.5 inches in length and 0.4 inches in height. It weighs 0.8 ounces, which is slightly lighter than the iStorage drive. The main difference is the connectivity; this model uses USB 3.0, while the iStorage supports USB 3.2. You should pick this drive if you prioritize the specific FIPS certification but do not need the faster transfer speeds of the PRO. It provides a reliable, certified solution with a slightly different form factor.

Apricorn Aegis Secure Key 3 NXC 8GB USB-C Drive

The Apricorn Aegis Secure Key 3 NXC distinguishes itself with a USB-C connector, making it compatible with modern devices without adapters. It retains the 8GB capacity and FIPS 140-2 Level 3 security certification of the iStorage datAshur PRO. It uses 256-bit AES encryption and password protection. The drive supports USB 3.2 speeds, matching the connectivity standard of the original. It is slightly thicker at 0.25 inches and weighs 0.8 ounces. If you frequently use USB-C ports on newer laptops or tablets, this drive eliminates the need for dongles. It offers the same high-level security in a format that aligns with current hardware trends.
