Apricorn vs iStorage Drive Specs
USB version
You need to check the interface standard for your computer. The Apricorn Aegis Secure Key 3NX uses USB 3.1. This version offers high-speed data transfer capabilities suitable for modern systems. The iStorage datAshur PRO uses USB 3.2. This is a newer standard that often supports higher bandwidth. If your computer has the latest ports, the iStorage drive may offer better backward compatibility and future-proofing. The Apricorn drive remains fully compatible with USB 3.1 and earlier ports. For most users, both versions provide fast enough speeds for daily backups. However, the newer specification on the iStorage drive gives it a slight technical advantage in connectivity standards.
transfer speed
Data transfer rates determine how long you wait for files to move. The iStorage datAshur PRO lists specific read and write speeds. It reaches up to 169MB/s for reading and 135MB/s for writing. These numbers indicate efficient handling of large files. The Apricorn Aegis Secure Key 3NX does not list specific speed metrics in its provided data. You cannot confirm if it matches the iStorage performance. Without published numbers, you must assume the speeds are comparable to standard USB 3.1 drives. For users who move large datasets frequently, the published speeds of the iStorage drive provide clear performance expectations.
build quality
Physical durability matters for portable storage you carry in pockets or bags. The iStorage datAshur PRO is certified IP57. This rating means it is dust-resistant and can withstand immersion in water up to one meter for thirty minutes. This makes it suitable for harsh environments. The Apricorn Aegis Secure Key 3NX data does not mention any IP rating or specific ruggedness features. You should assume it lacks the same level of water and dust protection. If you work in wet or dusty conditions, the iStorage drive offers superior physical protection. For indoor office use, this difference may be less critical.
security standard
Both drives prioritize data protection through hardware encryption. The Apricorn Aegis Secure Key 3NX uses 256-bit AES XTS encryption. It also meets FIPS 140-2 Level 3 standards. This is a rigorous government certification for cryptographic modules. The iStorage datAshur PRO also uses AES-XTS 256-bit encryption. It similarly meets FIPS 140-2 Level 3 standards. Both drives also hold additional certifications. The iStorage drive lists NLNCSA DEP-V and NATO Restricted certifications. These add layers of compliance for specific government or military needs. The Apricorn drive data does not list these extra certifications. For maximum certified security, the iStorage drive has the edge.
compatibility
You need a drive that works with your existing devices. The iStorage datAshur PRO explicitly lists compatibility with multiple operating systems. It works with MS Windows, macOS, Linux, Chrome, and Android. It also supports Thin Clients, Zero Clients, and embedded systems like Citrix and VMware. This wide range ensures it fits into diverse IT environments. The Apricorn Aegis Secure Key 3NX data does not list specific compatible devices or operating systems. You must rely on general USB standards for its compatibility. The iStorage drive provides clearer assurance for specialized or varied hardware setups.
Which drive fits your workflow
Users needing rugged, portable storage
The iStorage datAshur PRO offers IP57 certification for dust and water resistance. Its compact dimensions and lightweight design make it easy to carry. The USB 3.2 interface provides faster read speeds up to 169MB/s.
