Security and Speed Comparison
data security
iStorage takes the lead with hardware-level encryption. The datAshur PRO uses AES-XTS 256-bit encryption and requires a PIN for access. It holds FIPS 140-2 Level 3 certification, meeting strict government standards for data protection. SanDisk offers Secure Access Software to keep files private. This software-based approach lacks the physical PIN authentication and military-grade certification found in the iStorage model. If you need guaranteed protection against unauthorized access without relying on host computer security, the iStorage design is superior.
read speed
The iStorage datAshur PRO offers faster data retrieval. Its read speeds reach up to 169MB/s. This is significantly higher than the SanDisk Ultra, which tops out at 100MB/s. Both drives support fast transfer protocols, but the iStorage unit moves large files more quickly. If your workflow involves frequent large file transfers, the iStorage drive provides a noticeable performance advantage. The SanDisk speed is adequate for general use, but it cannot match the raw throughput of the encrypted drive.
storage capacity
SanDisk provides much more storage space in this specific comparison. The SanDisk Ultra has 64GB of capacity. The iStorage datAshur PRO in this listing has only 8GB. While iStorage offers larger options like 512GB in other variations, this specific model is limited. If you need to store many documents, photos, or videos on a single drive, the SanDisk unit is the practical choice. The 8GB limit on the iStorage drive restricts its utility for bulk storage needs.
usb version
Both drives offer modern USB connectivity. The iStorage datAshur PRO supports USB 3.2, which is a newer standard than USB 3.0. The SanDisk Ultra uses USB 3.0. Both are backward compatible with USB 2.0 ports. The USB 3.2 interface on the iStorage drive allows for higher bandwidth potential, supporting its faster read and write speeds. For users with newer computers, the iStorage interface is more future-proof, though both will work on older systems.
build durability
The iStorage datAshur PRO is built for rugged use. It is IP57 certified, meaning it is dust and water resistant. This makes it suitable for outdoor or harsh environments. The SanDisk Ultra specifications do not mention any water or dust resistance rating. It is designed for general indoor use. If you carry your drive in a bag with other items or work in dusty conditions, the iStorage build quality offers better physical protection for your data.
Choose your drive by priority
Users needing strong government-grade security
The iStorage datAshur PRO offers FIPS 140-2 Level 3 certification and AES-XTS 256-bit hardware encryption. You enter a PIN to access files, and data is protected even if lost. This model ensures compliance with strict regulations like GDPR and HIPAA for sensitive corporate or personal assets.
People storing large media files
The SanDisk Ultra provides 64GB of storage, which holds significantly more photos, videos, and documents than the 8GB iStorage option. It delivers read speeds up to 100MB/s via USB 3.0, allowing you to move larger libraries of data quickly without waiting for long transfer times on your computer.
Those needing rugged water resistance
The iStorage datAshur PRO is IP57 certified, making it dust and water resistant. This rugged design protects your data from environmental damage during travel or outdoor use. The hardware encryption remains active without requiring additional software installation, ensuring your files stay secure and accessible on any standard USB port.
Budget buyers needing basic capacity
The SanDisk Ultra offers a practical balance of speed and capacity for everyday tasks. With 64GB storage and USB 3.0 compatibility, it handles standard file transfers efficiently. The included Secure Access Software adds a layer of privacy for general users who need more space than smaller drives provide for daily backups.
