Specifications side by side

How to choose the right one

1. Check hardware encryption

   You should look for drives with built-in hardware encryption. This feature encrypts data on the drive itself, not just via software. The iStorage diskAshur2 1TB includes this for robust protection. It ensures your files remain secure even if the drive is lost. You do not need to install additional software to encrypt your data. This adds a layer of security that is always active. It is essential for users who handle sensitive personal or business information.

2. Verify FIPS certification

   If you work with regulated data, check for FIPS validation. The diskAshur PRO3 1TB is FIPS validated, meeting strict government standards. This certification ensures the drive meets specific security requirements for sensitive information. You should choose this model if your organization requires compliance with these standards. Other drives like the diskAshur2 lack this specific validation. FIPS certification provides proof that the encryption meets rigorous testing protocols. It is critical for professionals handling classified or highly confidential data.

3. Review physical dimensions

   Portable drives vary in size, so check the dimensions carefully. The diskAshur PRO2 measures 3.31 by 4.88 inches. The diskAshur3 is slightly larger at 3.27 by 5.16 inches. You need to ensure the drive fits in your bag or pocket. Larger drives may offer more robust construction but less portability. Compare the width and length to your carrying case. The height also matters for slim profiles. Choosing the right size ensures you can transport your secure data easily.

4. Consider weight and build

   Weight affects portability and durability. The diskAshur PRO3 weighs 1.54 pounds, which is heavier than other options. The diskAshur2 weighs 7.62 ounces, making it lighter to carry. You should consider how often you move the drive. Heavier drives may feel more solid but are less convenient. Lighter drives are easier to transport but may feel less rugged. Check the weight in the specifications to gauge the build quality. This helps you decide between maximum portability and a sturdier feel.

5. Look at color options

   Color can help you identify your drive quickly. The diskAshur2 comes in Fiery Red. The diskAshur PRO2 is Graphite. The diskAshur3 is Ruby Red. The diskAshur PRO3 is Black. You might want a distinct color to avoid mixing up drives. This is useful if you have multiple secure storage devices. It is a small detail but helps with organization. Check the available colors in the product specifications. Selecting a color that stands out can save you time when locating your drive.
