What customers say
Customers overwhelmingly praise the IronKey D300S for its uncompromising security and robust build quality. Users in regulated fields highly value the FIPS 140-2 Level 3 validation, seeing it as essential for compliance with regulations like HIPAA and GDPR. The physical construction is frequently described as rugged, instilling confidence in its durability and tamper resistance. While strict security protocols like mandatory complex passwords are a necessary trade-off, users trust the drive for unparalleled data protection. Performance is reliable, though secondary to security. Despite a premium price, most agree the enterprise-grade protection justifies the investment, resulting in high user trust and low failure rates.
Know before you buy
For security reasons, there is no password recovery option. If you exceed the ten failed password attempts, the drive will automatically trigger a lockdown and wipe its encryption keys, rendering the data permanently inaccessible.
No, the encryption and decryption processes occur entirely on the drive itself. This means you can use it on any compatible system without leaving a trace of your data or software footprints on the host computer.
The drive features a rugged zinc casing designed to withstand physical impact. It is also IEC60529 IXP8 certified, meaning it can remain submerged in water up to 4 feet deep without compromising your data.
The virtual keyboard allows you to enter your password using your mouse rather than your physical keyboard. This protects your credentials from being intercepted by potential hardware-based keyloggers on the computer you are using.
Yes, the drive is backward compatible with USB 2.0 ports, though you will experience slower data transfer speeds compared to the USB 3.1 Gen 1 interface.
This certification indicates that the drive meets high-level government security standards. It confirms that the hardware is tamper-evident and designed to detect and respond to physical attempts to access the internal components.
